scale for each layer respectively. The controls of Visible Scale and Reference Scale are modified; users can choose the frequently-used and current map scale rapidly. When the current map scale is not within the range of Visible Scale of the layer, the layer will be marked with gray check in Map Content window. The whole new Symbology type, Unique Values (multi-fields), can classify the attributes of 3 fields at most. The display of vector layer supports to classify null data in the assigned field. The new settings of Bar Chart enable users to use Leader Line when the charts are too closed on the map. The new settings of Pie Chart enable users to use Leader Line when the charts are too closed on the map. Moreover, the size of the pies can be decided by the values in a field or the sum of fields. The improved Dot Density settings can preview the dot distribution in the sparest and densest area. The classification settings in Graduated Color no longer use precision but use field precision. The classification includes Equal Interval, Quantile, Natural Breaks, and Defined Interval. To set the values in the classification in Graduated Color and Graduated Symbol, you only need to input the maximum in a class. Then, the values in other classes will be adjusted automatically. The classes can be manipulated by multi-select. The graduated symbol for line layer can display the lines with different width to present the lines in different classes. To add value in Unique Values settings, users are allowed to input the value they need. To set the transparency of feature layers, you can set the transparency of fill symbol, line symbol, etc at the same time in Display tab rather than set the symbols respectively.

3.1 Exploring Your Data 3.2 Working with Map Data 3.3 Editing the Map Data 3.4 Working with Attribute Data
A map is composed of several layers which record vector data or raster data. When viewing the map, users can set the visibility of each layer and search the features with different tools. Besides knowing the spatial location of features, users can also apply the attribute tables to know the data behind the features. The attribute data not only contain the numeric data, such as area, length, etc but also the text data, like name, classification, and so on. Therefore, you can use the statistics function and sorting function to query the attribute table. Meanwhile, Users are allowed to edit the position and geometry of the features. The chapter mainly introduces the basic functions of SuperGIS Desktop and help users to get familiar with the manipulations. Exploring Data introduces how to navigate the existing map data and how to use the tools to read the map easily. Working with Map Data not only shows the settings of layers but also the selection of features and statistics. Moreover, Editing Map Data also presents the ways to add new layers, edit vertices. At last, Working with Attribute Data provides the manipulation of viewing and editing attribute table. The ways to relate and join tables will be introduces as well. Thus, users can query the features and know the related attributes simultaneously.

Relating Tables
Relating tables is to relate the fields of the same properties from two layers and make a relation on properties of the corresponding fields. After the Tables are related, whenever inquiring features in one of the two layers, the system will tell you not only the data of the feature recorded in the belonging layer but also the data of the feature recorded in the other one. The information will be revealed in the Identify dialog box.

Let’s take Zhongshan file for example to explain how to set up the Relate function, POI layer and Park layer both have the attribute properties of School in features. Next, you could right-click the POI layer name in Table of Contents and then click Properties and enter the Relate and Join tab. In Relate, click Add and the Relate dialog box shows up. In Source Field select a field, and select the layer you want to relate in Table and select the field. In Name you could enter a name or remain the default value. If the layer you want to relate is not listed in Table of Relate Target, click Open File to choose the data you need by yourself. After settings are finished, click OK.

3-36

SuperGIS Desktop 3.0

Go back to the map window, select the Identify button on the map toolbar and select a feature on the POI layer, which you just set as the Source Field. You will see in the left panel the level under POI is the feature you just selected; in this example, the selected feature is School. And you will find one more level, the layer you just selected as the Relate Target, Park layer, under this feature. The level under Park layer contains all its features of attribute properties as school.

Joining Tables
Joining Tables is to join the tables of two layers by a specified attribute field (this field needs to have the same properties, but the heading and order of the field could be different) as the connection field to join the two tables. The system will join the target table to the table of source layer based on this specified field. The way to join the two tables is to form a new attribute table by connecting the properties of target table to the array of the properties of specified field of the source table through the specified field.

The settings of Join can also be set in the Relate and Join tab in Layer Properties dialog box. Firstly click the Add button in Join and specify a field in Source Field in Join dialog box as the

connection field to join the two tables. Select the table you want to join in Table of Join Target, if the table you want to add is not listed in Table, click Open File and the Open dialog box

shows up. In the next, select the file you need, the file could be feature layer, *.dbf file or *.xls file. Then select the field with the same attribute properties as the source field in Field of Join Target, click OK when settings are finished.

Open the attribute table of the layer having the source filed and you will see some extra fields besides the original fields added in the table. Each field’s name will be modified to the format of “layer name (or filename).original field name.” Take the figure below as an illustration, this table is the result of joining attribute tables of POI layer and school layer. The table displays the current corresponding data from school layer. <NULL> in the table represents no data, but it does not refers a blank record; while the blank grid represents a blank record instead of no data.

4.2 Creating a Map
No matter which type of map you want to create, the first step is to click New. To create a new map, you can click File menu and choose New. Then, a new blank map is created.

The second way is to click Open button on Standard toolbar.

As a new map is created, you can add layers to the map to edit your map. When you complete a map, you need to save the file. The file is a Project. Therefore, if the manual mentions Open a Project, it means to open a file.

4-4

SuperGIS Desktop 3.0

4.3 Adding Layers
The second step to create a map is to add the layers you need. Besides the GEO file defined by SuperGIS Desktop, Shapefile, MIF and CAD files are also supported. The supported image files include SID, ECW, BMP, JPG, Tiff, GIF, PNG and so on. There are different manipulations to set the layers of different formats. How to add layers is going to be introduced; the detailed settings will be presented in the following section.

In SuperGIS Desktop, there are 4 ways to add layers. First, click Add Layer button on Standard toolbar.

Or you can right-click Layers in the table of contents and click Add Layer.

4-5

Chapter 4 Setting and Managing Layer

In the two ways mentioned above, Add Layer window will show up. Choose the folder the layer saved in and click Open. The selected layer will be added in the map window. The files in Add Layer window are listed with the icons presenting its geometry; you can add multiple layers at the same time.

You also can right-click Layers in the table of contents and click Recent Layer List, and the file list appears. You can choose a layer and add the layer directly.

4-6

SuperGIS Desktop 3.0

In addition, you can open a folder and drag the layer you need to the table of contents. The layer will be displayed in the map window directly.

4-7

Chapter 4 Setting and Managing Layer

Add Layer tool enables you to add the layer you want to display. If the layer you add is vector layer, SuperGIS Desktop will randomly define the symbol type and color for the layer. If you would like to modify the setting, you can modify them in Layer Properties. Once the file is saved, the settings will be saved, too. Therefore, next time you open the file, the layer will be displayed based on your settings.

Besides vector layers, there are also image layers (i.e. raster layers). SuperGIS Desktop supports several raster formats, such as SID, ECW, BMP, JPG, Tiff, GIF, PNG, etc.

The way to add image layer is the same as the way described above. Click Add Layer button on Standard toolbar, and Add Layer window shows up. Choose the image file you need and click OK. The image layer will be displayed in the map window.

Take the image file for example. You can add vector layer and image layer into the map at the same time. The map window will display like the following graph.

4-8

SuperGIS Desktop 3.0

Furthermore, besides the vector and raster formats, SuperGIS Desktop also supports the display of CAD format. The way to add CAD format is the same as the way mentioned previously. However, what should be noted is that CAD file format is special so that the CAD file can be only viewed and overlaid in SuperGIS Desktop. The legends cannot be modified, and the attributes cannot be identified. Additionally, CAD format contains points, polylines, polygons, and annotations, so the table of contents also lists the 4 types of features. You can tick the layer you want to display and remove the tick of the layer you do not need. The map window will display the map according to your settings.

4.4 Importing and Exporting Layers
When you are editing a map, you might edit multiple layers at a time. Therefore, after you finish editing, you can Export all the layers as a *.slr file. Firstly, right-click Layers in the table of contents and click Export Layer File. Then, Save As window shows up. Choose the folder you want to save the file in, enter the file name, and click Save. Then, all the layers are exported.

During the process of editing map, you might need some layers which are edited already. You can import the layers into the current project. To import layers means to import the edited and exported layers instead of adding and to display the layers in the map window. The imported layers will be displayed as the settings you saved. To import the layers, firstly right-click Layers in the table of contents, click Import Layer File, and choose the layer file (*.slr) you want to import. Click Open, and the layers will be displayed in the map window.

SuperGIS Desktop 3.0

The file type to import or export is *.slr(SuperGIS Layer File) which records the path, settings of the layers. “slr” file records the display settings of the layers so that the exported slr file can be displayed as the settings recorded in the file. When exporting files, you can choose to export one or all the layers. Moreover, although Add Layers and Import Layers both can display the layers in the map window, Import Layers can display the layer as the edited styles. However, the layer added by Add layer might be displayed in different styles when you add the layer since SuperGIS Desktop does not record the previous settings.

4.5 Setting Map
Users are allowed to set the basic settings of the layers in Table of Contents, including the name of Layers, map comment, map unit, distance unit, map background color, layer legend, etc. That is to say, the settings in Layers Properties are used to define the display of the map rather than a single layer. There are 2 ways to open Layers Properties window:

Fist, double-click Layers in the table of contents. Or right-click Layers and click Properties.

Second, right-click on the map window, and click Properties. This way can be only used when you are not editing the layers.

4-12

SuperGIS Desktop 3.0

You can open Layers Properties window by the 2 ways mentioned above. However, the tabs might be different due to the status of editing.

While you are not editing layers, you can see General and Coordinate System tabs.

While you are editing, you can see General tab only because the coordinate system cannot be modified at the status of editing.

Setting Map Unit
SuperGIS Desktop provides the map units, including millimeters, centimeters, meters, kilometers, miles, feet, yards, inches, etc. The settings of map unit influence the accuracy of measure results. Therefore, the settings of map unit should be based on the coordinate system of the layers you add. If the layer you add is not defined with coordinate system, you need to set the map unit. If the layer you add has been defined with coordinate system and map unit, the unit of the Layers cannot be changed.

To set the map unit, firstly double-click Layers in the table of contents. Then, Layers Properties window appears.

Choose Map unit, and click OK, and the setting of map unit is finished.

Setting Background Color of the Map
While you are editing the map in SuperGIS Desktop, the default background color of the map is white. You can change the background color to meet your need. To set the color is to open Layers Properties window and click Background button.

In Symbol Selector window, you can choose the color you need and choose the symbols in the left column. Click OK and the background color of the map is changed.

4-16

SuperGIS Desktop 3.0

In Symbol Selector window, you can choose the symbols for fill. The previous example is Solid, so the color is the Foreground color and the Background color is white. However, if you choose Vertical for fill, the Foreground color is the color of the strips and the Background color is the color of the map. As the settings are finished, click OK to complete the settings.

Chapter 4 Setting and Managing Layer

Setting Coordinate System
In a project, the Coordinate System in Layers Properties window records the project’s coordinate system, projection, etc. Users are allowed to use Select, New, Edit functions to modify or edit the coordinate system. Firstly, you can click Select, and Select Coordinate System window shows up. Choose the coordinate system you need. Or you can click Browse to search a suitable coordinate system the folders.

Setting Coordinate System for the Layers is to make the layers of different coordinate systems overlaid correctly. If the coordinate system is not set, the layers cannot be overlaid automatically. However, if none of the layers are defined with coordinate systems, the coordinate system of the Layers will be meaningless.

The coordinate system of a new map is defined as Unknown, and a layer with coordinate system is added, the coordinate system of the Layers will be defined as the same the layer directly.

4-18

SuperGIS Desktop 3.0

If you are in the status of editing, Layers Properties window will not display Coordinate System tab and only display General tab.

Moreover, you can click Create in Coordinate System tab to create your own coordinate system, including the name and contents.

Besides the name, the window also contains Datum, and Projection. Datum is a mode of measuring the earth, including Horizontal Datum to measure longitude and latitude and Vertical Datum to measure elevation. The Name dropdown list provides a number of modes. Furthermore, Spheroid is used to display the three dimensional shape of the earth obtained by rotating an ellipse about its minor axis by 360 degrees. Users can choose a spheroid coordinate system in the Spheroid Name dropdown list. Meanwhile, you can set the length of Semimajor Axis and Inverse Flattening. Semimajor Axis is the half length of the major axis of the ellipse. Inverse Flattening is the inverse flattening of the ellipse. As to the projection, users can choose whether to use Projection coordinate system. Projection uses the flat two dimensional surface to
4-19

Chapter 4 Setting and Managing Layer

describe the three dimensional surface of the earth. Generally, Projection applies mathematical model to transfer the features on the surface to the positions on the flat surface. Since the earth is three dimensional, it is necessary to apply some methods to describe the map on a two dimensional surface. Therefore, after ticking Projection, you can choose the projection coordinate system in Name dropdown list.

Compared with Create, the window, Coordinate System, appearing after Edit is clicked enables users to edit or modify the current coordinate system instead of creating a new coordinate system.

Chapter 4 Setting and Managing Layer

Layer Properties Window
There are many tabs in the Layer Properties window, each of which can be used to set different properties of the layer. Take vector layer (e.g. Shp and geo) for example. The names and the functions of the tabs in Layer Properties window are: Source: users can set layer name and its path, and add comments. Display: users can set the display of layer displaying, including Visible Scale, Reference Scale, showing Map Tip or not, and Transparency. Symbology: it means the classification of data in layer. Users can set symbol type, symbol label, and symbol color. Selection: users can set whether the layer is selectable or not and selection symbol. Table: it shows how the fields and hyperlinks are set. Relate and Joint: it sets how the attribute table is related or joined with other attribute table. Label: it sets the display of the labels, such as whether to show labels or not, which field to be text label, setting font and color of text symbol.

If you are in the status of editing, the Coordinate System tab will not appear; there will be only 7 tabs in the window.

Changing the Name of a Layer
The table of contents lists all the names of the layers. If you need to modify the layer name, there are two ways: First, click the layer you want to edit in the table of contents and click the name. The text box appears and you can input the name you need.

Second, in the table of contents, double-click the layer you want to edit. Layer Properties window shows up. In Source tab, enter the name you need in Name and click OK to finish editing,

As a layer is added, SuperGIS Desktop will use the file name as the layer name in the table of contents. As a result, if the name you want to display is different from the file name, you can change the layer name in the table of contents. However, the change will not change the file name.
4-23

Chapter 4 Setting and Managing Layer

Changing the Name of Symbol Label
As you classify the data in the layer properties window, the system will regard the values as the symbol label. If you would like to modify the description, you can change the name in the table of contents. The change does not influence the data in the attribute table but only changes the label. There are two ways to change the name of symbol label: First, in the table of contents, double-click the name of symbol label. The text box shows up, and you can edit the name.

Second, double-click the layer in the table of contents and the Layer Properties window appears. Click Symbology tab, double-click the symbol label and enter the name you need. The name of symbol label is finished.

Ordering Layers
The list of layers in the table of contents is the order of the layers overlaid in the map window. The first layer is the top layer in the map window. If you add several layers at the same time, the system will automatically place the layers in the order of point, polyline, and polygon. Then, when adding a new layer, it will add the layer above all the layers. To overlay layers, you can place the layers according to the display result you need. First of all, you can click the layer you want to move in the table of contents and drag the layer to the place you want it to display. When the layer is moved completely, the map window changes the display at once.

Move the layer “area” which is at the bottom of the map.

Copying Layers
Copying a layer is to copy the layer completely, including the symbol settings, types, classification, and the path of the layer. When you need to edit the same layers in a project, you can copy the layer rather than set the layers for several times. Firstly, select the layer you want to copy, right-click the layer, and choose Copy. The layer is copied. Then, right-click Layers and choose Paste. The copied layer is pasted into Layers.

4.7 Group Layer
Group layer refers to the group composed of the layers assigned by users themselves, with which it is more convenient to edit and manage the map. If you need to manage multiple layers as a layer, you can group the layers and create a group layer. For example, you have a river layer and an irrigation canal layer, and you can group the two layers and name it Hydrology. A group layer in the table of contents acts like other layers. However, bedsides the name of the group name, it also displays the layers in the group. Users are allowed to set the properties of each layer in the group, such as visible scale, and so on. Also, you can set the visible scale of the group layer and adjust the order of the layers. If the visible scale of the group layer conflicts with the layers in the group, the system will regard as the setting of the group layer as the priority. In the following section, the ways to set and manipulate group layers will be introduced.

Adding a Group Layer
In the table of contents, right-click Layers and choose New Group Layer. A new group layer is added. However, there is no layer in the group now, so there is no data in the table of contents and in the map window.

4-28

SuperGIS Desktop 3.0

Grouping Layers
With the function, Group, you can group the layers and create a group layer to manage the layers easily. You only need to select the layers you need, right-click the layer names, and choose Group. Then, the new group layer is added and placed as the top layer in the table of contents.

You also can group multiple group layers and create a bigger group.

The layers belonging to different tiers can neither be selected at the same time nor grouped. For example, there is a layer in Group Layer A and there is another layer in Group Layer B. These two layers cannot be grouped.

Chapter 4 Setting and Managing Layer

Adding or Removing Layers from a Group Layer
You can add layers in to a created group layer to manage the layers more conveniently. Firstly, right-click Group Layer, choose Add Layer, browse and open the layer(s) in Add Layer window, and click Open. The layers are added into the group and displayed on the map.

If you would like to remove the layer(s) from a group layer, you can right-click the layer and choose Remove. The layer will be removed from the group layer directly.

4-30

SuperGIS Desktop 3.0

Adding Group Layer in a Group Layer
You can add a group layer in an existing group layer in the map and create a multi-layer group layer. Firstly, right-click the existing group layer, choose New Group Layer, and a new group layer is added into the group layer.

As the new group is created, you can add layers in the way described before. Like the following graph, the map is composed of two group layers, but the new group layer belongs to the original group layer. Therefore, in this way, you can add sub-group layers as many as you can.

4-31

Chapter 4 Setting and Managing Layer

Changing the Layer Order in a Group Layer
If you add multiple layers in a group layer at once, the system can automatically place the layers in the order of point, polyline, and polygon to prevent the layers from being overlapped by other layers. However, if you add layers later, the layer will be added at the top, which might cover the features of the lower layers. Therefore, you may need to change the layer order in the group layer to display the features clearly and completely.

Right-click the group layer whose layers you would like to order and click Properties. Group Layer Properties window appears. Choose Group tab, and you can select the layer and click the upward and downward buttons to adjust the order. Click OK to complete the settings. The map window and the table of contents will be updated.

4-32

SuperGIS Desktop 3.0

Moreover, you can adjust the layer order by dragging in the table of contents. Take the map for example. If you want to display the point layer completely, you can drag the point layer in the table of contents to the place above the polygon layer.

As the layer order is adjusted, the drawing order of the layers in the map window is updated as well. The point layer is displayed above the polygon layer.

4-33

Chapter 4 Setting and Managing Layer

Changing the Order of Layers and Group Layer
If the table of contents contains layers and group layers, users can order the layers by dragging. Generally speaking, users had better to move the group layer to adjust the order.

Take the map for example. Since the group layer is at the bottom and cannot be displayed completely. Therefore, we have to move the group layer to the top to display the map clearly.

However, if you move the layer to the position below the group layer, the system will add the layer to the group layer.

4-34

SuperGIS Desktop 3.0

As a result, we need to move the group layer to the top layer, and the map will be displayed as the style we expected.

Chapter 4 Setting and Managing Layer

Setting Visibility of Group Layer
Generally speaking, you can tick the box before the layer name to make the layer display. If you remove the tick before the layer name, it means the layer is not displayed. Similarly, if you tick the box before a group layer, it means the layers in the group layer will be displayed. If the tick is removed, the group layer will not be displayed.

In addition, you also can decide whether to display the layer in a group layer. If the group layer is ticked but the layer is not ticked, the layer will not be displayed.

SuperGIS Desktop 3.0

Setting Visible Scale of Group Layer
To set the visible scale of group layer, you can right-click the group layer, click Visible Scale, and set the current scale as the minimum visible scale or maximum visible scale. Meanwhile, you can choose Properties on the right-click menu to set the settings in Display tab.

Also, you are allowed to set the display setting of each layer. The way is the same as other layers; right-click the layer name, choose Visible Scale or Properties to set in Display tab.

If the setting of the group layer conflicts with the layer in the group layer, the settings of group layer overrides the layer in the group layer.

Ungrouping Group Layer
If you want to ungroup a group layer to make the layers be individual layers, you can right-click the group layer and choose Ungroup.

Then, the group layer is ungrouped. The layers will be listed according the previous order in the table of contents. The display of the map window remains the same.

4.8 Layer Properties
In section 4.6, Managing Layer, mainly introduces the setting of the table of contents while this section presents the detailed settings of each individual layer in the order of the tabs in Layer Properties window. What is going to be introduced first is to set the path of the layer to solve the problem of file lost caused by the change of the file saving position. You can refer to the Tools menu > Options > Use relative path name to store layer files. Then, we will present the ways to set the coordinate system of the layer to avoid setting the coordinate system layer by layer. Also, users are allowed to set the maximum and minimum scale and reference scale of layer display to view and display the map more easily. The methods to set layer symbol and selection symbol will be introduced in the section in details. The fields in the attribute table will be presented in Setting Fields and Relating and Joining Table. At last, how to set the layer label will be introduced in the section of Labeling.

Chapter 4 Setting and Managing Layer

Setting the Path for the Layer
When saving a project, SuperGIS Desktop saves the related settings of the project, such as the path of the layer. Therefore, as you open the project and the layer has been removed from the original path, the layer will not be displayed. In the table of contents, the mark in front of the layer name will be that means the layer is lost. However, you can rewrite the path in Layer

Properties window to solve the problem.

Firstly, in the table of contents, right-click the layer which is lost and choose Properties. Then, Layer Properties window shows up.

Click Source, and Setting Path window appears. Choose the file you need and click Open.

SuperGIS Desktop 3.0

Back to the Layer Properties window, click OK to make sure the Path. And the path setting is completed. The map with a lost layer(the map below):

As the path setting is finished, the map and the mark in table of contents will be displayed correctly.

4-41

Chapter 4 Setting and Managing Layer

If the layer lost is caused by the layers moved in a project (the layers are moved to the same folder), you can modify the path of one of the layer. Then, the system will be able to find the other lost layers in the same path. If the layers are found, the paths will be modified automatically.

Layer File Type
After you add layers, you can open layer properties window and view the layer type in Source tab. If the layer is read only, it will be marked in Type. The read only file can be displayed in SuperGIS Desktop but cannot be edited.

SuperGIS Desktop should be installed under Administrator account, but other users of the computer still can use SuperGIS Desktop. However, the layer or project created by Administrator can be viewed by other users but cannot be edited. This kind of layer will be displayed as Read Only as well.

Setting the Coordinate System of the Layer
*.prj file is a file recording the coordinate data. The file records the geographic coordinate system or the projection coordinate system. If the file records geographic coordinate system, the file may contain the name of the coordinate system, Datum, Spheroid, Datum Parameters, unit, etc. If the file records projection, besides the items mentioned above, the file also records the projection and parameters. When users want to change the coordinate system of a layer but do not want to set the parameters respectively, users can change the coordinate system by the ways presented in the section. Firstly, double-click the layer in the table of contents, and the Layer Properties window appears. Click Coordinate tab, and you can edit or modify the coordinate system.

Click Select, and you can choose the coordinate system you need in Select Coordinate System window. Or you can click Browse to select the coordinate file and click OK. Then, the setting is finished.

Setting the Display of Map Tip
In the Display tab in the Layer properties window, you can choose whether to tick Display Map Tip. This function is used to set the map tip of the layer rather than the whole map.

If the function is ticked, move the mouse cursor over the feature of the layer, and the system shows the data in the Primary Field, like the map below:

If the function is not ticked, move the mouse cursor over the features of the layer, and the system will not show any tip of the layer, like the map below:

No matter what type of mouse cursor you are using, you can use the map tip function. The tip will be displayed according to the field you set.

SuperGIS Desktop 3.0

Setting the Visible Scale of the Layer
The layer can not only be displayed at any scale but also at certain scale only. Therefore, even though the map is small, SuperGIS Desktop can prevent the case that the features are too small to be displayed clearly, or the map scale is too big for users to read the whole map or the other features might be ignored due to the big map scale. So, users are allowed to set the visible scale of each layer respectively. In table of contents, double-click the layer you want to set. Then, Layer Properties window shows up, and in Display tab “Show Layer at scales” is chosen by default. However, you also can choose “Don’t show layer when zoomed” and choose “Out beyond” and “In beyond” in the two dropdown lists. The lists contain the common scales, none, and current scale. None means no setting; Current Scale stands for the current scale in the map window.

Take the point layer setting for example. The minimum scale is 1:250000, and the maximum scale is 1:10000.

4-47

Chapter 4 Setting and Managing Layer

To set “Don’t show layer when zoomed”, you can only set one of the conditions If the scale is between 1:10000 and 1:250000, the layer can be displayed completely.

If the scale is smaller than 1:250000, the layer is not visible.

4-48

SuperGIS Desktop 3.0

If the scale is larger than 1:10000, the layer is invisible, either.

In addition to the way describe above, you can also right-click the layer in the table of contents, choose Visible Scale and set minimum/maximum scale here. The system will set the minimum/maximum scale according to the current scale of the map.

4-49

Chapter 4 Setting and Managing Layer

Moreover, after you set the minimum/maximum scale of a layer, the mark in front of the layer will become when the map scale is beyond the visible scale. As the grey check is displayed, you

still can uncheck the layer and make it invisible.

SuperGIS Desktop 3.0

Setting the Reference Scale
The reference scale might affect the display of features when the map is zoomed in/out. If you have set the reference scale, the features will be bigger when the map is zoomed in; the features be smaller as the map zoomed out. Right-click Layers in the table of contents, choose Reference Scale in the menu, the system will set the reference scale based on the current scale of the map. If you want to clear the reference scale, you can also apply the menu and choose Clear Reference Scale.

After you set the reference scale, the features of different types of layers might be influenced in different ways. In the polygon layers, the boundaries of the polygon features will be wider or thinner as the map is zoomed in/out. The width of the line features will be influenced by map scale. The size and the width of boundary of the point features will be affected by the map scale as well. Take the map for example. If the reference scale is not set, the lines are not influenced when the map is zoomed in.

4-51

Chapter 4 Setting and Managing Layer

If the reference scale is set, the lines become thinker or thinner when the map is zoomed in/out.

Besides the methods above, you can open Layers Properties window to set the reference scale.

The map scale will not appear

when your map is not defined with map unit.

So, the settings related to scale, such as “Don’t show layer when zoomed” and reference scale will be disabled if there is no map unit.

Setting Symbology
The common vector layer types include point, polyline, polygon, and multipoint. The feature symbols in different types of layers can displayed more various and clearly by classification to present the information of the map. To set layer symbology, you can right-click the layer, choose Properties to open Layer Properties window. In Symbology tab, you can choose the symbol type you need according to the type of the layer.

The types of the layer symbol include the following types: 1. Single Symbol: regards all the attributes of the layer as a classification and displays the data with a single symbol. 2. Graduated Color: classifies the quantitative data and displays the attributes with graduated colors to present the quantitative data.

3.

Graduated Symbol: classifies the quantitative data and displays the attributes with different sizes of the points.

4. 5.

Unique Values: displays the different attributes with different symbols and colors. Unique Values (multi-fields): displays the attribute combinations of multiple fields with different symbols and colors.

6.

Pie Chart: to display multiple numeric fields of a layer with pie charts. Users can know the percentage of the attribute value of each feature and compare the pie charts.

7.

Dot Density: displays the quantitative values of the features with the distribution of dots. You can know the quantities by reading the distribution of the dots. The symbol can only be applied to polygon layer.

8.

Bar Chart: displays the multiple numeric fields of a layer with bar charts. Users can read the data of different fields at the same time and also can compare the bar charts.

SuperGIS Desktop provides different symbol settings for different types of layers: 1. Point layer: point size, rotation, offset, fill color and style, outline, etc. Users are allowed to import their own symbol icons. 2. 3. Polyline layer: line styles, color, width, transparency, whether to use anti-alias or round pen. Polygon layer: fill styles, color, and outline styles.

In this section, the 8 types of symbols will be introduced and the ways to set will be presented in details as well.

Unique Values
The method is to classify attributes of a specific filed (including text field and numeric field). Each category is assigned with different color and style of symbol. You can utilize Unique Values to present your map when:

1. When the characters of the features are similar, and you want to see how the features are
distributed.

2. The attributes of the features are different but the relationship between each other is
meaningful.

3. Or to contrast the categories is also suitable for the unique value map.

The column Label next to Value is displayed in the table of contents, too. So, you are allowed to double-click the label in the Layer Properties window to edit it. Or you can double-click the text in the table of contents to edit the text. Additionally, the Count beside Label refers to the count of the features of the symbol. If you tick Show Others, the map window and the table of contents will show the classification of Others. If the item is not ticked, the classification will not be displayed in the map window or the table of contents. As all the settings are finished, click OK and the unique value map is completed.

The symbol colors, styles which are set completely can be saved by clicking the Save button on the upper-right corner of the tab; the settings will be saved as*.sgl(SuperGIS Legend Files) format in the assigned folder. The default filename is Legend. Next time when you need to use the same classification, you can directly click Load button on the upper-right corner of the tab to load the file instead of setting the symbols again.

After choosing the fields, you can click Add All Values or Add Value to add the value by clicking. Then, click OK to add the value. Also, you can enter the value at the bottom of the window and click Add to add it. Therefore, the system will be able to classify the value when you add the new values.

If you click Add All Values and there are more than 500 records of the classification, the system will show the warning message automatically to ask whether you want to add all of the values. If you click NO, the system will add the first 500 records of the field only.

Graduated Color
When you need to display the map quantitatively, you need to choose graduated color or graduated symbol to classify your map. The former uses different polygon symbols to present different attributes, and it is called Graduated Color map. Graduated Color is to use a series of colors to stand for the values in different ranges. Generally, the attributes are categorized by ranges, such as 0-5, 6-10, or from the lowest to the highest. Therefore, the classification method is only suitable for numeric field. The following map is the geology classification map of Northeast Coast of Taiwan. Each color presents a range of layer count. The deeper the color is, the more the layers are. Each range contains 10 layers and is presented with a color.

Chapter 4 Setting and Managing Layer

To set the graduated color, choose graduated color in the dropdown list in Layer Properties window; then, graduated color settings appear. You can choose the field for classification and decide whether to use Normalization dropdown list. You can choose the filed for Normalization with which you can normalize the values in Value Field; the results will be classified. The item is optional (the default is none). For example, if you want to calculate the population density, you can choose population in Value Field and choose area in Normalization. As a result, the system will divide the population by area, and you will get the population density. The results will be classified. Moreover, you can decide the classification classes in the Classes dropdown list (you can enter the value directly as well). In Color dropdown list, choose the gradient colors you need. The range of the classification can be modified; users are allowed to double-click the range column and enter the value to modify the maximum of the range. Take the first row of the table for example. The original range is 21~31; if the range is modified as 21~35, the second row will be 36~41. So, the problem caused by range modification can be prevented. The Label column next to Range can be modified in the same way, but the modification only affects the display in the table of contents rather than the range of classification.

4-66

SuperGIS Desktop 3.0

Click the Classify button next to Class, and Classification window shows up. There are four methods for classification, Equal Interval, Quantile, Natural Breaks, and Defined Interval. Equal Interval is to subtract the minimum from maximum so the result will be the scope of the classification. According to the count, the scope is divided to equal interval. It is probably best applied to rainfall, temperature, air pollution, etc. Quantile is to divide the range of possible values into unequal-sized intervals so that the number of values is the same in each class. Natural Breaks is to sort the all values and then count the interval of each other. According to the count of classification, choose the max interval first and classify the all values. Defined Interval lets users define the interval by themselves. So, Defined Interval is chosen, and users need to enter the interval.

As all the settings are finished, you can click OK to complete the graduated color settings. The ways to manipulate the other buttons in the tab can be refereed to the introduction to Unique Values.

After the classification is decided, the system will classify the data based on the settings. The classification is based on the range of maximum and minimum. In addition, Value Field only lists the numeric fields in the attribute table. The fields which are not numeric will not be listed in Value Fields.

Graduated Symbol
When you need to quantify the attributes of the map, you can use the graduated color or graduated symbol to classify your map. The latter represents the different quantities by varying the symbol size; that’s what we call the graduated symbol map. Graduated symbol uses a series of symbols to present the numbers in different ranges. Generally, the attribute values are classified to ranges or intervals, like 0-5, 6-10, or from the lowest to the highest. For instance, the map bellow shows the area size of parks in Taipei with the dots of different sizes. Each interval is 10,000 m2 and presented with a symbol of the specific size.

To set graduated symbols, choose Graduated symbol in Symbol dropdown list in Layer Properties window. Then, choose a field for Value field. In Normalization, you can choose whether you need to divide the value field by any field. If no, you do not have to choose the normalization field (the default is none). Then, click the Classes dropdown list and choose the classes you need (you can directly enter the value).

The color, style of the graduated symbols can be modified respectively. If you want to modify all of the symbols, you can click to modify them. In addition, at the bottom of the window,

users can input the symbol size by themselves (the default is from 5 to 20) and the system will set the symbol size according to the settings.

Setting Fields
Field tab in Layer Properties window lists the details of the fields, including name, type, length, precision, etc. In the tab, users can set Primary Field and Hyperlink Field. Primary Field is the field whose data will be displayed in the left column in Edit Attribute window. The default primary field is assigned by the system; the field name containing “name” will be the priority. Take the graph for example. The primary field is TOWNNAME so that the data displayed in the left column of the window is the attribute in TOWNNAME field.

The Hyperlink field dropdown list shows the name of the fields. You can choose a field which records the websites or paths of files. A feature can correspond to more than one hyperlink. To set the hyperlink, firstly open the attribute table, enter the hyperlink in the cell or right click the FID field of the feature you want to add hyperlink to and choose Add Hyperlink.

Relating and Joining Table
The Relate and Join tab in Layer Properties window enables users to relate or join the attribute table with other attribute table. Relating tables is to relate the common attributes of the two layers and make the relationship. So when you identify features of one of the layers, the identify window will not only show the data of the feature recorded in the layer but also the data of the feature recorded in the other layer. Moreover, Joining tables is to join two layers’ tables based on a specified attribute field (the fields’ properties must be the same, while the field name and the order of attributes are not necessary the same). The system joins the target table to the source table according to the specified field. The target attribute table will be joined to the source table according to the assigned fields, which will create a new attribute table. Joining table can be also applied to feature identification. While users are identifying features, the corresponding attributes will also be displayed in the identify window. Furthermore, the joined attribute table can be exported as well. First of all, to set Relate, both of the two layers, POI and School, contain the features whose attribute is “school”, so you can right-click POI layer in the table of contents and choose Properties. In Relate and Join tab in Layer Properties window, click Add in Relate. Relate window shows up. Choose a field in Source Field and choose a table and its field in Relate Target. You can enter a name in Name or maintain the default name. If the layer you need is not in the Table list in Relate Target, you can click Open to choose the file you need (SuperGIS Desktop 3

supports Excel table as the relate target). Then, click OK to finish the settings.

Labeling
The last tab, Label, in Layer Properties window allows users to set the display of labels and the styles of labels. First of all, if you want to label the features on the map, please tick Show Label. In Text Label dropdown list, you can choose the field whose attribute value you want to display. Field dropdown list contains all of the field name and “expression.” Therefore, the label can not only be the values in the attribute table but also the results of expression. The field dropdown list defaults to the field whose name containing “name.”

In addition, you can set the font, color, and even transparency of labels in the tab. Moreover, the tab also allows users to set the label duplication and conflict detection. Considering the readability of labels, you can click Visible scale button to set the visible scale of labels. Furthermore, according to the type of layers, users can set the placement of label in different ways. The methods to label features of different types will be introduced in the following section.

As you are setting the expression, you can click the buttons at the bottom of the window. Clicking Clear can clear the expression you have input. Clicking Load can load and use the saved expression. If you want to save the expression in the assigned folder, you can click Save button. And you will be able to use the expression by Loading. Also, users can click Verify button to preview the results of expression, like the window below.

Duplication There might be some labels with the same contents on a layer or features combined with multipart features. To display the map clearly, you can make the label display according to your needs. You can choose the way to display labels in Duplicate Labels.

Remove duplicate labels There might be some features with the same labels on a layer or within some area. In order to improve the readability of map and have enough space for other labels, you can set Remove Duplicate Labels. As a result, only one of the duplicated labels will be displayed. The system will display the label recorded firstly in the attribute table,

Chapter 4 Setting and Managing Layer

Place one label per feature If your map contains multipart feature, you can choose Place One Label Per Feature. So, only one label will be displayed on the multipart feature. For point multipart features, the first drawing point will be labeled. For polyline multipart features, the longest one will be labeled. For polygon multipart features, the biggest one will be labeled.

Place one label per feature part To display all the label of each part of the multipart features, you can choose Place One Label Per Feature Part. Then, all parts of the features will be labels.

Conflict Detection
The labels on the map might be overlapped since they are too closed. You can set No Overlapped Labels and Buffer Ratio of Label Height in Conflict Detection to prevent the labels from being overlapped.

Take the lower-left map for instance. The labels are so closed that some of the labels are overlapped. So, you can tick “No overlapped labels,” and the system will automatically adjust the display of labels and hide some of the labels.

4-94

SuperGIS Desktop 3.0

As “No overlapped labels” is ticked, you can also set “Buffer ratio of label height” which is set by the label height. So, each label will be buffered with the ratio and the labels will not be overlapped. The lower-left map shows the labels as the original display; the lower-right map is the result of “buffer ratio of label height” 0.5.

Setting Visible Scale
After the Text Label Field is set completely, you can click Visible Scale button to set the visible scale of the labels.

Chapter 4 Setting and Managing Layer

If you choose “Same as layer’s visible scale”, the display of labels will be the same as the visible scale of the layer. If the layer is defined with reference scale or visible scale, the display of labels will be changed according to the layer.

However, “Don’t show label when zoomed” is ticked, the size of the labels will not changed and only displayed at the specific scale. Take the map for example. The display of the label of the layer is set that don’t show the label when zoomed in beyond 1:100,000,000. The left map is at the scale of 1:117,074,879 so that the labels are displayed. The right map is at the scale of 87,761,157 so that the labels are not displayed.

You do not have to set the labels first but label the features on the map first. You can zoom in/out the map to check the suitable scales of label display and then set the visible scale of labels.

Setting Label Placement As to the setting of label placement, users can set the placement, angle, display priority of the labels, etc according to the style, shape, characteristic of the features. You only need to click Placement button, and the system will open the setting window based on the type of features.

If “Place label horizontally around the point” is chosen, you can set the priority of the display position by clicking. 1 means the first priority position for labeling, 2 is the second, 3 is the last position for labeling. 0 means the position is never used. In the blocks, you can click to make the digit bigger and right-click to make the digit smaller. The number should be between 0 and 3. The labels on the right map are displayed based on the left settings. Clicking Default can make the priority settings reset.

If ”Place label on top of the point” is chosen, the label will be placed on the point feature.

If you choose “Place label at an angle specified by a field”, you can click the dropdown list and choose the field recording the angles. Click OK, and the labels will be placed according to the angles on the map.

If the labels are overlapped at the first angle, the system will automatically place the label at the second angle, and so on. Furthermore, you can choose the orientation, Geographic or Arithmetic in Point Placement window.

Line features The line features on the map may stand for street, subway line, river, and even contour. Line features with different meanings need labeling in different ways. In SuperGIS Desktop3, you can label lines in various orientations and on several positions. To label street names, for example, you may want the labels paralleled to the line features. To label subway station, you might need to place the label perpendicular to the line features. Therefore, you can click Placement button in Layer Properties window to open Line Placement window to set the orientation and position of the labels.

Setting Image Display
In GIS, layers can be divided into two types vector layer and raster layer. In the previous sections, we mainly introduce the ways to display and manage the vector layers, such as point, line, and polygon features. As to the settings of the raster layer, we will introduce the manipulation in the section. Since the raster layer might be single band data or multiple bands data, you can adjust the display of the layer by changing the display type and display band. The Layer Properties window of raster layer is a little different from the vector layer, only containing source, coordinate system, display, and image tabs. Since Source and Coordinate System tabs are the same as the vector layer, the manipulation will not be introduced in this section. This section only presents the settings of Display tab; the next section will introduce the image tab.

4-104

SuperGIS Desktop 3.0

Firstly, if you want to set a raster layer, please right-click the raster layer in the table of contents and choose Properties. In Layer Properties window, choose Display tab in which you can decide whether to tick Show Map Tip.

Meanwhile, users are allowed to set the visible scale of raster layer as well. Since a raster layer might be overlaid with other layers, you can choose to display the layer at all scales or only at a specific range of scales. As a result, it can avoid the raster layers from displaying unclearly caused by the map scale.

Resample Method
When the raster layer is overlaid in a different coordinate system or different resolution, the raster layer needs to be resampled. It might need a pixel of the rater data to replace a group of pixels or need a group of pixels to replace a pixel. Therefore, the resampled image might be rougher than the original image.

In Display tab of Layer Properties window, there are 3 resample methods provided, such as Nearest Neighbor Resampling, Bilinear Interpolation, and Cubic Convolution. Nearest Neighbor: In the process of resampling, the resampled image might correspond to the
4-105

Chapter 4 Setting and Managing Layer

non-integer when the output image corresponds to the input image. In order to calculate the values of the cells, the value will be calculated from the nearest neighbor cells of the input image. Therefore, the method does not change the value of the cells of the input layer; meanwhile, it is the fastest way to resample and often used for categorical data and thematic data Bilinear Interpolation: it is a resample method to use four nearest cells to calculate a new value. Since the value is the weighted average of four nearest cells, the image process with the method will be smoother then with Nearest Neighbor. Cubic Convolution: Similar to Bilinear Interpolation, Cubic Convolution uses the weighted average of nearest 16 cells 和 to calculate a new value. As a result, the output image is calculated by more cells and the image processed with Cubic Convolution is clearer than with Bilinear Interpolation. The latter two methods are often used for continuous data, like height, slope, and so on. Consequently, you can choose the resample method suitable for you in Resample Method dropdown list and click OK. The resampled image will be displayed in the map window. The following pictures are the samples processed with different resample methods.

Setting Transparency, Contrast, and Brightness
If the image is too dark or too bright, the display effect might be affected. Or you would like to display the image with other layers, you can adjust Transparency, Contrast, and Brightness to set the display effect. The way to adjust the settings is to right-click the layer which needs adjusting and click Properties to open Layer Properties window. Choose Display tab, and you can enter the value or drag the trackbar to adjust the settings. When the settings are completed, click OK to close the Layer Properties window. And the result will be displayed in the map window.

Take the map for instance. The map contains several layers, including raster layer and vector layers. You can adjust the transparency of the raster layer and make the layers below the image be displayed at the same time. In the left map, the image is set as 0 % transparency so that the layers below the image are covered. The right map contains the layer with 30 % transparency, so you can see the orange and blue features with the image. If there is no layer below the image, adjusting the transparency of the image can reveal the map background color.

Setting Image Properties
The display of image is decided by the data contained in the image and you own needs. Different types of images can be displayed in different ways. For multi-band images, you can choose RGB Color or Stretched Color. Single-band image can be displayed with Stretched Color, Graduated Color, and Unique Value. No matter which display type you choose, the images should be stretched, rendered, etc. Thus, the related settings will be presented in the section. Firstly, open the image layer’s Layer Properties window and choose Image tab in which you can set display type, band, stretch, add new color ramp, view histogram, etc. What is going to be introduced first is RGB color in Display Type.

4-110

SuperGIS Desktop 3.0

RGB Color
If your image is multiband, you can choose to display with RGB Color. Please choose RGB Color in Display Type in Image tab.

After RGB Color is chosen, in Bands, you can tick the band, red, green, and blue to decide whether to display. Meanwhile, you can set red, green, blue to be displayed in which band. Below Bands, there is a Stretch Type dropdown list, including none, minimum-maximum, histogram equalized, standard deviation, and custom.

None: If you cannot make the image stretched, you can set the maximum and minimum to decide the range of stretch. The range of pixel of an 8-bit image file is between 0~255, and that of 16-bit one is between 0~65535. Minimum-maximum: The system will stretch the color of the original layer via interpolation to the range you set. Histogram Equalized: It’s an image contrast enforcement technology by hiding the subtle part of an image to the light and dark ends of the spectrum. It can strengthen the contrastive effect.
4-111

Chapter 4 Setting and Managing Layer

Standard Deviation: The system calculates the standard deviation of the pixel value of each band automatically. If you set 1 on “n”, the system will add and subtract one standard deviation to the average as the range of the stretched color. If the number of standard deviation you set causes the stretched range over the range of the original pixel, the system will still do stretch according to the original range. Because the system sets the range of stretched color by adding and subtracting n standard deviation. The smaller n is, the smaller the stretched range and the greater color contrast then obtained. If n is bigger, the result will be the contrary. Custom: You can adjust or add breakpoints to set the range of stretch.

Moreover, the Image tab also provides Inverse Color and Display RGB functions.

4-112

SuperGIS Desktop 3.0

If Inverse Color is ticked, the image will be displayed as the inverse colors, like the image below: Original image Image with inverse color

If Display RGB is ticked, you can define a cell of specific values as No Color or a specific color. As a result, the system will automatically replace the cells of the specific values with No Color or the assigned color. It would be easier for users to edit and view the image. No Color means the cell is transparent so that the color of the lower layer or the map background color will be revealed. Take the lower-left image. We set the cell R:176 G:194 B:199 as dark blue, and the image will be like the lower-right image.

Moreover, if Display RGB is chosen, you are also allowed to set Display NoData as No Color of a specific color. No Color means the cell is transparent so that the color of the lower layer or the map background color will be revealed. In the lower-left map, the map background color is blue so that the NoData cell will be displayed as blue. If you set Display NoData as red, the map will be like the lower-right image.

Chapter 4 Setting and Managing Layer

When the image layer is added in SuperGIS Desktop for the first time, a HST file recording the image data will be created. As the HST file exists, the stretch method is Standard Deviation, n=2 by default after the image layer is added in SuperGIS Desktop.

4-114

SuperGIS Desktop 3.0

Stretched Color
Stretched Color can be applied to multiband images and single-band images. In terms of multiband image, choose Stretched Color as the Display Color in Image tab first, and define the bands you would like to display. Then, choose a stretch type from none, minimum-maximum, histogram equalized, standard deviation, and custom.

If you choose Minimum-maximum, you may need to enter the values for minimum and maximum. The label of maximum and minimum will be changed according to the values you set.

4-115

Chapter 4 Setting and Managing Layer

If you choose Standard Deviation, please set the number of standard deviation in “n.” For example, you enter 1 and the system defines the range of the stretched color by adding and subtracting 1 standard deviation to the average (the default n is 2). Then ,you can click Histogram button to see the distribution of the colors. If you choose Custom as the stretch type, the Histogram window will show up automatically. In the histogram, you can add or drag the breakpoint to set the distribution of the colors.

After the color stretch settings are finished, the image should be colorized. Choose the color in Color dropdown list to decide the colors displayed on the map. If Inverse Color is chosen, the image will be displayed as the inverse colors. If “Display pixel value as” is chosen, you can enter the values to assign the color to be displayed as No Color or an assigned color. Meanwhile, you can set “Display NoData as” NoColor or an assigned color. As the settings are completed, click OK to close the window.

Graduated Color
Graduated Color can be applied to single-band image and can display the image as different colors based on the “classes” you set. This method is often used to display the image with the continuous data, such as slope, distance, and so on. Different from RGB Color and Stretched Color, Graduated Color does not stretch the colors but can classify and colorize the colors directly. Take the map for example. The colors are between -8 and1735; you can set the color and classes after you choose Image tab and Graduated Color. Thus, the system will automatically classify the colors.

Adding Gradient Color Ramps
Gradient Color Ramps are used quite often no matter you are working with the features in vector layers or raster layers. If the gradient color ramps built-in SuperGIS Desktop 3 cannot meet your needs, you can add the gradient color ramps by yourself to make your project displayed in a unique way. The method to add a gradient color ramp can be applied to raster layers and vector layers so that we take a raster layer for example. Firstly right-click the raster layer in table of contents and choose Properties. In Layer Properties, choose Image tab and right-click the color ramp. Then, choose New Gradient Color Ramp on the menu.

No matter in Symbology tab of vector layer or in Image tab of raster layer, as long as there is a Color item, you can follow the steps described in the section to add New Gradient Color Ramp.

As the New Gradient Color Ramp window is open, you can click

to display Color window. In

this window, you can choose the color from Basic Colors or chose Custom Colors to choose the color you need. As you choose a color, the chosen color will be added to New Gradient Color Ramp window.

Repeat the steps described above, the color ramp will be added to the window by interpolation. Also, you can click and to adjust the order of the colors; or you can click to

remove the color. If you have finished the setting, click OK to close New Gradient Color Ramp window.

SuperGIS Desktop 3.0

As a result, you can see the new gradient color ramp in the Color dropdown list. The new gradient color ramp will not only appear in the dropdown list but also in other dropdown lists in other layers.

If you added a new gradient color ramp in a project and open the project in another computer, SuperGIS Desktop in the computer will apply the new gradient color ramp to the system. Therefore, even your project opened in another computer, the map can be displayed as the original settings.

Adding Step Color Ramps
Besides adding gradient color ramps, you also can add step color ramps. Like adding gradient color ramps, right-click the raster layer in table of contents and choose Properties. In Layer Properties, choose Image tab and right-click the color ramp. Then, choose New Step Color Ramp on the menu.

4-121

Chapter 4 Setting and Managing Layer

New Step Color Ramp window appears. In this window, there is a HSB palette. You can drag start value and end value to define the range of the colors. The system’s principle of choosing colors is to choose the color from the start value to the end value counterclockwise and randomly. To set Hue, you can adjust the range of palette by dragging or adjusting in Start and End. Similarly, you can set the start and end values in Saturation and Brightness.

Every time you modify a value in the previous steps, the system will change the step color ramp again. The colors in the color ramp are decided by the ranges of hue, saturation, and brightness. If you are not satisfied with the color ramp, you can click Reset and the system will choose the colors again randomly but based on the values you set. You can click the button repeatedly until the generated color ramp satisfies you. As the new step color ramp is created, click OK to close Add Step Color Ramp window. Then, you can see the new step color ramp in Color dropdown list. The new step color ramp will not only appear in the tab but also other dropdown lists of other layers.

Histogram
Click Histogram button in Image tab in Layer Properties window, and the Histogram window appears. The window shows the related data of cells of the raster layer. No matter you choose RGB Color and Stretched color as the display type of the raster layer, the Histogram window can be opened when minimum-maximum, standard deviation, and custom are selected as stretch method. The lower-left graph is a histogram of multi-band image; the lower-right graph is the histogram of single-band image. For multi-band images, the histogram window contains 3 tabs to present each band, while the histogram of single-band image displays the distribution of the color of the image. Statistics field on the right side records the data of the cells of the band, such as min, max, average, standard deviation. Meanwhile, you can move the mouse cursor around the histogram to check the value and the count of the value in Input and Output in Information field. The X axis refers to the color of the input image, so the range is from 0 to 255. The Y axis is the color of the output image, so the range is also from 0 to 255.

The grey part in the histogram is the value distribution of the input image, while the output image is displayed in other colors (like dark red, green, blue). In the following graph, due to the histogram of single-band image, the distribution of the output image is displayed as dark red. Meanwhile, you can move the mouse cursor around the histogram to check the count of the cells in the input image and the count of the value which is changed by the settings of the output image. In the lower-left graph, the current cursor poison shows that the color 190 in input image posses 0 cell but possess 831 cells in output image. If you would like to know the new value generated by adjusting the line, you can move the mouse cursor to the X coordinate of the value in the input image and move the cursor to the line, the Y coordinate in lower-right corner of the window indicates the new value generated by adjusting the line.

Editing
5.1 Editing Features 5.2 Editing Attributes
As users create a new map or make changes to the features on the map, users need to use the editing tools. SuperGIS Desktop 3 can facilitate users to easily add, move, copy, paste, delete features and even to edit vertices and attributes. The main goal of the chapter is to introduce how to edit the features and attributes on the map with SuperGIS Desktop 3, and the manipulation of editing functions are introduced as well. The chapter can be divided into two parts, “Editing Features” and “Editing Attributes.” In “Editing Features,” the buttons on Edit toolbar and the functions in the drop-down lists will be introduced; the effects resulted from each editing tool cooperating with editing modes are going to be presented, too. Moreover, this chapter will also introduce how to edit the vertices of the features. Also, the ways to edit attribute table and attributes of each feature will be presented in “Editing Attributes.”

Chapter 5 Editing

5.1 Editing features
This section will mainly focus on editing features, including points, polylines, and polygons. First, the buttons and drop-down lists on Edit toolbar will be introduced; then, the functions and settings users need to apply in editing will be presented. Meanwhile, we will instruct the techniques for adding point, polyline, polygon features with editing tools. In addition, some functions users need frequently, such as delete, move, copy, and paste, etc will be introduced in this section, too. Editing vertices and adding new features with existing features are going to be described in the section as well.

The way to open Edit Toolbar is to click Tools menu and Customize. Then, tick Edit in Toolbars tab in Customize window and click OK. Or, you can right-click a toolbar on the map window and tick Edit. Then, Edit Toolbar is added.

Start Editing
Start Editing is the leftmost button on the Edit Toolbar. Before users start to edit the

features on the map, users have to click Start Editing. After clicking “Start Editing,” you can select features and edit the selected features with the buttons on Standard Toolbar, Cut, Copy, Paste, and Erase . If you would like to stop or save the editing, you can click the

drop-down arrow next to “Starting Editing” and click End Editing or Save Edits. When you are

using Copy and Paste, please pay attention that the new feature will exactly cover the original one. Therefore, you need to move the new feature with mouse to the desired location. Moreover, the other tools, like Move to, Offset, Rotate, etc will be introduced in detail in “Advanced editing tool”; Snapping will be introduced in “Start Edit.”

Edit Target
Since a map is composed of several layers, and features with different geometry types belong to different Target layers, you may need to check the type of the target layer in Edit

. Some tools must be applied in specified layers, such as

Adding Features. Thus, you can only add the feature whose geometry type is the same as the layer in Edit Target. For example, if the layer in Edit Target is a point layer, you can only add point features in the point layer rather than polyline features or polygon features. The editing results will be saved in the target layer. However, some tools can be used without geometry limitations. In this case, you can select and edit a feature on the map, and the result will be saved in the original layer. If the tool you are using cannot be implemented in the target layer, the warning window “The features cannot be copied to the target layer with wrong geometry type” will be displayed.

Select Features Tool
After clicking “Start Editing”, “Select Features” tool will be selected automatically. Then,

you can click the feature you would like to edit and make changes to it. If you select “Add New Features” or other editing modes, you still can use “Select Features” tool to select and edit features at the same time.

Editing Tools
When you need to edit features, you can select “Editing Tools” on Edit toolbar, click the

drop-down arrow, and select the tool you need. The editing tools provided by SuperGIS Desktop 3 include Sketch Tool , Midpoint Tool , Nearest Distance Tool , Rectangle Tool ,

Circle Tool

, each of which may be applied to different geometry types and functions. The

editing tools cooperating with various editing modes, such as adding new features, cut features, etc, can produce different effects. Thus, this chapter is going to introduce the methods to utilize the editing tools with editing modes in detail.

The basic manipulation of editing tool is introduced briefly in this section. The method to use Sketch Tool is to click on the map window, move the mouse to sketch, and double-click to finish sketch (or right-click and click Finish Sketch to complete the current action). Besides, Midpoint Tool can facilitate users to create a point at the middle of a line segment; you can click to set the first point of the line segment and click again to set the other point, and then the midpoint is added. If you would like to use Midpoint Tool to create a line or polygon, you can repeat the actions described above and double-click the last vertex or right-click and click Finish Sketch on the menu to finish the sketch. Moreover, when you want to edit a nearest distance between a vertex and a line segment, you can apply Midpoint Tool. When you utilize Midpoint Tool to sketch line features, the first vertex is the midpoint of the line segment you sketch. Then, you can sketch
5-5

Chapter 5 Editing

another line segment, and the next vertex will be the point of vertical intersection of the last vertex and the line segment. And you can repeat the movement until the line feature is finished. The way to end the sketch is the same as other editing tools. Rectangle Tool and Circle Tool are similar; the difference is the shape created. You can select Rectangle Tool or Circle Tool, click on the map window, drag a rectangle or a circle, and click again to finish the sketch.

Editing Modes
Several editing modes are provided in SuperGIS Desktop 3 for users to choose as necessary. Editing modes include Add New Features , Modify Features , Cut Features ,

Extend/Trim Features

, Mirror Features

, Auto-Complete Polygon

, Select Features by

Polyline

, and Select Features by Polygon

. Add Features can add point, polyline, or

polygon features according to the editing tools and the layer you choose. Modify Features is able to edit the vertices of features with the editing tool users select; Cut Features can cut polyline features and polygon features. Moreover, Extend/Trim Features can only change the length of polyline features, so it has no effect on point features or polygon features. Meanwhile, Extend/Trim Features changes the length of features in different ways by using various editing tools. Mirror Features can create a mirror image of selected feature(s) on the other side of the line you create; the tool can be applied to create streetlights or buildings on the roadside. All you need to do is create or select feature(s) and sketch a line segment with Mirror Features, and the new feature(s) will be added. Furthermore, there must be lots of common boundaries of polygons when you sketch street blocks, territories, districts, etc. You can use Auto-Complete Polygon tool to avoid that the polygons do not share the boundaries with other existing polygons. In addition, Select Features by Polyline tool can select the features intersecting the line segment you construct; Select Features by Polygons tool can select the features intersecting the polygons you construct. Users can use the two modes with each editing tool to select features.

SuperGIS Desktop 3.0

Since the effects produced by each editing mode and editing tool are complicated, the manipulations and effects will be introduced in detail in the next section.

Other Tools
In addition to the editing tools discussed above, the Edit Toolbar contains other tools else, such as Split Tool , Separate Parts , Rotate , Edit Attributes , Edit Geography .

Split Tool can split a polyline feature into two parts. Split Tool can be used only when one polyline feature is selected; the tool does not work as more than one polyline features selected. Separate Parts can be used to separate multipart features, including points, polylines, and polygons. Another tool “Rotate” can rotate features; you can select a feature and Rotate tool, then move the mouse cursor over the selected feature, click and drag the feature to the desired orientation. Then, the orientation of the feature is changed. Besides, if you would like to edit the attributes of some feature, you can select a feature and click Edit Attributes to display Edit Attribute window. You can click the values and enter the values in the window directly and click the upper-right of the window to finish editing. When you have selected some feature, you can click Edit Geography tool to display Edit Vertex window in which all the coordinates of the vertices are recorded. If you click some record in the window, the vertex will be displayed as white on the map window. Moreover, you can double-click the coordinate column in the window and enter editing status, and you can enter the values directly. After finishing editing, click Finish Sketch on the lower-right corner of the window.

Introduction to Editing Environment
The editing environment provided by SuperGIS Desktop 3 applies cache to temporarily duplicate the data rather than save the data into original files. Therefore, the process can avoid data disappearing caused by computer crash or running out of battery. Only if you click Save Edits in the drop-down list of the Start Editing, all the edits will be saved into the original files. Additionally, the file formats supported in SuperGIS Desktop 3 include GEO File and Shape File; if other formats, such as dgn and mif are added in, this map can be displayed but not editable. However, if you add read-only GEO File or Shape File, the editing functions still cannot be used; read-only layers are not listed in Edit Target, either. Due to GEO File and Shape File supported, when users add new layers, there are 7 types of layers provided to add new layers. Users can choose the suitable layer type and coordinate system.

As the coordinate system is set for “New Layer,” the system will create a corresponding prj file for this layer.

Select Features by Polyline
The principle of Select Features by Polyline tool is to select all of the features intersecting the line segment you sketch, except point features. Take the map for example; a line segment is sketched in order to select all the features intersecting the line (Graph 1). After users right-click and click Finish Sketch or double click to finish the sketch, the features intersecting the line are selected (Graph 2), but the point feature is not selected. Similarly, if you use Rectangle tool or Circle tool with Select Features by Polyline tool to select features, the features intersecting the boundary of rectangle or circle will be selected, except point features. Graph 1 Graph 2

Select Features by Polygon
When you would like to select all the features in a certain area, you can use Select Features by Polygon tool with various Editing Tools to create a polygon and select the features by the polygon. You can choose suitable editing tools, such as Sketch Tool, Midpoint Tool, and Nearest Distance Tool, to sketch polygons (Graph 3). After you finish sketching (right-click and click Finish Sketch or double-click to finish the sketch), the features intersecting the polygon will be selected (Graph 4). Similarly, you can use Rectangle Tool or Circle Tool to create a rectangle or a circle to select features, and the features intersecting the rectangle or the circle will be selected. Graph 3 Graph 4

Finish Sketch can be used in selecting features and adding features to end the current sketch.

If you would like to zoom in the selected feature and zoom to the full extent of the map, you can select Select Features Tool and right-click the map, click Zoom to Selected Features. Then, the selected features will be zoomed in and to the full extent of the map. Moreover, you can right-click the layer the selected features belong to in Map Content Window, point to Selection and click Zoom to Selected Features. If the features you select include multiple types of features and you only want to zoom in some certain type of features, you can right-click the layers this type of features belong to in Map Content Window, point to Selection and click Zoom to Selected Features. Then, the features belonging to the certain type will be zoomed in and to the full extent of the screen.

Pan to Selected Features
After selecting features, if you want to move the selected features to the center of the map window, you can click Select Features tool, right-click on the map window, and click Pan to Selected Features. Then, the selected feature(s) will be displayed at the center of the screen with the same scale. Besides, you can also right-click the layer the selected features belong to in Map Content Window, point to Selection, and click Pan to Selected Features. If the features you select include multiple types of features and you only want to pan some type of features, you can right-click the layers this type of features belong to in Map Content Window, point to Selection and click Pan to Selected Features. Then, the features belonging to the certain type will be

Clear Selection
If you would like to clear selections, there are four methods to do so. First, you can click Selection menu and click Clear Selection. Or you can right-click the map window and click Clear Selection. Also, you can click Clear Selection button on the Tools toolbar to clear the

selections. Method four is to click the blank area on map window. However, if you want to clear part of the selection, please refer to Clear Part of the Selection.

Clear Part of the Selection
If you want to clear part of the selection, please click Selection menu, point to Selection Mode, and click Remove from Current Selection. Then, you can click the selection(s) you would like to clear or drag a rectangle to cancel the selections intersecting the rectangle. If you would like to return to the general way to clear selection, please click Selection menu, point to Selection mode, and cancel the tick before Remove from Current Selection.

Snapping
Snap can facilitate users to precisely connect to an existing feature. For example, when you need to add a new subway route from a subway station, you need to make sure that the route and the station are accurately connected. Snap can help you to complete the task easily.

First of all, you can click the drop-down arrow next to Start Editing on Edit toolbar and then click Snap Setting. Then, Snap Setting window displays. In the window, you can set snap elements and the tolerance. Snapping Tolerance is a specified distance which will be the radius of the mouse cursor when the snapping is set. While the mouse cursor is moving in the map window, snap elements within the radius will be snapped by the mouse cursor automatically. In other words, when you are adding new features and the distance between the mouse cursor and the
5-13

Chapter 5 Editing

existing feature is the snap tolerance, the system will automatically match the feature and the mouse cursor. In Snapping Setting window, you can key in the tolerance and choose the unit as pixels or map units.

Snap elements means the part of the feature you would like to snap; you can choose vertex, edge, midpoint, and endpoint as snap elements. For example, in order to make the new subway route connect to the vertex of the station, users need to tick Vertex of the layer of the station. As a result, when users sketch a line segment and the vertex of the station is within the tolerance, the mouse cursor will be automatically snapped to the vertex. Since an edge is composed of multiple vertices, ticking Edge as the snapping element means that Vertex, Midpoint, and Endpoint are included in the snapping elements; ticking Vertex means Midpoint and Endpoint are included.

Vertex: snapping to vertices of each features of the layer Edge: snapping to edged of each features of the layer Midpoint: snapping to the middle point between two points on a edge Endpoint: snapping to the first point and the last point of a line segment

Snapping can be used with various editing tools to help you add, edit, or even cut features accurately.

Adding Features
Adding Features means to add new features in the existing or blank layers. New features can be points, polylines, or polygons. However, features can be only added into the same geometry layers. Point features can be only added in point layer, and line features can be only added in line layers. The features in polygon layers definitely are polygon features.

In this section, the methods to add features will be introduced by the categories of editing tools. Meanwhile, how to add point, line, polygon multipart features are going to be presented as well.

Before starting editing features, users must enter the editing environment first. Then, click Start Editing, choose the target layer in Edit Target, click Add Features, and choose the editing tools.

Sketch Tool
Sketch Tool can be used to add point, polyline, and polygon features. When you need to add point features, choose the point layer in Edit Target, and click the location you would like to add the point feature in the map window. Then, the point feature is added.

To add a polyline feature, you need to choose the polyline layer you would like to edit in Edit Target. Then, click the map window to create the first vertex, drag a line segment, and click again to create the second vertex. You can repeat the actions until a polyline feature is completed. To finish the sketch, you can double-click or right-click and click Finish Sketch.

Midpoint Tool
Midpoint Tool is used to create a midpoint between two points. If you would like to add a mailbox in the middle of the pavement or add a manhole in the middle of a crossroad, you can apply Midpoint Tool to create the new point feature. Besides, if you would like to add a midline between two street blocks which are also paralyzed with the blocks, you can use Midpoint Tool to create polyline features. Meanwhile, you can use Midpoint Tool to create polygon features. Before using Midpoint Tool to create point features, please enter Start Editing and choose the layer you want to edit in Edit Target. Then, you can select Add New Features and Midpoint, drag a line segment with the Sketch tool , and click. Consequently, the

midpoint of the line segment is created automatically

.

To sketch polyline features with Midpoint Tool, users need to enter Start Editing first, choose the target layer, and select Add New Features and Midpoint Tool. Then, click to create the first point, drag, and click again to create the second point. The midpoint is created between these two points. You can repeat the actions described above; every time a new midpoint is created, it will be automatically connected to the previous point (displayed as a red point). To finish the sketch, you can double-click or right-click to click Finish Sketch.

Nearest Distance Tool
Nearest Distance Tool is to sketch a vertical line connecting a vertex and a specified line segment. This tool can create polyline features and polygon features, but not point features. When you are utilizing Nearest Distance Tool to sketch features, the first vertex is the midpoint of the line segment you create. Then, the next vertex you sketch is the foot of the perpendicular from the last vertex to the line you just drag. Then, you can repeat the actions until the polyline/polygon feature is completed.

When using Nearest Distance Tool to create polyline features, you need to select Start Editing, target layer, and click Add New Features and Nearest Distance Tool. Then, in the Map Window, you can create a new line segment which can create a foot of the perpendicular with the last vertex. As a result, the system will connect the last vertex with the foot of the perpendicular automatically. You can repeat the actions until the polyline feature is finished. To finish the sketch, you can double-click or right-click and click Finish Sketch.

Nearest Distance Tool can be used to create polygon features as well. Firstly, select Start Editing, choose the target layer, and select Add New Features and Nearest Distance Tool. The method to create polygon features is similar to create polyline features. Sketch the first line segment to create the first vertex, and sketch the second line segment. Afterward, the system will create a line segment connecting the last vertex and the foot of the perpendicular of the second line segment. This line segment is the first line of the polygon feature. Then, you can create the third line segment, and the previous vertex (red point) will be connected to the third line segment.

Circle Tool
Circle Tool is used to add polyline features and polygon features. When you are adding a new feature in polyline layers, the new feature composed of a closed line segment is a polyline feature, instead of a polygon feature. No matter a polyline feature or a polygon feature is sketched by Circle Tool, these features are composed of 360 vertices, 1° one vertex.

Before starting to create a circle polyline feature, you need to select Start Editing, choose the target layer, and click Add New Features and Circle Tool. Then, you can click on Map Window to set the center of the circle, drag a circle, and click again to finish the sketch.

You can also add polygon features with Circle Tool. First of all, select Start Editing, choose the target layer, and click Add New Features and Circle Tool. Then, you can click on Map window to set the center of the circle, drag a circle, and click again to finish the sketch.

The methods to add new features described above are to add a single feature. That is to say, one set of attributes indicates a feature. However, in editing features, users may need a set of attributes containing multiple features. Therefore, the methods to create multipoints, multipart features (polylines or polygons) are going to be introduced in the following section.
5-23

Chapter 5 Editing

Adding Multipoint Features
Multipoint feature means multiple points contained in a set of attributes. The method to add multipoint features is to right-click Layers in Map Content Window, and click New Layer in the menu. As New Layer window is open, choose the layer type, click Shapefile-Multipoint, and click Edit in Source Coordinate System. (The method to create a new coordinate system please refer to 4.5).

Copy and Paste Features
In editing features, you can implement Copy and Paste functions. Because the features can be only saved in the layer with the same geometry type, the type of the target layer should be checked. In the following, how to manipulate Copy, Cut, and Paste is going to be introduced.

If you need to copy an existing feature, there are two methods to do so. Firstly, click Start Editing, choose the appropriate target layer, and click Select Features tool. Then, you can select the features you would like to copy, and click Copy button on toolbar. Or you can right-click the

selected feature and click Copy

. Then, you can select Paste

or right-click the map and click Paste

. The new feature will be

pasted on the original feature, so you need to click and drag the new feature to the desired location. As the feature is copied, the attributes are copied to the new features as well.

The second method to copy features is to click the feature you would like to copy, press Ctrl on the keyboard, and drag it to the desired location. Then, the feature is copied and pasted.

Editing Vertices
Each feature on the map is composed of vertices; a point feature is a vertex, a polyline feature contains at least two vertices, and a polygon feature contains three or more than three vertices. If you need to modify the shape of the feature in SuperGIS Desktop 3, you can add and delete vertices and even modify the coordinates of the vertices. In sketching polyline and polygon features, whether the mouse cursor is on a vertex would influence the contents of the right-click menu. That is to say, the position of mouse cursor would affect the possible commands to edit vertices. In this section, what is going to be introduced are the contents of the right-click menu, the methods to add, delete, move the vertices and how to view and modify the coordinates of the vertices.

Introduction to right-click menu
In sketching polyline and polygon features, whether the mouse cursor is on a vertex or not will make the right-click menu different. In other words, the contents of the right-click menu depend on the position of the mouse cursor. Therefore, the commands in the menus will be introduced respectively.

Mouse cursor NOT on a Vertex Stream Mode: After clicking the command, you can hold the mouse left button and drag a line segment with multiple vertices, rather than sketch point features repeatedly.

Move To: You can enter the x, y coordinates in the Move Vertex to X,Y window. Click OK, and the system will create a vertex on the new coordinates. The default value in the window is the coordinates of the last right-click.

5-32

SuperGIS Desktop 3.0

Offset X, Y: According to the X,Y coordinates you enter in the window, the system will create a new vertex on the relative location. The default x,y values are the relative coordinates between the last right-click and the last vertex.

Length: The distance you enter in the window is the fixed distance between the mouse cursor and the last vertex. The last vertex can be seen as the center of the circle, and the Input Distance is the radius. Then, you can create a new vertex on the circumference. The unit of the distance is map unit. The default value of the distance is the length between the last vertex and the last right-click.

Direction: The angle you enter in the window indicates the direction the new vertex can be added. The system will regard the last vertex as the datum point and see the angle you set as the direction to drag the line segment. With the setting, you can only adjust the length, but not the direction. The default angle is the angle between the last vertex and the last right-click.

5-33

Chapter 5 Editing

In the direction setting, the last vertex is the datum point; 0 degree is north to the last vertex. Positive values are clockwise, so 90 degree is east to the last vertex and 180 degree is south to the last vertex. As the angle is set, the mouse can be only moved by the direction of the angle or the supplementary angle. Then, users can modify the length only but cannot change the direction.

Deflection: The last line segment is the datum of the deflection angle which determines the direction you can sketch. Then, you can change the length only. The default value in Input Deflection Angle is the angle between the last right-click and the last line segment.

Length/Direction: In the window, you can enter the length and the angle, and a new vertex will be created based on you setting. The method to set the length and the direction is the same as the methods described above. The default value is the length and the angle between the last vertex and the last right-click.

Parallel: Click to create the first vertex of the polyline feature, and then move the mouse cursor over the line segment the polyline feature needs to paralyze. Then, right-click it and click Parallel. The paralyzed line segment will blink. Afterward, you can sketch a line paralyzing the line

segment.

Perpendicular: The operation of the function is similar to Parallel.

Flip: Click the function, and the direction of the sketch will be reversed. Then you can continue sketch from the first vertex. Thus, this tool can be applied to adjust the direction of the polyline features.

Remove Last Vertex: Click the command, and the last vertex is removed.

Remove Part: Click the command, the part you are sketching is removed.

Remove Sketch: This command is to remove the feature you are sketching. The functions of Remove Part and Remove Sketch are the same as you are sketching a single feature.

5-35

Chapter 5 Editing

Finish Part: Click the function, the current part can be finished. And you can continue to sketch another part of the feature. Sketching with the tool, you can multiple parts belonging to one feature.

Finish Sketch: Click the command to finish sketch.

While you are using the functions on the right-click menu, the status bar on the lower left corner of the window indicates the length and the direction you are sketching.

Mouse cursor on a Vertex Delete Vertex: To delete the vertex.

Offset Vertex: According to the value you enter, the system will offset the vertex. For example, the coordinates of the original vertex are (X1,Y1), and the values you enter are (dx,dy). Then the new coordinates are (X1+ dx, Y1+ dy).

5-36

SuperGIS Desktop 3.0

Move Vertex To: The vertex will be moved to the coordinates you set.

Flip: Click the function, and the direction of the sketch will be reversed. Then you can continue sketch from the first vertex. Thus, this tool can be applied to adjust the direction of the polyline features.

Delete Sketch: This command is to remove the feature you are sketching Finish Part: Click the function, the current part can be finished. And you can continue to sketch another part of the feature. With the tool, you can sketch multiple parts belonging to one feature.

Finish Sketch: Click the command to finish sketch.

Vertex Properties: Click the function, and Edit Vertex window is open. You can see the coordinates of the vertices and modify them directly. Click Finish Sketch to complete the editing.

Chapter 5 Editing

Besides to click the location on the line feature directly, you can also click somewhere outside the line feature, and the system will automatically set the foot of the perpendicular from the location you click to the selected line as the location to split the line. Thus, in this way, what should be noted is that this tool only works when the foot of the perpendicular can be produced form the location you click to the selected line.

If the foot of the perpendicular cannot be produced from the location you click to the selected line, the warning window appears.

Furthermore, Split Tool can be utilized with snapping. Complete the snapping setting first; then, as the mouse cursor is moving within the tolerance distance, the mouse cursor will be snapped to the line feature. Thus, you can split the line feature precisely. No matter how you split a line feature, the attributes of the original feature will be removed as the feature is split, and the attributes of the new features are added. Both of the split tools introduced above can only work when a single line feature is selected. If multiple line features are selected simultaneously, neither Split Tool nor Split can be used.

Divide
Divide tool can be only applied to line features, but the target layer can be the line layer the selected line belongs to or other line layers and point layers. However, the divided line layer will be saved in the target layer. To use Divide tool, firstly click Start Editing, select the target layer, and click Select Features tool. Then, select the line feature in the map window you would like to split and click Divide in Start Editing menu; Divide Line Feature window appears. The system automatically indicates the length of the selected feature, and users need to choose to Divide into parts or Divide by length. Type the value and click OK, and the selected line feature is divided.

Take the line feature for example. The line feature is divided into 3 parts and saved in a line layer.

Take the same line feature for example. The line feature is divided into 3 parts and stored in a point layer, and the divided points are displayed in the point layer.

Chapter 5 Editing

After the line feature is divided, the original line feature is still on the map, and the divided lines are added on the original feature. Therefore, users need to drag the new features to move them. Meanwhile, the attributes of the original feature will not be changed but copied to the attributes of the new features. However, if you choose a point layer as the target layer, the attributes of the new point features are recorded in the attribute table of the point layer but will not copy the attributes of the original line feature.

Buffer
Buffer is an area surrounding a point, polyline, or polygon feature at a specific distance. Therefore, buffered features include points, polylines, and polygons. Buffering is often used for nearby analysis. For example, you can apply Buffer to find a river basin which is near the forester within 100 inches. Users can apply Buffer to point, polyline, and polygon features, which can be stored in either polyline layers or polygon layers. Choosing different target layer to store the buffered features would cause different buffering effects, like the table below: Target Layer Feature Type point ( ) polygon polyline

polygon (



polyline ( )

To create Buffered features, please enter the editing environment, select the target layer, and click Select Features tool. Then, in the map window, select the feature you would like to buffer, and click Buffer in Start Editing menu. Type the distance in Input Distance window and click OK. Then, a new buffered feature is added.

Chapter 5 Editing

As buffered features are created, the attributes of the original feature will not be changed. The new attributes will be stored in the attribute table of the target layer. For example, if you crate a buffered point feature in a polygon layer, the attributes of the point feature will not be changed but the attributes of the new polygon feature will be stored in the polygon layer.

Intersect
Intersect function in Start Editing menu can create a new feature which is the overlapped area of two or more than two features. To use Intersect, firstly click Start Editing, select the target layer, and click Select Features tool. Then, in the map window, select the features whose intersection you would like to create a feature from and click Intersect in Start Editing menu. Thus, a new feature of the common area is created. As the intersection is finished, the attributes of the original features are not changed; the attributes of the new feature will be added in the attribute table, but the contents of the new attributes will not copy the original features.

As the Intersect function is finished, the new feature will cover the original feature. You need to move the feature to the desired location by mouse.

Merge
Merge function is to create a new feature which is composed of two or more than two overlapped features. This function is similar to Intersect, but Merge is not only to combine the selected features but also to combine the attributes of the selected features to be one record. Here is an example:

If you would like to merge these two features, click Merge function and select the feature you want the new feature belong to.

As the selected feature is clicked, the feature will blink. The attributes of the feature you choose will be the base of the attributes of the new feature. The sample here is to select Senior High School.

5-56

SuperGIS Desktop 3.0

After the features are merged, you can indentify the new feature, whose attributes are covered by Senior High School.

Merge function can be used to merge line features as well. Since the line features are involved with direction, the direction of the merged line feature will be the same as the line feature you choose. Here is the example:

The endpoints of the two line features are connected. One is rightward line feature, and the other is leftward line feature.

If you want to merge the two line features, please choose the feature whose direction will be the direction of the new feature. The example here is to choose the rightward line feature.

5-57

Chapter 5 Editing

The endpoint of the merged line feature is moved to the right end, so the line feature is a rightward line.

To merge line features, you need to take direction into consideration because the direction of the road makes the road one way road or two way road.

Separate Parts
Separate Parts tool polygons. can be used to separate multipart features composed of polylines or

If you would like to implement this function, please click Start Editing and select the target layer. Then, select the multipart features on the map and click Separate Parts tool. The multipart feature is separated. Afterwards, when you are selecting features, you can select the features individually. Take the map for example:

Firstly, click Start Editing, select the target layer, and click Select Features tool. Then, select the polygon feature you want to clip and click Clip in Start Editing menu. Clip window appears. You can type in the buffer value and choose to discard the area that intersects or preserve the area that intersects. Take the features for example: If you would like to clip the two intersecting features, click Clip and type 0 for Buffer. Then click Discard the area that intersects and click OK.

The new feature will be like this, and the intersecting area will be removed.

5-61

Chapter 5 Editing

Also, you can type 0 for Buffer and choose Preserve the area that intersects as the option.

The new feature will be like this; the area not intersecting will be removed, and the intersecting area will be left.

Extend/ Trim Features
This tool can be applied to adjust the length of a polyline feature which might be shorter or longer than the length you need. For example, if a road feature on the map overlaps the river, you can apply Extend/ Trim Features tool to modify the polyline feature.

Extend Features To extend a feature, click Start Editing, click Select Features tool, and select the feature you would like to modify. Then, click Extend/Trim Features tool and select the editing tool you need. Sketch a line beside the selected polyline feature, and the polyline feature will be extended. With Extend/Trim Features tool, the selected polyline feature can be extended straightly only, so you need to sketch a line where the selected line can be extended to in order to extend a polyline feature successfully. As the line is sketched, you can double-click or right click to finish sketch.

With Sketch Tool

Trim Features If the polyline feature is longer, you can use Extend/Trim Features tool to trim the line. Firstly, click Start Editing, click Select Features tool, and select the line feature you would like to trim. Then, click Extend/Trim Features tool and select an editing tool. On the map, sketch a line, which

Chapter 5 Editing

should intersect the selected line. Then, you can double click or right click to finish the sketch. Consequently, the system will trim the line segment which is on the right side of the sketch and display the results on the map window. With Sketch Tool

If you use Sketch tool to sketch several vertices continuously, a multipart feature can be produced. The principle of trimming feature is to trim the line segment which is on the right side of each vertex of the sketch.

This function can be not only used with Sketch tool but also Midpoint tool, Nearest-Distance tool, Rectangle tool, and Circle Tool. With Rectangle tool, and Circle Tool, the first intersection will be the end of the extension; to trim the feature, the area covered by rectangle or circle will be trimmed. Extend/Trim Features tool can modify the length of the polyline feature but not the attributes. Thus, the attributes of the polyline feature are not changed.

Mirror Features
This function can be used to add the mirror feature which is exactly on the opposite side of the selected feature, such as the street light and buildings on the street. You can create a new feature and then use Mirror Features tool to create the other feature on the opposite side. To create the mirror feature, firstly click Start Editing and Select Features tool. Then, select the feature on the map you would like to create the mirror feature from and click the dropdown menu to click Mirror Features. Select Sketch Tool, Midpoint Tool, or Nearest Distance Tool to sketch a line next to the selected feature and double click. Then, this sketch will be like a mirror, and the new feature will be created on the opposite side of the selected feature.

The attributes of the new features created by Mirror Features tool copy the attributes of the original feature; the attributes of the original feature remain the same.

SuperGIS Desktop 3.0

How to use “Match whole word only” and “Match case” is introduced in the following: If you tick “Match whole word only”, the system can only find the text that is exactly the same as the text you type. The case of the letters does not affect the search.

If “Match case” is ticked, the system can find the text containing the text you type but might not be exactly the same.

5-79

Chapter 5 Editing

Therefore, if “Match whole word only” and “Match case” are both ticked, the system can only find the text that is exactly the same as the text you type, including spelling and case.

In Find and Replace window, users can upward or downward search the data matching the constraints from the current focus cell. If you have not clicked any cell, the system regards the first cell or the first cell of the first field as the focus cell. When the system has found the last data matching the constraints on the top or the bottom of the field, you click Find Next and the warning window “Search has completed” will appear.

8.2 Setting Map Properties
Many properties are included in Map View, when switching to Layout View the properties you want to display can be set by checking them on Graphics Properties dialog box. The unchecked items will not be displayed on the Layout View but still existed in Map View. Two ways to open the Graphics Properties dialog box, right-click the map and select Properties or right-click on the empty location outside the map, and click Insert →Map Frame.

In the Graphics Properties dialog box Map and Position can be set. The map properties contain Set Visible Items, Frame Style, Visible Layers, Use Extent, Show Grid Lines and Background. In Choose Visible Items set the items you want to output, however, Layer is a must-choose item, it cannot be deleted. You can choose the style and color of frame in Frame Style. In Visible Layer give a check to the layer that you want to output to the map. Use Extent can select the layer extent to display in the frame. Besides in Show Grid Lines can decide whether to show the grid lines and choose the background style. The background settings are for layout view only, which has no influence on background of the map window.

8-6

SuperGIS Desktop 3.0

In the Position tab of the Graphics Properties dialog box, the position and size of frame can be set. The XY coordinates take the lower left corner of the frame as the origin that users can directly enter the value to change the position; also users can directly input values to width and height to change the frame size. If Maintain Ratio is checked, when either width or height is changed, the entire frame size will be changed automatically with the original ratio.

Choosing Output Items
Users can set the output items according to needs. Firstly, open the Graphics Properties dialog box of Layout View, in Choose Visible Items at the upper left corner of the dialog box some items are provided for your options, including Layer, Chart, Label, Feature Selection and Graphics. Among them Layer is a must-choose item, you cannot delete it. The unchecked items will still display in the map window but will not show in the Layout View.

8-7

Chapter 8 Layout and Printing Maps

Setting Visible Layers and Specifying Extent
At the upper right corner of the Graphics Properties dialog box, Visible Layer has listed out all of the layers in Table of Contents, you can check the layer you want to output; at the lower right corner, Use Extent has listed out all of the layers in Table of Contents and Current Extent that you can specify the frame extent the checked layer; if Current Extent is checked, the current extent will be the layer extent. If any item of Use Extent is selected, the map extent is fixed and no more zooming in or out can function.

Setting Frame Style
The frame is designed to add a frame circling the map or grid lines when display the Layout View, which is different from the frame that circles the entire map. Users can decide whether to set frame based on the needs. To set the frame, open Graphics Properties dialog box first, in Frame Style choose a suitable frame type, and set color of the frame on color dropdown menu.

Setting Map Grid
With the map grid, users can label the map coordinates on the Layout View according to X and Y axis in different areas. Firstly, open the Graphics Properties dialog box, check Show Grid Lines and click OK to show the grid lines in the Layout View.

8-9

Chapter 8 Layout and Printing Maps

To set advanced grid line properties, click Grid Settings in Graphics Properties dialog box. Firstly, choose the type for grids, Latitude/Longitude or Measured Grid. If you choose the former, you can set degree, minute, second for longitude and latitude respectively. If you choose the latter, you can set the size for the grid. Furthermore, if the coordinate system of your map is projected coordinate system, you can still use Latitude/Longitude. The system can transfer the coordinate system to the geographic coordinate system. What should be noted is that if the map is not defined with coordinate system, you cannot use Latitude/Longitude. Moreover, you can click Style button to set the color, style of the grid line. In addition, the label of coordinates can choose Show text labels only or Show text tables and grid lines. The former shows the text labels of coordinates only without the grid lines, while the later shows both the text labels of coordinates and the grid lines. Moreover, you can choose whether to use All Borders and Corners. The figure below is the result of selecting Show coordinates at corners.

In the Graphics Properties dialog box you can also set whether to Show Major Tick and Show Minor Tick. Tick Count refers to the number of tick contained in a box. Let’s take the three figures below for illustration, the figure in the left is the result of not checking Show Major Tick and Show Minor Tick, so it shows text labels and unit only. The figure in the middle is the result of checking Show Major Tick only so the text labels, unit and major tick are displayed. The figure in the right is the result of checking both Show Major Tick and Show Minor Tick and Tick Count is 2 so it displays text labels, unit and major ticks, besides, between the major ticks two ticks are placed to represent the minor ticks.

8-10

SuperGIS Desktop 3.0

Due to the text labels of map grid is displayed on the top and left side of the map by default, if you also want to label on the right side and bottom, click Show Both at the bottom in the Grid Line Properties dialog box and the grid line labels display as below.

Click the Font button at the lower right corner in Grid Line Properties dialog box to show the Font dialog box. Here you can set the style, size and color.

Maintaining Ratio
Besides the map you want to output can be resized, the frame of output map can also be resized. See the figures below; figure in lower left side is with original map ratio, while the figure in lower right is the frame with adjusted ratio. Due to the Maintain Ratio in the Graphics Properties dialog box is not checked, the frame size can be adjusted without restrictions. However if you want to fix the frame ratio, please click Maintain Ratio in the Position tab of the Graphics Properties dialog box.

8-11

Chapter 8 Layout and Printing Maps

The figure in lower right is the frame result with Maintain Ratio checked.

Multiple Frames
In the Layout View multiple frames with different extents can be placed together for display. For example, one frame displays the full extent of the map and the other frame displays partial of the extent. Take the figures below for example, if you want to add a frame to the map in lower left, select the frame with Select Graphics tool, right-click to show menu and select Copy. Then paste the frame to the layout by pressing Ctrl+V of keyboard, see the figure in lower right.

8-12

SuperGIS Desktop 3.0

After the frame is pasted, adjust the display extent in the frame. However when the extent of one of the frames is zoomed or adjusted, the extent of the other will be influenced, too. Therefore, it is better to adjust the extent of one of the frames first, then open the Graphics Properties dialog box and check Current Extent in Use Extent to fix the map extent of the frame so that the map extent will no longer change while the other frame extent changes. In the next, you can adjust the map extent of the other frame. In other words, you need to uncheck Current Extent in Use Extent of Graphics Properties dialog box for the frame you need to adjust extent; as to the frame that you do not need to change extent should check Current Extent. The adjusted map should be displayed as the figure in lower right side.

Measurement
While doing with paper-based maps, we used pens and rulers to measure the area or length and even use the planimeter to measure the map. However, working with digital maps now, we can apply the measurement tools provided by SuperGIS Desktop to measure the length, area, etc on the map. There are 3 kinds of measurement tools, including Line Measurement , Area

Measurement

, and Feature Measurement

. The first two tools can be used with mouse to

drag the distance or area to measure. The third tool, Feature Measurement can measure the feature’s perimeter, area, etc. When using the measurement tool, the measurement window will appear and display the measurement results in the window.

Line Measurement
The window below is the result measured by Line Measurement tool. After clicking Line Measurement tool, click the location where you want to start to measure. Then, you can click to add a vertex to along a curve line. Double-click the location where you want to end measuring. In the process of measurement, the measure window will display the measurement results simultaneously. Segment means the length between the last vertex and the mouse current position. Length refers to the total length between the start point and the mouse current position.

If you need to measure several segments and calculate the sum of the lengths, you can click on Measure window. Then, apply the methods mentioned above to Show Sum button measure the first segment and then the second segment. Meanwhile, the sum length shows the sum of the length of the first and second segments, and so on.
9-6

SuperGIS Desktop 3.0

In Measure window, Change Unit function provides numerous metric, British units, and decimal degrees for distance units and area units (decimal degrees can be applied to measure distance only). Users are allowed to choose the unit they need to measure. Since the measure result is recorded as the map unit, Change Unit function only changes the display of measure result rather than the unit of the map itself. Furthermore, if Snap to Feature function is clicked, the snapping function is activated according to the Snap Settings in Start Editing dropdown list. During measuring, as long as the mouse cursor is within the tolerance area, the mouse cursor will be snapped to the feature automatically to improve the accuracy of measurement. The Clear Results is able to clear all the measure results in the current window.

Area Measurement
Using Measuring Area tool , users can drag a polygon to measure the area. The way to

measure is to click Area Measurement and click the position where you want to start to measure the polygon and click again to add another vertex of the polygon, and repeat the actions to finish the polygon. You can double-click to finish the area settings. During the process of measuring, the measure results will be displayed in Measure window, including the segment (the distance

between the last vertex and the mouse cursor), perimeter, and area. Moreover, the other functions in the window, like Sum, are the same as the methods of Line Measurement. Please refer to the description of Line Measurement.

Feature Measurement
After clicking Feature Measurement tool , you can measure the point, line, polygon features

respectively. For point features, the coordinates of the point features will be displayed in the Measure window as the point feature is clicked by Feature Measurement tool. However, the Sum function is useless foe point features.

As a line feature is clicked by Feature Measurement, the length of the line feature will be displayed in the Measure window. If you click Sum, the sum length will be displayed in the window as you click another line feature.

9.2 Querying Features
The previous section mainly presents the way to view the features by zoom in/out tools or panning. However, in this section, the methods to query features and attributes will be introduced. SuperGIS Desktop enables users to query features by clicking, query the related website or document by hyperlinks, and find the features matching the conditions with Find Features tool. As a result, users can utilize the tools to query the attributes of the features on the map.

Querying by Clicking
In viewing the map, users can view the related attributes of the features by Identify tool .

Firstly, click Identify tool and click the feature you want to query. The Identify window appears and shows the attributes of the features. Besides vector data, Identify Tool can also be used to query Raster data.

9-10

SuperGIS Desktop 3.0

Identify Window
The Identify window consists of four parts: “Layers for identifying”, “Layers located in the identifying area”, “Coordinates”, and “Attributes of the identified feature.” In addition, the lower-left corner of the window displays the count of identified features. In “Layers for identifying”, the default result is the attributes of the position of all the layers. You can assign the layers to display in identify results. The options include Visible Layer, Top-most Layer, All Layers, and Active Layer.

Visible layers means that the result presents the attributes of all visible layers of that location. In the table of contents, if a layer is unchecked, attributes of the hidden layer will not be shown in the Identify window. Top-most layer means that the result only displays the attributes of the topmost layer. All layers means that the results are the attributes of all layers of that location. Even the attributes of the hidden layer will still be shown in the Identify window. Active layers are those layers selected in the table of contents. You can select one layer by clicking in the table of contents, or select more than one by pressing the Shift or Ctrl key. Therefore, if you choose Active layers, the Identify window displays the attributes of selected layers. Layers located in the identifying area are the layers based on the layer option. The layers are displayed as a tree view; + and – before each layer name mean to expand or close the tree view. Coordinates mean the location you are identifying in the Map Window. If you click another feature, the coordinates will be modified as well. Attributes of the identified feature show the attributes of the layer; the default is the attributes of the top-most layer. If you need to display the attributes of other layers, you can click the layer you need in the left panel of the window. Identify Count means the count of identified data. For vector layers, it is the count of features,
9-11

Chapter 9 Querying Maps

for raster layers, it is the count of pixels. If you change Layers for identifying, the data in the window do not change immediately but will modify in the next time you query.

Querying Vector Data
Click Identify tool and click the feature you would like to query in the map window, and the

Identify window appears. The left panel shows the identified features and their layers. The attributes in the right panel will be changed as you click different features in the left panel. Furthermore, if you have identified a feature, you can press Shift key to click another feature to identity. The attributes of the second clicked feature will be added to the original identify window, and so on.

Right-click the data in the left panel of Identify window, and you can 在 choose the navigation functions in the menu. Right-click the data in the right panel of Identify window, and you can choose to copy, remove field, reset fields, and reset fields. If you remove a field, the field is removed in the window only, and the original file will not be affected. Moreover, you can click Field and Value to sort the data in ascending or descending order. ‘

Querying by Hyperlinks
To query the features with hyperlink tool, you can create the hyperlinks of websites or documents to the features. As a result, while querying the attributes of the feature and its spatial data, you can use the hyperlinks and related data to have more analysis. In the map window, the features with hyperlinks will be framed with blue lines. First, click Hyperlink tool on Tools toolbar and click the feature framed with blue line. Then, Hyperlink

window shows up, select the target you want to link to and click Link. The hyperlink is launched.

If the clicked feature only has one hyperlink target the hyperlink window will not show up. The hyperlink target will be launched directly after the feature is clicked.

9.3 Selecting Features
While viewing the map, we may not need all of the features on the map but some of them. Therefore, SuperGIS Desktop provides several feature selection tools to view and select features. The feature selection tools include Select Features tool on Tools toolbar, several

Selection ways in Selection menu, such as select by attribute, select by feature, and select by graphic. Moreover, Selection Mode and Options in the menu also assist users in setting selection mode. Additionally, we also can use Find Feature tool to select the results by right-clicking. The mask on Tools toolbar can mask the some features you do not need in the map window to help you recognize and select the needed ones. These functions will be presented in this section respectively.

Chapter 9 Querying Maps

The ways to select features can be set in Selection Mode and Options in Selection menu. The two settings can be used together; after the settings are finished, the selection in the map window will be implemented according to the settings. There are four types of Selection Mode, including New Selection, Append Selection, Remove form Current Selection, and Select from Current Selection. And there are three ways to select, such as “Select features partially or completely within the rectangle”, “Select features completely within the rectangle”, and “Select features that the rectangle is completely within.” In the following, Selection Mode and Selection method are going to be introduced respectively.

Selection Mode Click Selection menu and choose Selection Mode.

Mode New Selection

Definition Click or drag to select features and to make a new selection; the previous selection will be cleared. The features selected by clicking or dragging will be appended to the previously selected features. Drag an area and clear the selections within it. If there is no selected feature, all the features will not be affected. Drag an area to select the features which has been selcted within the area. Only the previously selected features in the area will be selected, but the others will not.

Chapter 9 Querying Maps

Selection Options

Selection Options window contain three parts: 1. Set Selectable Layers: all layers in the map will be displayed in the panel. A check before the layer name means the layer can be selected; otherwise, you cannot select features on that layer. You can press Select All or Clear All button to set selectable layers, and also you can check or cancel layer by layer. 2. Selection Mode: there are three options including Select features partially or completely within the rectangle, Select features completely within the rectangle, and Select features that the rectangle is completely within. These options can be cooperated with Selection Mode in the Selection menu. 3. Tolerance: This number indicates the distance within which features are selected when you use selection tools. The smaller the number is, the more precise the selection would be. The default is 3 pixels and you can type a number as your tolerance.

Since the selections cooperated with different selection methods will results in different selection results, the following section is going to introduce the selections resulted from New Selection, Append Selection, Select from Current Selection which are cooperated with Selection modes.

Selecting by Features
Select by Features in Selection menu enables users to select features through the spatial relationship between features. To Open Select by Features window, click Selection > Select by Features.

Select by Features window contains: 1. Selection Mode includes four options: New selection, Append selection, Remove from current selection, and Select from current selection. 2. Select Layers: To select the target layer(s) which are going to be selected. All layers will be presented in the dropdown list. Notice that not all layers can be selected; thus the dropdown list displays the selectable layers only if you check “Only list selectable layers.” 3. That represents how the target layer and the source layer work together to select features. Options include Intersect, are completely within, completely contain, are identical to, share a line segment with, are contained by, and contain. 4. the features in: refers to the source layer worked with the target layer. In the dropdown list, choose the layer you would like to work with.
9-29

Chapter 9 Querying Maps

Intersect: the features of the target layer intersecting with the source layer will be selected. For example: the point features intersecting the polygon features are selected.

are completely within: The features are completely within the features of source layer will be selected. In other words, only the features of target layer not intersecting the features of the source layer are selected. For example: the roads in a school. Only the roads are completely within the school will be selected.

completely contain: the features of target layer completely containing the features of source layer will be selected. For example: the polygon feature completely containing the line feature, like the left feature, will be selected. However, the line feature intersecting the polygon feature, like the right one, will not be selected.

9-30

SuperGIS Desktop 3.0

are identical to: the features of the target layer are identical to the features of the source layer ill be selected. It means the features should be the same shape and size, but the drawing direction can be different. For example, the two polygon features belong to different layers, but their geometries are the same. Thus, the feature is selected.

share a line segment with: the feature of the target layer sharing a line segment with the feature of source layer will be selected. “Share a line segment” means there must be two points of a line segment overlapped at lease. For instance, the feature sharing a line segment with the source layer is selected, like the map below.

9-31

Chapter 9 Querying Maps

are contained by: The features of the target layer are contained by the features of source layer are selected. Different from “completely contain”, the features intersecting the boundary of the feature of the source layer can be selected. For example: if you would like to select the line features contained by polygon features, the line features intersecting and being contained by the polygon are both selected.

contain: The features of target layer containing the features of source layer will be selected. Different from “completely contain”, the features intersecting the feature of source layer will be selected as well. In the following map, the left feature does not contain the feature of source layer so that it is not selected. The right feature contains and intersects the features but still can be selected.

5.

Use selected features: When you have selected some features in the map window and only need to operate some of the selected features, please tick the item. Take the map for example. If you have selected some features in the map window and want to choose the point features contained completely by polygon features, you can tick the item.

9-32

SuperGIS Desktop 3.0

In the map window, the previously selected line features and polygon features remain selected, and only the point features within the polygon features are selected.

6.

Use buffer to the features: buffer means that the selection can be inexact and be accepted in the tolerance. Thus, you should type a number for the distance as you check the item.

In addition to creating digital map, GIS also facilitates users to apply the analysis tools to calculate, do statistics, and process with the digital map. Then, users are able to handle and analyze the geographic data to make the best policy. SuperGIS Desktop 3 provides Chart, Add XY Data, Grid Maker, Geoprocessing Tools, Buffer, etc. Chart is introduced in Creating Charts; the other tools are introduced in this chapter. First section “Adding XY data” is to introduce how to add the data from the database to SuperGIS Desktop 3 to easily create a point layer with X,Y coordinates. Section 2 explains the meaning of buffering and the method to use Buffer. Section 3 shows how to apply Geoprocessing Tools, such as dissolve, merge, clip, union, etc. Spatial Join will be introduced in Section 4, explaining how to utilize the spatial relationship between layers to combine the attributes. The last section, Grid Maker, shows how to create a grid layer with the tool.

Chapter 10 Analysis Tools

10.1 Adding XY Data
XY data refer to the coordinate data of the map. The function, adding XY data, can help us to export the data to the map and also create a point layer on the map. SuperGIS Desktop 3 not only supports DBF file but also Delimited Text format file (*.txt) and CSV format file (*.csv). The system will also recognize which fields are numeric fields. You can click Tools menu on the top menu bar and click Add XY Data. Then, Add XY Data window is open.

If you do not have any coordinate data, it would be difficult to understand the function. Therefore, we will introduce how to create XY data first and explain how to add XY data to create a point layer.

10-2

SuperGIS Desktop 3.0

Creating XY data
Creating XY data is to create a DBF file or an Excel file with the coordinates of the point features you would like to add. Then, you can directly import the file to SuperGIS Desktop to add point features. Here, take excel for example. Firstly, you can click Full Extent tool on the Tools

toolbar to display the whole map and to make sure the complete coordinate range of the map. While the mouse cursor is moving around the map, the lower-right corner of the window will show the coordinates of the mouse cursor current position.

10-3

Chapter 10 Analysis Tools

After making sure the coordinates of the point features you want to add, you can open Excel file and type X coordinate in column A and type Y coordinate in column B. Then, type 3 sets of coordinates, which are (229579 , 2441350), (220463 , 2435581), and (225586 , 2432354).

After typing the coordinates, please click save

and specify the path to save

in the file. Then, name the file (the sample is “import”). Click save to complete saving.

10-4

SuperGIS Desktop 3.0

Adding XY data
You can add the coordinate data of point features to SuperGIS Desktop to add point features. Click Add XY Data in Tools menu on the top menu bar to open Add XY Data window. Then, click to open the file which records XY data (for example, the Excel file, “import” created in the previous section). Then, click Open.

In Add XY Data window, you need to specify the tab of the excel file you store the data and the columns of XY coordinates. Then, click OK, and Save as window appears. Choose the position to save the file and name the file as Point. Click OK to complete the setting. As for the contents of the dropdown menus of X Field and Y Field, the system can automatically recognize the text title. In this sample, the system can recognize the titles, “X coordinate” and “Y coordinate” in the file. If you do not type any title, the system will use F1 to represent Field1 and F2 to represent Field 2.

10-5

Chapter 10 Analysis Tools

The map window will display the point features which are recorded in the Excel file; the map content window will display the “Point” point layer as the top layer.

SuperGIS Desktop can automatically recognize which fields are numeric. Thus, as you are choosing the field for XY coordinates, the dropdown menu will show the names of numeric fields only for users to choose. When the data are added to the map, the color of the features displayed in the map window and the map contents window are selected randomly. You can modify the color and symbol of the features in Symbology tab in Properties window.

SuperGIS Desktop 3.0

10.2 Buffering
Buffer refers to a zone surrounding the feature on the map at a specified distance. Buffer is useful for analyzing the adjacency. When we would like to know the adjacency between Feature A and Feature B, besides the measurement tool, we can use Buffer to know whether the two features would connect within a particular distance. Buffer can be also applied to indicate the area around the river bank which should not be developed so that the damage caused by flood can be prevented. Consequently, users can perform buffer on point, line, polygon features to create buffer zone for analysis and planning. To open Buffer window, please click the Tools menu and click Buffer.

Users can choose the layer they need from the Input Layer dropdown menu on the top of the Buffer window. Additionally, if you have selected some features, you can decide whether to tick Use Selected Features to perform buffer on the selected features only. If there is no selected on the input layer, Use Selected Features is unavailable. To set Distance, you can choose Value or Field. If you choose Value, please type in the distance you need. The Field dropdown menu lists all of the numeric fields of the input layer; as the field you need is chosen, each feature will be
10-7

Chapter 10 Analysis Tools

buffered at the distance, the value in its corresponding attribute record. On the right side of Distance, you can set the types of buffering, such as Normal, Outer, and Inner. For point layers and polyline layers, you can only choose Normal for the buffering type. For polygon layers, you can choose Normal, Outer, or Inner types. Moreover, the default path for saving Output Layer is the same as the input layer. So, you also can click to browse the new path for saving the

output layer. Besides, if you tick Dissolve Output, the system will dissolve all of the buffer features as a record; if Dissolve Output is not ticked, each feature will be buffered independently.

Buffering
Point features
Take the point layer “meal” for example. You can perform buffer on the selected features or all features of the layer. For the specific features, please select the features you need on the map first. Then, open Buffer window and choose the needed layer in Input Layer. Since this sample is to buffer the selected point features, please tick Use Selected Features. Then, you can choose Value or Field. Here, we choose Value and type 50 for the distance. After confirming the path for saving Output Layer, you cam choose whether to tick Dissolve. Here, we do not tick Dissolve Output, so the attribute data of the new layer will be corresponding attributes of the input layer.

10-8

SuperGIS Desktop 3.0

The new buffer layer will be added to the map window and placed as the top layer. Like the figure below, since Dissolve Output is not ticked in buffering, the attribute table includes 3 records.

If Dissolve Output is ticked in buffering, the attribute table of the new layer will dissolve all of the buffered features as a record.

10-9

Chapter 10 Analysis Tools

Polyline features
Take the polyline layer, “road”, for example. Open Buffer window, select “road” for Input Layer. Since we do not select any features on the map, Use Selected Features function is unavailable. Then, to set the distance, you can choose Value or Field. Here, we choose Value and type 10 for the distance. Due to polyline layer, we can only choose Normal type for buffering. After confirming the path for saving Output Layer, you can choose whether to tick Dissolve Output. This sample does not tick Dissolve Output. The figure below is the line features before being buffered.

The buffered line features are displayed below. Because Dissolve Output is not ticked in buffering, the attribute data of the new layer will be the corresponding data of the input layer.

10-10

SuperGIS Desktop 3.0

Polygon features
This sample is the polygon layer, “school”. We take a polygon feature for example. So, please select a polygon feature on the map first. Then, open Buffer window. Choose “school” in the Input Layer dropdown menu and tick Use Selected Features. To set Distance, you can choose Value or Field. Here, we choose Value and type 10 for the distance. Since the feature is polygon, we can choose Normal, Outer, or Inner for the type of buffering. After confirming the path for saving the output layer, you can choose whether to tick Dissolve Output. Here, we do not tick Dissolve Output.

The four figures below are the features before being buffered, buffered with Normal type, with Outer type, and with Inner type. Normal type is to create a new feature from the original feature at a specified distance. Therefore, the new feature covers the original feature (The dotted line is the area of the original feature; the dotted line will not show in manipulation). Outer type is to create an outward polygon feature from the boundary of the original feature at the specified distance, so it does not include the original feature. Inner type is to create an inward feature from the boundary of the original feature at a specified distance. Original Normal Outer Inner

10.3 Geoprocessing Tools
Spatial data in GIS are displayed in points, polylines, and polygons. Generally speaking, different types of features are saved in different layers. However, if we would like to intersect Layer A and Layer B or clip a polyline layer on the other layer, we can apply the geoprocessing tools to deal with the spatial data. As a result, these tools can help users to satisfy the demands for spatial data and also facilitate the statistics and analysis of spatial data.

In SuperGIS Desktop, the geoprocessing tools are all in Geoprocessing Tool window. There are 5 operations, like dissolve, merge, clip. Intersect, and union. The functions of the 5 tools are introduced in the following table. Operation Illustration Definition Dissolve aggregates features that have the same value for an attributes.

Dissolve

Merge

Merge appends the features of two layers into a single layer.

Clip

Clip uses a clip layer on your input layer. The attributes are not altered. Intersect cuts an input layer with the features from

Intersect

an overlay layer to produce an output layer with features that have attribute data from both. Union combines features of an input layer with

Union

polygons of an overlay layer to produce an output layer that contains the attributes and full extent of both layers.

10-12

SuperGIS Desktop 3.0

In this chapter, the manipulation of each operation will be introduced. To open Geoprocessing Tool window, please click Geoprocessing Tool in Tools menu.

Geoprocessing Tool window can be divided into 5 blocks: A. Operation: 5 different computations and the definitions are listed. B. Input Layer: the layer you would like to process with. You can choose whether to tick Use Selected Features and specify the field. Then, you can proceed with field statistics and also display the results in the attribute table of the output layer. C. Operation Layer: the target layer. Users can choose whether to tick Use Selected Features to aggregate the selected features only. D. Output Layer: you can set the path for saving and the name of the output layer file. The default path for saving is the folder of the input layer. The default file name is “the name of input layer_operation", such as geology_Dissolve. E. Progress Bar: the geopressing progress is displayed here. When you process quantities of data, please be patient to wait for the results.
10-13

Chapter 10 Analysis Tools

Dissolve
“Dissolve” creates a new layer by merging adjacent polygons that have the same attributes and removes the boundaries of the polygons. In SuperGIS Desktop, it is the only operation which can be performed on one layer. The others all involve two-layer operations. Take Northeast Coast layer for example. If you would like to dissolve the EDESC field in geology, please open Gepprocessing Tool window and choose Dissolve. Then, choose geology for the input layer and choose EDESC for Field. As the path for saving output layer is confirmed, please click OK. As the features are dissolved, the message window “Do you want to add this layer to your map?” will show. Click Yes, and the layer will be added as the top layer.

10-14

SuperGIS Desktop 3.0

Figure 1 shows the features before being dissolved and their attribute table; Figure 2 displays the dissolved features and their attribute table.

Figure 1

Figure 2

Since the field for dissolve is geologic data field, the features with the same geologic data are dissolved as one feature. Therefore, some of the boundaries of the features are altered.

10-15

Chapter 10 Analysis Tools

Dissolve the selected features
The method described above is to dissolve all the features of a layer. Besides, you can only dissolve some selected features. Thus, when you have selected some features on the layer, Use Selected Features will be available in Geoprocessing Tool window. You can choose whether to tick this function. If you tick it, the system will only dissolve the selected features. If not, the system will dissolve all of the features on the layer. Take the layer “geology” for example. You can select the needed features with Select Features tool, and the selected features will be displayed with the selection symbol. Then, open Geoprocessing Tool window, click Dissolve, select “geology" for Input Layer, and tick Use Selected Features. Also, choose EDESC for Field. As the path for saving Output Layer, click OK and add the new layer to the current map.

The new layer will be displayed like:

10-16

SuperGIS Desktop 3.0

Dissolve with field statistics
Besides dissolve operation, SuperGIS Desktop also provides field statistics function for statistics analysis and add the statistics results to the attribute table of the output layer. Here, take the layer “geology" for instance. Firstly, select the features on the map, open the Geoprocessing Tool window, choose Dissolve, and choose “geology" for Input Layer. Then, tick Use Selected Features and click Field Statistics. In Field Statistics window, there are several functions available, and you can choose Count as well. You can choose the field for statistics and the function you need. If you need to show how many records are from the input layer, please tick Count. As all of the settings are completed, click OK. Then, back to Geoprocessing Tool window, choose the field for dissolve and confirm the path for saving the output layer. Click OK to dissolve the features.

10-17

Chapter 10 Analysis Tools

The dissolved layer is displayed in the map window; the attribute table of the new layer records the fields of statistics results. In this sample, we ticked AREA for average and tick Count. So, there are two fields, “A_AREA" and “Count" added. “A_AREA" represents the average area of the input features. “Count" refers to the number of the input features.

10-18

SuperGIS Desktop 3.0

Merge
Merge is to combine two layers into one layer. Also, the attribute data will be combined to one attribute table. Merge operation can only be performed on the features with the same geometric type, such as point and point features, line and line features, polygon and polygon features. Therefore, when you select a layer for input layer, the operation layer dropdown list will show the same type layer only to prevent you from choosing other types of layers which cannot be merged with.

The sample here uses the layers “geology" and “Geology." Add the two layers into the map and open the Geoprocessing Tool window. Then, click Merge and choose “geology" for Input Layer and “Geology" for Operation Layer. As the path for saving the output layer is confirmed, click OK to complete the merge operation.

10-19

Chapter 10 Analysis Tools

The merged layers will be displayed as the top layer in the map window. The attribute table will contain the attribute data of the two layers but based on the attribute table of the input layer.

10-20

SuperGIS Desktop 3.0

Merge selected features
Geoprocessing Tool can merge the selected features to create a new layer. The manipulation is similar to merging layers described above. Firstly, select the features on the map, click Merge in Geoprocessing Tool window, and select the layers to merge. Tick Use Selected Features for both Input Layer and Operation Layer. If you tick Use Selected Features for one layer only, the system will merge all the features of the other layer.

As the features are merged, the new layer will be added to the map as the top layer. The attribute table also combines the attribute data of the two layers.

10-21

Chapter 10 Analysis Tools

Merge in Geoprocessing Tool and Merge in Start Editing dropdown menu both can merge features. However, the former is to combine the features to create a new layer; the latter is to merge features and create a new feature.

10-22

SuperGIS Desktop 3.0

Clip
Clip is to clip the features with the polygon layer and to extract the features from the input layer. Therefore, to implement clip operation, the input layer can be any geometric type of layers, but the operation layer must be a polygon layer. Take the layers “river" and “area" for example. If you would like to extract the “river" within the “area" to create a new layer, please open Geoprocessing Tool window, choose Clip for operation, select “river" for Input Layer, and select “area" for Operation Layer. After checking the path for saving Output Layer, click OK.

As the new clip layer is created, it will be displayed on the map as the top layer.

10-23

Chapter 10 Analysis Tools

Clip the selected features on the input layer
Users can only clip the selected features. First of all, select the needed features on the map, open Geoprocessing Tool window. Then, choose Clip for Operation, select “river” for Input Layer, and tick “Use selected features.” Also, select “area” for Operation Layer, confirm the path for saving Output Layer, and click OK.

The new layer is created and displayed as the top layer on the map with the bold lines.

10-24

SuperGIS Desktop 3.0

Intersect
Intersect computes the geometric intersection of two layers and creates a new layer only containing the features in the common area of the two layers. The attribute table of the new layer lists the data of the two layers. What should be noted is that the intersection must be performed on polygon and polygon layers, point and polygon layers, or polyline and polygon layers. The intersection cannot be performed on point and point layers, polyline and polyline layers, and point and polyline layers. In this sample, we take the POI layer and School layer for example. If you would like to intersect POI layer and School layer, please open Geoprocessing Tool window, choose Intersect. Then, select POI for Input Layer, select School for Operation layer. As the path for saving the output layer is confirmed, click OK. The figure below is the map before intersection, and the attribute table of POI layer.

10-25

Chapter 10 Analysis Tools

After intersection, the new point layer will be displayed as the top layer on the map. Like the figures below, the attribute table contains the attributes of the point layer and the polygon features.

10-26

SuperGIS Desktop 3.0

Intersect the selected features
When performing Intersect operation, users can only intersect the selected features. In this sample, we take the layers “river” and “town” for example. If you would like to find the features of the polyline layer “river” within the selected area in the polygon layer “town”, please select the features first. Then, choose Intersect for Operation, select “river” for Input Layer, select “town” for Operation Layer and also tick Use Selected Features. As the path for saving the output layer is confirmed, click OK. The figures below are the selected area for intersection and the attribute table of “river” layer.

10-27

Chapter 10 Analysis Tools

As the intersection is completed, the new created polyline layer will be added as the top layer on the map, like the figure below. The attribute table of the new layer contains the data of the original polyline layer and the polygon layer.

To perform intersection operation with the selected features, the features of Input Layer and Operation Layer can be selected for intersection.

10-28

SuperGIS Desktop 3.0

Union
Union operation is to combine two layers into a new layer, which is the union area of the two layers and contains the data from the tow layers.

10.4 Spatial Join
Spatial Join is a type of spatial analysis, applying the spatial relationship between layers to join the two layers’ attribute data to create a new layer. Therefore, the new layer still contains the features of the original layer, but the attribute data of the new layer will add new fields or be appended with the fields of the other layer. For example, when you would like to find out how many gas stations in a certain district or search the nearest restaurants, you can apply Spatial Join to fulfill the goal. So, you can open Spatial Join window, choose the target layer and the joined layer, and specify the operation. Then, the layers can be joined to create a new layer and a new attribute table. The way to open Spatial Join window is to click Tools menu and click Spatial Join on the menu.

In Spatial Join window, there are Target Layer dropdown menu and Joined Layer dropdown menu. The menus list all of the layers displaying in the current project. You can choose the layer for Target Layer as the spatial join base and choose the layer you would like to join for Joined Layer. If the layer you would like to join is not in the current project, you can click to browse

the layer you need. According to the layer type you choose in the menu, the right side of the window shows different operations. You can choose the most suitable operation to join the layers to meet your needs. Then, you can confirm the path for saving the output layer; the default folder is the folder of the target layer. As all the settings are finished, click OK. Then, the progress bar at the bottom of the window shows the progress of the operation. After the layers are joined, the system will show “Do you want to add this layer to your map?”; if click OK, the new layer will be added to the map. There are different operations for joining different types of layers. The join operations for each type of layer are introduced in the following table.

Target Layer Joined Layer

Point layer
Each feature will be given a count value that shows how many joined features it intersects.

Polyline layer
Each feature will be given a count value that shows how many joined features it intersects. Each feature will be given all the attr butes of the joined feature that is closest to it and a distance field is added. Each feature will be given a count value that shows how many joined features it intersects. Each line will be given all the attributes of the joined line that it is substring of.

Polygon layer
Each feature will be given a count value that shows how many joined features it intersects. Each feature will be given all the attributes of the joined feature that is closest to it and a distance field is added. Each feature will be given a count value that shows how many joined features it intersects. Each feature will be given all the attributes of the joined feature that is closest to it and a distance field is added.

Feature intersection
When you would like to know what intersects a layer, you can apply the operation “Each feature will be given a count value that shows how many joined features it intersects.” in Spatial Join window. For instance, if you would like to know how many restaurants in a certain area, you can utilize a polygon layer covering an area and a point layer recording the data of restaurants to find out how the two layers intersect. Take the layers “meal” and “area” for example. “Meal” layer includes lots of point features; “area” is only composed of a polygon feature. If you want to know how many features of “meal” located in “area”, please open Spatial Join window, choose “area” for Target Layer, and choose “meal” for Joined Layer. Then, choose “Each feature will be given a count value that shows how many joined features it intersects.” After the path for saving the output layer is confirmed, click OK.

10-35

Chapter 10 Analysis Tools

As the operation is finished, the system will show “Do you want to add this layer to your map?” If you click Yes, the new layer will be added to the current project.

The new created layer will be added as the top layer on the map. When you open the attribute table of new layer, you can find that one field, “Count”, is added to the table, and the new field records the how many features of “meal” intersect “area.”

Since the target layer is a polygon layer, the new joined layer is a polygon layer. The spatial join method described above can not only apply to polygon layer and point layer but also other layers.

10-36

SuperGIS Desktop 3.0

Closest features
The operation, “Each feature will be given all the attributes of the joined feature that is closest to it and a distance field is added.”, can help users to find the closest features and create a new layer which contains the corresponding attribute data and the distance to the corresponding features. For example, when you would like to know the distance between each restaurant and its nearest road, you can apply the function. Take the layers, ”POI” and “road” for instance. The features of POI are distributed near different roads. So, you can apply the spatial join operation to find out the distance between each point feature and its closest road.

Firstly, open Spatial Join window, choose “POI” for Target Layer, choose “road” for Joined Layer,
10-37

Chapter 10 Analysis Tools

and choose “Each feature will be given all the attributes of the joined feature that is closest to it and a distance field is added.” (If the point or polyline is completely inside an area, the distance will be regarded as 0.) As the path for saving the output result is confirmed, please click OK.

If the polyline intersects with a polygon, the distance will be seen as 0 as well.

The joined point layer is added to the map, like the figure below. As the attribute table of the layer is open, you will find that the system automatically adds the nearest feature data to the table and also adds a Distance field for recording the distance between the point feature and its nearest line feature.

10-38

SuperGIS Desktop 3.0

Overlapped features
When both of the target layer and joined layer are both polyline layers, one of the operation is “Each line will be given all the attributes of the joined line that it is substring of.” This function can join the attribute data of the overlapped polyline features of the two layers. If you have two polyline layers recording the rivers’ data, and the two layers overlap, you can use the spatial join operation to view the attribute data of overlapped part of the two layers. In this sample, we use the layer “river” in Northeast Coast and the layer “River” in Yilan as the example. Due to the features from different layers, the data are recorded in different attribute tables. Therefore, you can apply the spatial join function to view the attribute data of rivers within Northeast coast, and the data of Yilna are recorded in the same attribute table as well.

10-39

Chapter 10 Analysis Tools

To join the two polyline layers, firstly open Spatial Join window, choose “river” of Northeast coast for Target Layer, and choose “River” of Yilan for Joined Layer. Then, click “Each line will be given all the attributes of the joined line that it is substring of.” As the path for saving the output result is confirmed, click OK.

The new created layer will be added as the top layer on the map. As the attribute table is open, you can find that besides the attribute data of the original layer the attribute data of the joined layer are added, too. The attributes of the overlapped features are displayed in the table; the attributes of the features which are not overlapped are displayed 0 in the field. The overlapped features and their attribute data are displayed with the selection color in the figure below.

10-40

SuperGIS Desktop 3.0

Features completely falling in another layer
The function, “Each feature will be given all the attributes of the joined polygon that it completely falls inside.”, can find out the features of some layer completely falling in another polygon layer and add the corresponding attribute data to the target layer. For example, two polygon layers are overlaid on the map at the same time; one records the data of schools, the other the data of districts. Then, you can apply Spatial Join to join the two layers to create a new layer whose attributes include the records of the target layer and the corresponding data of the joined layer. Here, take the layers, “park” and “town” in Taipei for instance. “Park” records the data of schools and parks; “town” records the data of districts in Taipei. Therefore, Spatial Join can help users to view which features of “park” completely fall in the “town” layer.

10-41

Chapter 10 Analysis Tools

To join the two layers, firstly open Spatial Join window, choose “park” for Target Layer, and choose “town” for Joined Layer. Then, select “Each feature will be given all the attributes of the joined polygon that it completely falls inside.” for Operation. As the path for saving the output result is confirmed, click OK.

The joined layer will be displayed as the top layer on the map. As the attribute table is open, you will find that the attribute data of “park” are preserved and the corresponding attributes of the districts are added to the table, too.

10.5 Grid Maker
Grid refers to the basic geometry units for the storage, display and process of geographical data. To create a grid is like to create a layer. Grid is used to divide the continuous geographical space into discrete units in order to record, store and manipulate data. Grids are also useful in mapping and positioning. To create a grid, firstly click Tools menu → Grid Maker. Then, Grid Maker window is open, and you can choose the extent of the grid to cover “Map extent” or some layer from Extent dropdown menu. If you choose “Custom”, you need to type in the values in the text boxes to define the extent. Moreover, you can choose Count or Size to customize the grids. If you choose Count, the horizontal and vertical numbers can be set separately, and the system will automatically calculate the width and the height of each cell. If you choose Size, you can define the width and height of the grid by yourself. At last, as the path for saving the output is confirmed, click OK.

Then, the system will show “Do you want to add this layer to the map?” window. Click Yes, and the layer will be added to the current map.

10-43

Chapter 10 Analysis Tools

As the grid is added to the map, the grid will be displayed as the top layer so that the other layers will not be displayed. Therefore, you can set the transparency of the grid layer to make the grid and the other layers under the grid display clearly. The color of the grid is chosen by the system randomly, but you can double-click the color block of the grid in map content window to set the color you need.

After the transparency is adjusted, you can clearly view the grid and the other point, polyline, and polygon layers.

10-44

SuperGIS Desktop 3.0

If you need to view or edit the attribute data of the cells, you can open the attribute table to edit. The way to open the attribute table is the same as the way to open other layers’ table. Right-click the name of the grid, and click Open Table.

There are three default columns in the grid attribute table, such as ID, Col_Name, and Row_Name. ID is the serial number of the cells. Col_Name is named after the column, from left to right in alphabetic order, and the first column is A. If there are more than 26 columns, the column will be named with 2 letters, like AA, AB, etc. Row_Name is the number of the rows; the first row is numbered 1. In addition, you can select the records in the attribute table, and the corresponding cell will be displayed with the selection symbol on the map window. Similarly, if you select the cells on the map window, their records will be displayed with selection color. If you choose a layer for the extent of the grid, the result will be like the figure below. The grid only covers the extent of the layer.

Appropriate graphs might be the easiest way to figure out the information. Using graph is another way to present the features on the map so that users may compare and contrast the attribute data o f the features and recognize the changes or trends in the data.

Appendix 4 Graph

With charts, we can easily interpret some information, for example, the comparison and contrast of the numeric data of related features. Thus, users can not only recognize the changes of numbers but also figure out the trend of the development. In this chapter, we should know which type of chart we need first. Therefore, SuperGIS Desktop built-in 5 types of charts are going to be introduced firstly to help you choose the most suitable one to create a chart. Then, we will present how to manipulate and create each type of charts respectively and step by step. Furthermore, the methods to set the appearance of the charts will be displayed so that users can learn how to make their charts more appropriate. At last, how to modify and manage the charts will be presented.

Chart Types
Appropriate graphs might be the easiest way to figure out the information. Using graph is another way to present the features on the map so that users may compare and contrast the attribute data o f the features and recognize the changes or trends in the data. SuperGIS Desktop Graph tool has 5 built-in graph types, including bar, line, area, scatter plot, and pie. Also, you can display the charts in 2D, 3D, or stack. Thus, you can choose the graph chart which fits you the most to display the data in the best way.

Graph Type Bar

Definition
A bar graph is composed of two or more than two bars. Each bar represents a specific attribute value. The graph can be used to compare the values or show the trends. Also, bar chart can be created with other graphs. Bar is suitable for displaying the changes of data within a certain period or comparing the values of different features. Graph tool provides Vertical Bar and Horizontal Bar.

2D

3D

Stack

IV-2

SuperGIS Desktop 3.0

Line

A line graph is composed of one or multiple lines. Line graphs mainly display the trends of values within a continuous scale. This kind of graph can be used with other graphs. Graph Tool provides Vertical Line and Horizontal Line.

Area

An area graph consists of the lines and area which are between the lines and X axis shaded. The lines are like Line graphs to present the trend in value, and the areas show the difference of quantities. Area graph can be used with other graphs. Graph Tool provides Vertical Area and Horizontal Area graphs.

Scatter Plot

Scatter plot graph shows each attribute as a point on the graph. The graph also can display the relationship between the attributes so that you can plot the attributes from more than two fields to create a mixed or overlay graph. Generally, the graph is usually applied to show the data distribution and the comparison of values.

Pie

Pie charts consist of a circle or pie, divided into two or more parts. Pie Charts are used to show the relationship between parts in proportions or ratios. Pie chart can display a certain field in a layer, so it is not suitable for creating mixed or overlay graph.

There is no principle for choosing graph type. It only depends on what kind of information users want to express to readers. Thus, even the same data can be displayed with different meanings in different graphs.

Creating a Graph
Creating a graph depends on how users would like to display the attributes of the layer. Therefore, before creating a graph, users have to understand the data so that they will be able to choose the appropriate graph type to analyze their data. For example, line graphs are suitable for the continuous data related to time; pie charts are suitable for the statistics data of sum or ratio. A good chart can show the trend in values, distribution, and the relationship between data. SuperGIS Desktop Graph can help you to create graph of all of the attributes of a layer or only some specific ones. The steps to create a graph are:

1. Open Create Graph Wizard. 2. In Graph Type, choose the type you would like to create. 3. In Layer, choose the source layer. 4. In Y Field, choose a field of the source layer as Y axis. 5. In X Label Field, choose a field of the source layer as the item on X axis. 6. In Color, choose the color you want the items in graph to be displayed. 7. Set the appended field for the graph type you choose. For example, if you choose Vertical Bar, you can set Multiple Bar Type. 8. Set whether to add a new graph tab to create a mixed or overlay graph. 9. After the graph settings are finished, click Next.

Appendix 4 Graph

Creating Graphs of Selected Features
With Graph, you can graph your current spatial data. SuperGIS Desktop Graph provides two ways to create graphs, Show All Records or Show Only Selected Records. Thus, if users want to graph the selected features, they only need to use the tools to select features or attributes. Consequently, users can create graphs easily.

Use Select Features tool to select features and create graphs In SuperGIS Desktop, one of the methods to select features is to select by Select Features tool. You can drag a rectangle to select the features within an area or some specific features. As the features are selected, you can use the Graph to plot the features.

1. 2. 3.

Click Select Features tool on Tools toolbar. Drag a rectangle on the map to select the features. The selected features are displayed with the selection symbols on the map.

4. 5. 6. 7.

Open Create Graph Wizard. In Graph Type window, complete the settings and click Next. In Appearance window, choose Show Only Selected Records, and click Next. The graph of selected features appears.

Appendix 4 Graph

Creating Mixed Graphs
You can use SuperGIS Desktop Graph to create a mixed graph. Mixed graph allows you to use one type of graphs to display the data of different fields in a graph. Through comparing with the data on the graph, readers can recognize the variances, like the male and female distribution, the exhaust proportion in the air. When you want to create a mixed graph in Create Graph Wizard, you can right-click the graph tab and choose Insert Item. A new graph tab is added. Switch the graph tab, and you can set the properties of the new graph, like the layer, color, etc. To create a mixed graph, you only need to set the graphs as the same type of graphs. For example, both of the graphs are Vertical Line or Horizontal Line. Then, set the properties of the graph tab. A mixed graph is created.

Pie charts are only applied to display the data of a field to present the relationship between one item and the whole data. Thus, pie charts cannot be used to create mixed graphs or overlay graph.
IV-10

SuperGIS Desktop 3.0

Creating Overlay Graphs
You can apply SuperGIS Desktop Graph to create overlay graphs. Overlay graphs refer to create a graph composed of more than two types of graphs. Integrating different numeric data into a graph can display the data clearly. For example, overlay graphs can plot the relationship between the estimated house prices and the real house prices in some city or the population variances in recent year within a district.

When you want to create a mixed graph in Create Graph Wizard, you can right-click the graph tab and choose Insert Item. A new graph tab is added. Switch the graph tab, and you can set the properties of the new graph, like the layer, color, etc. To create a overlay graph, you need to decide the graph type first. For example, the first tab uses Vertical Line, and the second tab uses Vertical Bar. Then, set the properties respectively. A overlay graph is created.

Pie charts are only applied to display the data of a field to present the relationship between one item and the whole data. Thus, pie charts cannot be used to create mixed graphs or overlay graph.
IV-11

Appendix 4 Graph

Setting Graph Tabs
As several graph tabs have been created, you can hold the left key of mouse to drag the tab to change the order of graphs. Each tab is like a individual layer; the order of the tab will influence the display order in the graph. For example, when more than two fields need to be displayed on mixed graph or overlay graph, the tabs close to the right side would be displayed at top, and the tab close to the left side would be displayed at bottom.

Besides Insert Item, users can also use Delete Item. Right-click the tab and choose Delete Item, and the tab is removed. However, if there is only one graph tab, it cannot be removed.

To avoid being confused with the graph tabs, users can name the tabs respectively. Right-click the tab and choose Rename. Users can rename the tab. Or users can double-click the tab, and the text become editable. Then, users can rename the tab.
