Task (3):- P3.2

In this part of the task I'm going to explain some of the
.information on Google Earth and I will explain it
Importance in life, and what are the aspects on which the
surveyor in Google Earth to do the survey, and the
-:importance of this application in Surveying Engineering
Google Earth
-:Definition
It is one of the most common software in the mapping
.program, where the user can view anywhere in
The world by typing the name of this place into the search
bar, where the program will be brought in for a lot of
information about this place, in addition to the geographical
.picture of this place
Is a cartographic and geographic information program in the
store was called originally Viewer 3D Earth that Google has
created the company, a program of the Map of the drawing of
the Earth through the installation of images obtained from
satellite or aerial photography, Or Depending on Geographic
information system GIS, Google Earth was introduced
different images satellite of the Earth’s surface, allowing
users to see things like cities and houses, which is available
to all people and became the users can work on them
.through phones Smart, or computers
-:Google Earth in the Surveying
A lot of surveying operations rely on and GIS with enormous
development scene in the information, especially information
State Grid Technology Internet and appearance of Google
earth program is easy to use and widespread as a means, so
the space management and implementation of plans study
programs available to work multiple applications Google earth
program By studying a large sum of programs has been
reached to identify programs that can be used successfully in
-:the work of some applications, such as
.Map projection photographers on the space program (1

Task (3):- P3.2

.Sign a number of points on the Google earth program (5
Dropping maps on AutoCAD on Google Earth are of great
benefit for those in charge of overseeing the cadastral areas
within cities where come maps AutoCAD program for review
shall be the first step dropped onto the GIS if available, or on
Google Earth and then can review the cross elements from
where the completion of all elements of cadastral or not, and
is identical to the coordinates of the user based systems and
.many applications system
That the use of Google Earth desktop does not sing for (1
.lifting the field surveying work must be surveying equipment
And that Google Earth is not used in evaluating the (2
accuracy of cadastral work, but only in the initial
identification and initial location and the nature of surveying
work done and not to assess the accuracy of this surveying
.works
-:Uses of Google earth
Taken coordinate and elevation point and photo of any plaice
on the world, and adding photo of GIS software to make a
.map
This is because the cadastral work is supposed to be where
the errors in the range of centimeters, while Google Earth if
we are to rely on him and we use an alternative to raising
areal errors will not be less than two meters or meters at
.best
-:Advantages of Google Earth
.Free_1
.Available on a wide array of devices (2
.Up-to-date maps and data (3
.Extremely detailed (4

.3D capabilities (5
.Additional layers available (6
.Ability to "visit" select buildings (7
.Historical view (8
.Can be embedded into web pages (9
.Available in 45 languages (10
Task (3):- P3.2

-:Disadvantages Google Earth
.High bandwidth requirement for best performance (1
.Low resolution in some areas (2
.Requires internet access (3
.Not all areas of globe are covered - some are restricted (4
.Less developed countries are poorly presented on maps (5
Determine the coordinates of is not accurate and be the (6
.error rate of more than 2 meters

how it is used and shows us how to control and watch all the

This video also shows us demonstrate the use of Google
Earth, and explains the advantages of this program and ways
.to take advantage of it
Methods and procedures drop and install these

We through the search bar to find the site you want to (2
.extract coordinates
After finding the desired location we go to the Options bar (3
at the top and choosing a "nail with a yellow" screw this job to
.determine which coordinates
We are now dropping the screw at the desired location in (4
.map of the Google Earth
Task (3):- P3.2

Key steps to extract the coordinates anywhere (X ,Y)
-:of the Google Earth map
I am referring to the point you want to extract coordinates (1
."through the "yellow nail
After selecting Points required coordinates X and Y appear (2
.to us within a rectangle
.We apply this method to all the remaining points (3
.We save these coordinates on the computer (4
Finally from file bottom we go to save and save it as a (5
. picture

extract coordinates cooperation with engineered Haneen

Task (4):- P4.2

Measuring the area by picture taken by Google
earth
-:Procedure
Open GIS software and add picture and pre-defined
coordinate by pressing on layer and then properties then predefined then projected coordinate, choose natural grade
WGIS 1984 web then we press on draw and chose polygon
and then draw the borders of the land that we want to
measure its area , and then double click on polygon, then
properties , then we chose the red frame and copy the area
.from inserting text and paste area that we took it

Measure distances and areas in Google
Earth without picture
Through computer versions of Google Earth you can measure
.the length of the earth with a line or path
-:You can also measure
Oceans using circles (1

Three-dimensional buildings (3
-:Procedure
Open Google Earth (1
.Go to somewhere on the globe (2
In the menu bar, click on Tools> tool to measure (3
.distances, Box will appear
In the lower right side of the tool box measuring (4
.distances
.Click on the tab to measure the things that you want (5
-:In Google Earth, can be measured
.Line:- The distance between two points on the map
.Track:- The distance between multiple points on the ground
On the map, click on the starting point for measurement (6
have
.Click on one of the end points (7
You will see a line or shape on the globe show the thing (8
which you are measured to him. Measurements will appear in
