3. GIS Stands for - Geographic Information
System
G + IS
(Geography) + (Information System)
(Geography) + (Information System)
Geography is the science that Studies the land
feature, inhabitants, and the phenomena of
Earth.
Information system – A way of manipulating the
information digitally (Using computer or digital
Device).

4. Step 1: Open ArcGis

5. Step 2: Click on yellow mark
and then click on add data
Step 2 Continue: A Menu
open like this

6. Step 3: If anybody have Installed a Fresh
ArcGis, Click on Connect to Folder
Con..: Add a folder
wherever data is
saved

7. Step 3 Continue: Data (Map)
show in ArcGis & map can be
load.
Now Data has been
loaded but if showing
“Unknown spatial
reference” it indicates
that data is not
georeferenced.

8. The process of describing the correct location and shape of
features, typically by assigning coordinates from a known
reference, such as latitude/longitude, universal transverse
Mercator (UTM) or state plan.
Loaded Data is showing
Step 1: click on Ok
Loaded Data is showing

9. Step 2: At the bottom of right
hand side, Showing “unknown
units” means it is unable to
identify the Area of Map. There
are some process to get
identifying the area.
Step 3: For the
Step 3: For the
process of
Georeferencin
g, first of all
click on this
blank space
where lying
black arrow.
& Select the
Georeferencin
g Bar.

10. Step 4: For georeferencing its
important to set the DMS.
Means on which type of
Projection & Coordinate
system to workout
At the left hand side shows the table of
Contents. Right click on Layers then
click on properties. shows data frame
properties click on coordinate system.
Select on Geographic Coordinate
System. Scroll down and select World.

11. Step 4 Contin..: Select WGS
1984 and click ok
At the center of corner Left
click & then right click. Now
click & then right click. Now
DMS showing active

12. Showing georeferencing bar.
Step 5: Select the zoom
option
Step 5 Cont..: Zoom the
corners of Map
Step 5: select Add
control points from
the
georeferencing
bar. Now at the
center of corner
Left click & then
right click. And
then click on Input
DMS.

13. Step 6: Here we put the given Coordinates Latitude/longitude . The red
arrow shows 66 degree longitude along 00 Minutes and 00 seconds.
As well as black arrow shows 27 degree latitude with 00 Minutes and 00
seconds. After putting DMS, we select E means Eastern and N means
northern (Because Pakistan lies in Eastern and northern Hemisphere)
then click OK. Now the Same process will apply at all corners.

14. Step 7: after adding control points at all corners, Click on
Georeferencing and Click on Update Georeferencing.
Finally Georeferencing has been completed.

15. Lets Extract the Study Area from Google
Earth and Export in the Platform of ArcGis
Step 1: Open the Google Earth

16. Step 2: Select a Polygon, Add a name of Polygon like Study area,
Chose a color for polygon, Width of border line of polygon may be
increase then click OK
Step 3: Draw a
Polygon of Study
Area

17. Step 4: Save a KML file,
right click on Study area
and left click on save
place as then Select
Kml and save a file.

18. Step 5 : Showing KML on desktop. Lets export in ArcGis,
Open the ArcGis, Select Arc Toolbox, Click on conversion
tools, then click From KML and then KML To Layer.

19. Step 5 contin..: Click on Input KML file, then select the KML file
and the Click Ok

20. Step 6: at the left hand side shows table of content, its
showing Study area, Click on study area then right click on
Polygon, and data option can be seen at the fourth last,
then Click on Export Data. Now the KML file has Exported.

21. Step 7: Click on add data,
click on Add base map and
select Satellite imagery as a
base map

22. Finally The Study Area Extracted from Google Earth and
Export in ArcGis.
The End
