This presentation based upon implementation of forest right act using GPS .

1. What is GPS?
The Global Positioning System (GPS) is a space-
based satellite navigation system that provides
location and time information in all weather
conditions, anywhere on or near the Earth where
there is an unobstructed line of sight to four or
more GPS satellites.
The GPS project was developed in 1973
and It became fully operational in 1994 (
U.S. Department of Defense (DoD).
Global Navigation Satellite Systems
(GNSS)
NAVSTAR
USA
GLONASS
Russians
Galileo
Europeans

2. How GPS works?
 At least 3 satellites required for 2D fix

3. Three SV ranges known
20,000 Km radius
22,000 Km radius
21,000 Km radius

4. Gps vs land survey
Surveying or land surveying is the technique, profession, and
science of accurately determining the terrestrial or three-
dimensional position of points and the distances and angles
between them. These points are usually on the surface of the
Earth, and they are often used to establish land maps and
boundaries for ownership or governmental purposes.

5. Present land survey
equipments
 Gps /dgps
 Total station
 Theodolite ……

6. Compare between gps and
plain table

7. Gps in forest resource
mapping

2. Different color sketch pen
3. Drawing paper
4. Cadastral map
5. Topo sheet
6. Field note
7. Pen
8. Pencil

8. VILLAGE MERKUL

9.  1.Arrangement of FRC meeting with elder
village persons

10.  2.Preparation of customary village boundary
sketch map

12. 3.Gps point taken at field (both triangulation points
and customary landmarks

13. Record of gps points
Signature of FRC members and submission of gps
data field note.

14. 4. transfer of gps data into gis software using arcgis

15.  5.Scanning of cadastral maps & topo sheet
1. Conversion of paper map into digital
format for use in gis

16. 6. final preparation of village map with customary
boundary by using gis software

17. 7.boundary on Google earth
