Presented By :
A. Bhattacharyya, I.A.S. ,
Principal Secretary ( Land Reforms ) &
Settlement Commissioner &
Director of Land Record, Gujarat State.

3. VISION
To undertake detailed resurvey in Gujarat and create updated land records including textual and spatial information
Enabling establishment of a system which will help in the continued maintenance of updated land records
Provide ready and smooth access to required information to all stakeholders

4. Background of Land Survey in Gujarat….
Gujarat State is pioneer in the country having it’s survey records up to land parcels known as Tippans
Land Survey was carried out long ago by Britishers and old Princely States of Gujarat during to
The object of the survey was to collect Land Revenue from the owner of land in proportion to the area they held.
As per The Bombay Land Revenue Code, 1879 survey should have been conducted after 30 years of original survey.

5. Land Record Information in Gujarat
Current Scenario…..
The Government, through its organization, performs mainly two functions:
Maintenance and updation of land records (textual records, including village form No. 6 ( Hakpatrak ) and Village Form No. 7/ 12 (Satbara) and Spatial records namely village maps and field measurement books commonly known as Tippans in rural areas.-
Maintenance and updation of the textual and the spatial records in urban areas. The textual record is commonly known as Property Card.

6. Need for Advanced Survey Technology
The survey records are outdated
About % of the records have also been lost / destroyed / mutilated.
Old survey was carried out using conventional instruments available at that time – (5% Tolerance limit was allowed )
Inaccurate records
Documents in poor shape and not available at all.

10. Gujarat pioneer introducer
Gujarat is pioneer in introducing modern survey technology
ETS since
GPS since
Using this ETS technology approx villages have been re-surveyed
Using GPS technology approx hectares of land have been surveyed in Gujarat

11. GIS ready Digitized New Village Map

12. ETS & GPS
Survey Machinery

13. What is Electronic Total Station Machine
ETS is an new generation modern survey
instrument.
It is an optical theodolite combined with Electronic Distance Measurement ( EDM ) instrument and a mini computer which is helpful in collecting data of;
Distance
Angle
Height.
ETS reads, records & displays horizontal and vertical angle digitally. It stores the data in its internal data recorder. Precision of the instrument varies between 1“ to 7” (Seconds )

14. What is Electronic Total Station Machine ….
Within the overall objective of XYZ data, the following 12 kinds of detailed data are also displayed
HA = Horizontal Angle
VA = Vertical Angle
AZ = Azimuth or bearing
SD = Slope distance
HD = Horizontal distance
VD = Vertical distance
N = Northing
E = Easting
Z = Elevation
Code = Feature Code
11. Time
12. Point No = Serial Point No.

15. What is GPS ?
Global Positioning System (GPS) is satellite navigation system
It is based on a constellation of 24 satellites orbiting around earth at a very high altitude,
The system can be used to measure position of the object on the earth surface in a continuous measures
This Mapping Datum created known as World Geodetic System -84 ( WGS-84)

16. SATELLITES AVAILABLE FOR G.P.S. SERVICE

17. GPS Measurements GPS is based on satellite
We are somewhere on this sphere
GPS is based on satellite
ranging, measuring distance from Satellite
Second measurements put us somewhere on this circles & narrows down our location
By third measurements we get accurate location

18. Steps initiated by Department
More than 80 ETS & 7 DGPS provided to
field officers
RFP floated to purchase another 13 ETS &
5 DGPS
Circular issued - It is mandatory to
measure land > 10 Hectare by ETS & > 50
Hectare by DGPS
In House training facility at Deenadayal
Institute, Gandhinagar
Where 300+ surveyors are already trained on these instruments

19. Steps initiated by Department…
People who come for private survey are charged as follows:
By ETS:
< 10 Hectare Rs. 2000
For every additional Hectare Rs. 200
By DGPS:
< 5 Static Points Rs. 10,000
For every additional Points Rs
In RTK mode every point Rs. 200
500 Measurement by ETS during last 3 years
Income of Rs. 1 Crore generated
