News and Events
Andhra Pradesh is the only State in the country which
has opened up Cadastral Surveys and building up accurate, fully
computerised Land Information System.this will help to arrive at a viable,
speedy, economical and accurate procedure for rebuilding uptodate Cadastral
records on a larger scale, in ready to maintain Digital Format.
Government in their G.O.Ms.No 626 Rev. (SS) Dept.
Dt. 24.8.98 have accorded administrative approval for a total cost of
Rs. 68.70 lakhs for conducting Experimental Resurvey in 3 Districts.ie.
Karimnagar,Guntur & Chittor.Subsequently the cost of the Project was worked
out to be Rs. 1,02,55,000. This includes cost of Resurvey, Computerisation
and providing outputs by the Private Agencies and procurement of Hardware &
Software for the 3 selected Mandals. This is a State Scheme.
The work has been entrusted to 3 Private agencies on per-
acre rate contract basis and the work Began in Nov.2001.
|| Name of Agency
||Name of District / Mandal
|| Total Area
||M/s Alpha Geo
||Karimnagar Dist./ Manakondur
||M/S Speck systems
||Guntur Dist /Tadepally, Mangalgiri, Thulur
||Chittoor Dist /V.Kota
The salient features of this approach are:
Thus after the end of this project,
- Recording of measurement data for each land holding through ground
measurement techniques strictly with reference to enjoyment on ground,
by entrusting the work to the field staff of this department .
- Building up of the land register through local enquiry.
- Generation of field maps and village maps from field data downloaded into
computers from total stations theodolite .
- Integration of the graphic record in an appropriate manner with the title
- The advantage of having the data for the entire village in digital format
is that its updation and monitoring are quite efficient and easy. The incorporation
of all changes in title and boundary is rendered less cumbersome and prompter.
To this extent the record generated through the proposed resurveys can be
brought into maintenance faster and guarded against obsolescence for relatively
longer periods of time.
- there will be digital land records available pertaining to villages
taken up in this project.
- The records are easily accessible and copies can be given when requisitioned
by farmers .
- These records can be easily updated as and when new sub-divisions are created
- The data can be used by various departments for planning new projects as
the vertical control (spot levels ) available without extra effort.
- GIS can be developed for these villages integrating survey numbers data ,
Electric lines data ,Roads data ,Telephone lines ,crops data, Water channels
data , trees ,drainage system ,Schools , bore wells M P H S data and and HDS
Computerisation of Basic Records
The Government in their G.O Ms No. 718 Rev. (SS) Dept.
Dt. 06.10.1999 have accorded administrative sanction for computerisation
of basic Records i.e. Field Measurement Books and Village Maps in all
villages in Kuppam Asembly Constituency.The cost of this Project is Rs.55
Lakhs with cent percent Central Aid.
The work has been entrusted to M/s Vision Labs. The
work is in progress and has been taken up in the following Villages:
|| Villages to be Digitised
|| No. of FMBs
|| No.Of Sub-Divisions
|| No. of Village Maps
Future action plan for continuation of the programme of Digitization/
Computerizationof Cadastral Survey Maps.
A Project report on Digitization/Computerization of basic
survey records ie. FMBs and Village Maps with a cost of Rs14.75
cores in 278 Mandals covering one Mandal from each Assembly
Constituency of 22 districts (Excluding Hyderabad(urban) district
as records were already Digitization/Computerization) was prepared
and submitted to Government of Andhra Pradesh for onwards
submission to Government of India for seeking 100% central aid.
The details are as under.
Dynamic Command Area Crop-Monitoring System (D-CACS)
Government of Andhra Pradesh issued orders Vide G.O.Ms.No.238
Rev.(P&C) Dept dt.30.3.2001, sanctioning a Pilot Project on Dynamic
Command Area Crop Monitoring System (D-CACS) with a cost of Rs.52.00
lakhs for implementation by Chief Commissioner of Land Administration
(CCLA) and Andhra Pradesh State Remote Sensing Application Centre.
The objective of D-CACS is to evolve a dynamic, season
specific and modern system by employing Remote Sensing and Geographic
Information System (GIS) technologies to monitor the irrigated and
cropped extents in the Command Area of different irrigation Projects
in Andhra Pradesh with a fair degree of accuracy, to facilitate
efficient collections of water rates as well as macro level agricultural
The methodology to put the new system into operation involves
the following activities:
- acquisition of current satellite imagery separately for the Rabi and Kharif
seasons for the respective command areas, showing the irrigated areas under
the chosen " Command Area" with standing crops.
- Generation of digital database for the constituent Cadastral maps of he revenue
villages comprised in the respective command areas.
- Digital superimposition of the Cadastral data on to the geo-coded satellite
imagery and showing the location of the areas under standing crops within
the cadastral framework of each revenue village.
- Supervised classification of the satellite data and digital extraction of
survey number wise irrigated and un irrigated cropped areas for each revenue
- Linkage of landholding title data computerised by the National informatics
Centres of respective centres.
- Validation of the Sy. Nos and land holding wise cropped areas through joint
azmoish at the village level.
- Firming up of the land holding wise cropped areas and generation of final
statistics for each revenue village to facilitate water yield collections
and crop yield computations.
To start with the Nagarjuna Sagar Project (NSP)with an area of
8.95 lakhs Ha and Sri Ram Sagar Project (SRSP) with an area of 4.11 lakh
Ha, comprising a total of 10.06 Ha in an estimated 2000 revenue villages
have been taken. The coverage is at present limited to Paddy & Sugar Cane
The broad division of tasks among the various agencies
responsible to implement the project is

||Procurement of Satellite imagery from the experimental area
||Generation of Digital Data base for the Constituent Cadastral
Maps of thr maps of the villages comprised in the respective command areas.

Experimental Resurvey in Telengana Region
Project Reports are being prepared for Experimental
Resurvey on similar Lines for Villages wherein more
than 75% of FMBs/Village Maps are in torn Condition.
The Proposals would be sent for the approval of
Government.These new projects are proposed to be taken
up by the Dept. itself by forming Core groups and giving
them training in handling the concerned Software like
Autocad, arc Info, Arc view etc;
The estimated cost of Resurvey of the villages
where 75% Tippans (FMBs) missing in Telangana Area is
Continuation of Digitisation/Computerisation
of Cadastral Survey Maps
A Project reports on Digitization/Computerization of
basic survey records ie. FMBs and Village Maps with a
cost of Rs14.75 cores in 278 Mandals covering one Mandal
from each Assembly Constituency of 22 districts (Excluding
Hyderabad(urban) district as records were already
Digitization/Computerization) was prepared and submitted
to Government of Andhra Pradesh for onwards submission
to Government of India for seeking 100% central aid.
This Project Report costing Rs. 15 crores is proposed
for 100 % GOI assistance from Ministry of Rural Development.
Results of Resurvey And Computerisation
- Electronic Preservation, maintenance and updating of records at Mandal
& District level.
- Fast retrieval, storage of huge data, small storage place and easy accessibility
- Relatively permanent and online updating.
- Information on network at Mandal & District & State level to facilitate universal
- Survey & land records updated.
- No need for periodical resurvey of entire State.
- Avoid litigation between public and government & between private parties
