STATE REMOTE SENSING APPLICATION CENTRE,
• SRSAC earlier known as “Aerial Photo Interpretation
Laboratory (APIL)” established in 1979 as part of Desert
Development Programme to assist soil and water
Conservation Planning in the State.
• In 1985 looking to multi-disciplinary utility of the Remote
sensing Technology, the laboratory was transferred with staff
to State Department of science and Technology and renamed
as “State Remote Sensing Application Centre (SRSAC).”
• Generation of number of database related to natural resources for
developmental planning activities in the state using remote sensing
techniques (Aerial Photo Interpretation and Satellite data
interpretation both visually as well as digital mode).
• To generate data bank consisting of temporal and spatial data
products and to generate information system on natural resources.
• To interact with various user agencies for the formulation and
implementation of Remote Sensing Projects for development
• To undertake short term and long term experimental and operational
remote sensing studies to identify, and manage various natural
resources such as soil, water, forest, agriculture, minerals,
settlement, town planning, drainage, roads and geology for
monitoring changes due to natural calamities such as drought, flood
and also to evaluate land use changes.
• Human Resource Development in the field of remote sensing by
organizing short term appraisal courses / seminars or workshop /
exhibitions on remote sensing application for the user departments,
agencies, NGO’s and students.
• To interact with National Remote sensing Institute like National
Remote Sensing agency (NRSA), Hyderabad, Space Application
Centre (SAC), Ahmedabad, Regional Remote Sensing Service Centre
(RRSSC), Jodhpur to carry out joint projects.
Database Created for Various Line Departments:
Centre has created larger number of database on natural resources of
the state on requisition from various user departments, agencies, etc.
as a part of nation wide policy of department Space by participating in
technology transfer strategy.
Few among these are –
Watershed Development and Soil Conservation Department :-
Watershed Delineation :
• All natural resources development planning is based on watershed
• This requires spatial distribution and characterization of watershed at
• Watershed delineation has been done using satellite data as well as
aerial photographs for all the Panchayat samiti blocks of the State.
• Using remote sensing inputs characterization up to micro level depicts
slope direction, extent, land use characterization – cultivated area,
wasteland, drainage density, based on per cent cultivated area and
drainage density priotisation has also been done.
These have proved to be valuable data base for taking up watershed
development works, based on which huge funding is being received from
Government of India under various schemes.
Watershed Management Information System (WMIS) :
Under World Bank aided “Watershed Development Programme
A computerized GIS based “Watershed Management Information System”
on ARC / INFO Platform has been developed at the Centre.
The model comprises of extent, nature characterization of watershed, land
ownership, erosion extent, cropping pattern, irrigation status, inputs for
development various treatment model, etc.
It also incorporates query based retrieval of any information about watershed
including characterization and development.
Water Harvesting Structures –
By virtue of stereoscopic view through aerial photographs taking existence of
firm banks along stream, sufficient submergence area, less than 2 % slope at
site, medium to heavy textured soils in submergence area into consideration
suitable sites for structures locally known as Anicut have been identified.
Panchayat Samitiwise Master Plan for all the such sites prepared for entire
In all 2120 such sites were proposed-
Rajasthan, especially north western part of the state is prone to occurrence of
frequent droughts, which, consequently has adverse affects on the economy and
living standards of habitants of the area. Rainfall is meager as well as erratic,
Hence, whatever the quantity of water available through rains, is of significant
importance so all attempts are made to conserve for drinking and growing
crops on conserved soil moisture.
Khadeen is most appropriate water conservation device for this area to conserve
runoff water right in cultivated fields to have a rabi crops.
Number of such sites have been identified in different part of the State.
BLOCK - KOLAYAT
DISTRICT - BIKANER
Ravinous Area Delineation –
In east and south eastern part of Rajasthan, along Chambal and its tributaries
large tract of ravinous area exist.
Ravines have very adverse effect on the agro-economical activities of the
area. Conversion of fertile cultivated lands into un productive ravine land.
These are known to provide good hiding place for dacoits.
Its spread had been enchroaching adjoining good arable land and thus area
under ravines has increased considerably over the years.
To check their expansion correct distribution and extent of ravines is
Delineation of spatial distribution of ravines have been delineated and their
depth wise classification has also been done.
District covered under this are Kota, Jhalawar, Baran, Bundi, Sawai
Madhopur, Karauli, Dausa, Bharatpur, Dhaulpur, Jaipur and Jhunjhunun..
This is an important database for reclamation and monitoring expansion of
growth so as to increase agricultural productivity.
Besides all above work for –

Irrigation Department :
Master Plan for Lift Irrigation sites -
South east Rajasthan has flow of periniel rivers, which have water
availability during rabi crop season also.
The water can be used for irrigation in Rabi season also, by lifting from
Under a special scheme organization sponsored project, using two season
satellite data site selection for suitable sites for Lift Irrigation was done.
Panchayat Samiti wise Master Plan of Lift Irrigation Sites prepared for 102
Panchayat Samiti blocks of the state.
This data base is being intensively used under community lift Irrigation

at the part of Jaisalmer and Bikaner districts.
National (Natural) Resources Inforamtion System (NRIS)
It is a Department of Space Collaborative Project under which district level
planning database on natural resources and infrastructure resources in GIS
environment through computer being generated.
NRIS is visualized as a network of GIS based nodes covering the districts
and states and the entire country.
These nodes will be the repositories of resource information in the spatial
domain and will provide vital inputs to decision making at district level.
The Prime objective of NRIS Project is to provide information to planners
for sustainable development both for land and waer resources in the district.
The detailed objective of this project are to create digital database of thematic
map on 1:50,000 scale for the district nodes and link them through suitable
network; integrate thematic information in GIS environment to draw local
specific action for land / water resources and socio economic development in
the district / State.
And generate query shall for data retrieval and generation of action plans
interactively for decision making.
