State Remote Sensing Application Centre

The State Remote Sensing Application Centre (SRSAC) was established in the year 1996 and now functioning as an independent organisation under the Department of Science and Technology, Government of Arunachal Pradesh and acts as the nodal centre for Remote sensing application programmes in the state.

State Government vide Notification No SRSAC/18/2016-17, Dated Itanagar, the 29th Feb’2016 has designated SRSAC, Itanagar under the Department of Science and Technology, Government of Arunachal Pradesh as “Nodal Agency” for promoting Remote Sensing (RS), Geographical Information System (GIS) and Global Positioning System (GPS) application solution to all the offices including public sector undertakings, Govt Departments, Government Societies as per their requirement.


The main objective of SRSAC is to utilize the advanced state-of-art Remote Sensing and GIS technologies for inventory, mapping and monitoring of natural resources and planning for their sustainable development and also for effective rural and urban developmental planning in the state and taking up research/projects addressing various environmental problems and hazards in the state.


  • To generate geospatial datasets and create user friendly applications (through web-enabled distribution tools) for government departments to serve as an effective tool for decision making, planning, implementation and monitoring purposes
  • To integrate state-of-the-art remote sensing (RS), geographic information system (GIS), and global positioning (GPS) technologies with on-the-ground knowledge of ecosystems and natural resource management to address relevant issues.
  • To transfer knowledge and skills to the community, academicians and government departments through education, outreach and training.
  • To Provide core geospatial dataset (administrative boundaries, road, railway, and major settlement etc.) to all the departments in the state.



Since its inception, the centre has been providing latest state-of-the-art technology i.e. Remote sensing and GIS (Geographical Information System) services for various developmental activities in the state. The activities includes Land and water resources inventory, Mapping and monitoring of natural resources, Rural and urban area survey and mapping, Cadastral surveys, Topographical surveys , Land and water resources mapping for urban and rural area development, Land use / land cover mapping, Wasteland mapping, monitoring and change analysis,  Ground water prospect mapping, Road alignment studies, Snow cover & glacial mappings for climate change studies, Potential area identification for horticulture and sericulture development, Digital Elevation Model (DEM) generation, Hazard zonation mapping of earthquake, landslides and flood, Topographical surveys of catchment areas, Land degradation mapping using state-of-the-art Remote Sensing and GIS technologies.etc.

The centre has been providing single window geospatial support services time to time to various user departments (both central and state government organizations), NGOs, individuals, Public leaders, DCs, BDOs, Circle Officers, DRDA officials, teachers and students of colleges and universities. SRSAC has extended its services in formulating project proposals to different departments, individuals in delineating administrative boundaries, forest and wild life sanctuary boundaries. Wasteland maps prepared by the centre have been used extensively by various departments, NGOs, and Project Directors of DRDAs. It may be mentioned here that SRSAC has also extended its services to several DCs and CO’s for delineating the administrative boundaries of their respective districts and circles.

SRSAC is going to establish a “State Data Repository / Hub” to maintain all RS & GIS inventories, maps and data generated by SRSAC and other departments and agencies. The Ministry of DoNER has already initiated activities to strengthen the state RS centres with State Data Repository (SRD), which will be equipped with server based workstations with needed bandwidth. It is going to be a common platform for geospatial data generated by SRSAC, other state government departments and agencies. Besides the SRD will have instant link with ISRO centre like NESAC, NRSC and SAC. Necessary infrastructural support will be provided by DoNER Ministry, GoI.

The centre is going to establish State Bhuvan portal with the support of Department of Space, Govt. of India, which will enable SRSAC to upload the geospatial data of its own and the  geospatial data owned by other state government departments / agencies.

SRSAC is going to take up satellite based project monitoring and geo-tagging of developmental projects in Arunachal Pradesh.


During 2017-18, SRSAC has completed important projects like Geo-morpholgical and lineament mapping of Arunachal Pradesh, Ground water project zonation mapping, Mapping and monitoring of shifting cultivation areas, Application of RS and GIS for identification of suitable areas for Sericulture and Horticulture development, Monitoring of snow and glaciers of Himalayan region. Besides the centre has been rendering support for demarcation of any new administrative units like circles, blocks and district in the state with maps.

In collaboration with the Department of Space, the SRSAC has initiated project like North Eastern Spatial Data Repository (NESDR) to maintain all RS & GIS inventories, maps and data generated by SRSAC and other departments and agencies.


 A few important projects are : Satellite monitoring and geo-tagging of development projects in Arunachal Pradesh, Generation of maps and web publishing of geo-database of orchid potential sites of Arunachal Pradesh, RS, GIS and GPS technology application for Updation of administrative maps of Arunachal Pradesh, Organising State level awareness programme on “Promoting use of Space technology in governance and development in Arunachal Pradesh”, Flood vulnerability studies in selected catchment areas in Arunachal Pradesh, Wetland mapping on larger scale in selected districts of Arunachal Pradesh using high resolution satellite data, Generation of GIS based Information System on various public utilities and infrastructure in Itanagar capital complex using Space technologies. Besides SRSAC is going to implement a project “Satellite image based Experimental Flood Forecasting Activity” in collaboration with NESAC, DoS, Govt. of India.
