IRS Data Products

Earth Observation (EO) from satellite platforms is proved to be an indispensable tool for natural resources mapping, monitoring and management, including environmental assessment at global, regional and local levels. This is particularly due to multi-platform, multi-resolution, multi-temporal and synoptic viewing capabilities from space platforms. Remote Sensing Satellites were commissioned as an integrated facility with Data acquisition and Product generation at Shadnagar complex of National Remote Sensing Centre (NRSC), formerly known as National Remote Sensing Agency (NRSA), for Landsat MSS data reception, way back in 1979. With the availability of data from the operational Indian Remote Sensing Satellites (IRS), from 1988, NRSA started disseminating IRS satellite data to the user community.

Over a period of time, the Indian EO programme has evolved into a fully operational system providing rich data services to the user community. Data from EO satellites support wide range of information needs of the user community for better understanding of the Earth system at global to local scale and helps in providing information on natural resources, agricultural, water, land use, forests, weather, natural disasters and so on. Today, India is one of the leading countries in the world for the operational use of satellite remote sensing for National development. The Indian EO System is widely acclaimed around the world for its application driven approach. The system operates under a unique national level institutional framework, National Natural Resources Management System (NNRMS) established under the aegis of the Planning Commission.

With a host of payloads onboard the series of Indian Remote Sensing (IRS) Satellites, the Indian EO system is providing varieties of operational services to the user community in the country. The Planning Committee of NNRMS (PC-NNRMS), chaired by Member (Science), Planning Commission, oversees various aspects of EO technology utilization in the country and provides necessary guidance for implementation of application programmes of national importance. The nine high-power Standing Committees, constituted under NNRMS, provides the impetus for operational use of remote sensing and allied technologies in different thematic areas, through respective Ministries.

Government has adopted a comprehensive Remote Sensing Data Policy (RSDP) for the acquisition and distribution of satellite remote sensing data - from Indian and foreign satellites for civilian users in India. The Policy comprehensively covers guidelines for satellite data acquisition and distribution in the country and also for licensing the IRS capacities to other countries. Department of Space is the nodal agency for implementing the Policy. In particular, the Policy streamlines the distribution of high-resolution data to Government users; private users involved in developmental activities with government and other private/ academic/ foreign users. The RSDP is envisaged to be a step towards making transparent procedures for satellite data distribution, including those from high resolution imaging systems, and, without being restrictive. This has helped in regulating the process of data distribution, so that the Indian users are not denied access to this valuable information - which has become a main¬stay of the natural resources management activities of the country. Through this policy, the National Remote Sensing Centre (NRSC) of the Indian Space Research Organization (ISRO)/ DOS is vested with the authority to acquire and disseminate all satellite remote sensing data in India, both from Indian and foreign satellites.

The NRSC has wealth of images from Indian and foreign remote sensing satellites in its archives and also has the capability to acquire data pertaining to any part of the globe on demand. NRSC also supports, through ANTRIX, establishment of International Ground Stations and International reseller network to receive, process and market IRS data products globally.

NRSC provides end-to-end solutions for utilization of data for natural resources management, geospatial applications and information services. NRSC facilitates several remote sensing & GIS application projects for natural resources and environmental management catering to food security, water security, energy security and sustainable development. NRSC is also providing single window, disaster management support services through the Decision Support Centre. NRSC also implemented Bhuvan, a Geoportal of Indian Space Research Organization, showcasing Indian Imaging Capabilities in multi-sensor, multi-platform and multi-temporal domain. This Earth browser gives a gateway to explore and discover virtual earth in 3D space with specific emphasis on Indian Region, thematic data dissemination, Pocket Bhuvan and EO data down loads.

The satellite data are acquired, processed and disseminated to the user community as standard/ value added products to the Indian and International user community. In order to minimize the turn-around-time from data acquisition to product delivery and to provide near real time data for critical applications, Integrated Multi-mission Ground Segment for Earth Observation Satellites (IMGEOS) has been conceived and is being implemented at Shadnagar Complex of NRSC.
