Earth Observations System

Earth Observations System i.e. … EOS is a crucial space infrastructure that has been instituted by the Department of Space (DOS) . The system, which was commissioned in the year 1988 with the launch of Indian Remote Sensing Satellitte, IRS-1A, has the worlds largest constellation of five satellites IRS-C, IRS-1 D. IRS-P3, IRS-P4 and TES presently in operation. It gives space-based remote sensing data in a variety of spatial resolutions and spectral bands meeting the needs of various applications. The EOS definition, development, operation and its use are co-ordinated by the National Natural Resources Management System (NNRMS) , for which DOS is the nodal agency. NNRMS is an integrated resource management system which aims for the optimal utilisation of country՚s natural resources by a relevant and systematic inventory of resource availability using EOS data with conventional techniques. NNRMS is supported at the national level by the Planning Committee of NNRMS (pC-NNRMS) , which gives guidelines for use of the system and also over-sees the development of remote sensing applications for natural resources management in the country.

The NNRMS activities are headed by ten Standing Committees, which are stated below-

  • Agriculture & Soils
  • Bio-Resources
  • Geology and Mineral Resources
  • Water Resources
  • Ocean Resources
  • Cartography & Mapping
  • Urban Management
  • Rural Development
  • Technology & Training
  • Meteorology
