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
