India's wasteland atlas India has been instituted and information is used for planning various developmental programmes. A digital data base is also now being formed.

National Drinking Water Mission: Under the sponsorship of the Department of Drinking Water of the Ministry of Rural Development, maps showing prospective zones of ground water occurrence and recharge are being prepared on 1: 50, 000 scale ill six states (Andhra Pradesh, Karnataka, Madhya Pradesh, Chhattisgarh, Kerala and Rajasthan). So far 930 maps have been prepared out of the 1800 maps required. The maps are integrated with GIS data base and identify areas and sites for locating borewells. Coastal Studies: Information on Coastal wet lands, land forms, land use, shore line changes, etc. have been mapped on 1: 250, 00011: 50, 000 scales for the Ministry of Environment and Forests. Coral reef maps on 1: 50, 000 scale for Gulf of Kutch, Gulf of Mannar, Palk's Bay, Lakshadweep and Andaman & Nicobar islands have been established. Mapping of the characteristics between High Tide Line (HTL) and Low Tide Line (LTL) and land use features for a strip of 500 m from HTL, on 1: 25, 000 scale, under Coastal Regulation Zone has also been carried out. The maps are used for preparing coastal zone management plans and for designing regulations on construction along HTL. Use ofIRS-P4 (OCEANSAT) Data: An end to-end task of using IRS-P4 data for oceanographic, marine-atmospheric and coastal environmental applications has been taken up. Different agencies like Department of Ocean Development, Indian Meteorological Department, National Institute of Oceanography, Central Marine Fisheries Research Institute, etc. besides several State Departments are participating in this task. The Ocean Colour Monitor (OCM) of IRS-P4 provides data on Chlorophyll distribution and primary productivity for locating potential fish zones, sea surface velocities, suspended sediment movement, coastal landforms, coral reefs, etc. The Multi-frequency Scanning Microwave Radiometer (MSMR) on board the satellite gives data on humidity over oceans, water vapour content, winds, rain rate, fluxes, sea ice, etc. Disaster Management: Landslide Hazard Zonation (LHZ) Mapping: Landslide Hazard Zonation (LHZ) mapping on 1: 25, 000 scale is being carried out for all core pilgrim and tourist routes in the Himalayan region in Uttaranchal and Himachal Pradesh. Database has been formed for the entire 2000 km long corridor and LHZ maps have been made.

The routes covered include: RishikeshRudraprayag-Chamoli-Badrinath, RishikeshGaumukh, Rudraprayag-Okhimath-Kedarnath, Chamoli-Okhimath and Pithoragarh-Malpa, all in Uttarancha1; Shimla-Manali, Shimla-Sumdo and Dalhousie-Brahmaur in Himachal Pradesh. The maps are used by State Public Works Departments (PWD), Border Roads Organisation and some NOOs. Gujarat Earthquake: The space based imagery along with aerial remote sensing provided inputs to the Gujarat State Administration during the Earthquake in January 2001 in terms of locating the worst affected towns, to assess the changes in the terrain features and damage assessment. The satellite news gathering terminal was also moved from the Space Applications Centre and establish at Bhuj which was the only link till February 2, 2001 to co-ordinate rescue and relief operation.

National (Natural) Resources Information System: A information infrastructure developed around GIS for providing an ease in the conceptual planning and decision making at District-State-National level is being came into influence for the Planning Authorities. Already NRIS has been used for 30 districts and four state nodes. The NRrs consists of 22 spatial layers and 8 non-spatial layers in the context of natural resources as well as socio-economics.

3 broad categories of wastelands are stated below:

  1. Barren rocky sheet rock.

  2. Gullied areal ravines.

  3. Mining Industrial wastelands.
