Geosciences Applications

Satellite data are useful for selection of sites for identification hydroelectric dams. High resolution IKONOS data were used for mapping on 1:5,000 scale in Middle project in Arunachal Pradesh. Detail study was carried out using IKONOS data around dam site with emphasis on shear zone identification. Structural weak zones (e.g. faults and shear were also mapped which helped to identify locations of dam axis. Similar study has been carried out in Tawang Valley for dam site suitability using Cartosat-1 data.Oil pipeline alignment studies have been carried out for IOCL. Reservoir  sedimentation studies are also being carried out for NHPC for Teesta stage IV dam.
