Correct Answer: A
Solution :
Exp. [a] Data from Indian Remote Sensing satellites are used for various applications of resources survey and management under the National Natural Resources Management System (NNRMS). Following is the list of those applications Space Based Inputs for Decentralised Planning (SIS-DP) National Urban Information System (NUIS) ISRO Disaster Management Support Programme (ISRO-DMSP) Biodiversity Characterisations at landscape level Preharvest crop area and production estimation of major crops Drought monitoring and assessment based on vegetation condition Flood risk zone mapping and flood damage assessment Hydro-geomorphological maps for locating underground water resources for drilling well Irrigation command area status monitoring Snow-melt run-off estimates for planning water use in downstream projects Land use and land cover mapping. Urban planning Forest survey Wetland mapping Environmental impact analysis Mineral Prospecting Coastal studies Integrated Mission for Sustainable Development (initiated in 1992) for generating locale-specific prescriptions for integrated land and water resources development in 174 districts. Hence, option [a] is correct.
