Key Goals Geospatial aspects considered for the project
Identified Key Geospatial Requirements
Identify and depict more than 20 million water bodies
Undertake field visits to collect details of water bodies where information is to be validated
Segregate water bodies from agricultural fields and water-logged areas
Replace outdated maps with GIS-based digital maps
Use high-resolution satellite imagery (0.6/0.5 meter spatial resolution) for mapping activities
Integrate spatial and non-spatial information from various sub-departments into a unified system
Develop Web-enabled access of the GIS-based maps to decision-makers
