National wastelands change analysis (2015-16)

National Remote Sensing Centre, Indian Space Research Organization (ISRO), Department of Space, Government of India in collaboration with different State, Central Government Departments and Institutions has completed four mapping exercises of wastelands for the country using remotely sensed satellite data on 1 : 50,000 scale.  Since the launch of wastelands mapping project, various government agencies have taken up the reclamation of wastelands particularly through the implementation of watershed programmers in the country by consulting these databases. All the wastelands mapping exercises were taken up by using various mapping methods, different map projection systems and varying datasets. All these have contributed to difficulty in depicting the wasteland changes to be shown spatially.
