OUR SOLUTION
The satellite digital images (SRTM DEM) were georeferenced with UTM projected coordinate system, datum and spheroid as WGS 1984 and zone 43 North. The mapping has been done in 1:50,000 scale. Landform classes determined by classifying the landscape using 2 TPI grids at different scales. This data is compared with existing data sets to understand the shortcomings in the present system.
