Fig. 3From: Evaluation of different digital elevation models for analyzing drainage morphometric parameters in a mountainous terrain: a case study of the Supin–Upper Tons Basin, Indian HimalayasContour lines have been digitized from USAMS topographical Sheet a and SoI topographical sheets b to derive the surface models in the form of DEMs. These DEMs have been used to obtain the drainage network within the these basins and the results have further been compared with the other DEMs like SRTM, ASTER and Cartosat-1Back to article page
