Cartosat Digital Elevation Model (DEM) to Drainage Extraction Techniques of Vrushabhavati basin of Karnataka, India Using Remote sensing and GIS Techniques.

Digital Elevation Model (DEM) on of important concept for delineating the surfacial features like structures (Folds, Joints and Lineaments) and Drainages are also one of the surfacial features through software techniques and analysis using Arc-GIS 10.2.1 software and Erdas-14 Software delineating the drainages from Cartosat DEM The necessary base maps for morphometric analysis carried out through GIS Mapping using SOI Topographical Sheets of the area at scale 1:50,000. The required GIS maps are drainage map, surface water body map, drainage order map, drainage sub-watershed map. In the study area vrushabhavati area by Toposheet observed First order 762, Second Order 159, Third order 38, Fourth order 9 and Fifth order 3 and Deleneating the Drainage Pattern of using Cartosat DEM 710 First order, Second Order 131, Third Order 30, Fourth Order 7 and Fifth Order 2 this is the comparitivity between Toposheet and Digital Elevation Model Using Remote Sensing and Geographical Information system.
