Abstract

Terrain analysis is a very important part of the study of surface processes. Although several techniques have been used historically to study terrain, the use of satellite imageries has become one of the optimum methods now. Presently there are lots of satellite imageries available for extraction of elevation features microwave optical etc. The stereo pair images have a great potentiality in the study of terrain analysis. The present study deals with the generation of Digital Elevation Model (DEM) using CARTOSAT-1 stereo data and retrieval of terrain attributes thereof for western Dehradun area. Initially the DEM is generated and the vertical accuracy was analysed. Additionally, contour and primary attributes (slope and aspect) are derived for further analysis. A three dimensional view is also generated in order to visualize the terrain perspective view.
