Terrain analysis is the interpretation and analysis of topographical features through Geographic Information System (GIS). Terrain is represents of cartographic of the broad scale physical regions of the study area, often based on Digital Elevation Model (DEM) i.e. elevation, slope, aspect and contour lines etc. The Gori Ganga watershed lies between the Great and Lesser Kumaun Himalayan region. The elevation of this watershed varies in between 626 m at Jauljibi to 6639 m in the snow capped mountains. The valleys are mostly steep down merging the river Gori Ganga come apart by perennial very small stream emerging through the forest covers of the river basin. For the study of terrain analysis of Cartosat-1 satellite image of time period 2008 was used. Importance of Terrain analysis studies suggest that indentifying most appropriate sites for horticulture, solar energy plant using relief, slope and aspect map of Gori Ganga watershed.Keywords: DEM, Relief, Slope, Aspect, Remote Sensing and GIS.
