Abstract :
Cartosat-1 is stereo satellite launched in May 2005 for analysis of Indian terrain. Most effective application of cartosat-1 data is creation of Digital elevation models from stereo pair. Cartosat-1 operated in different modes like Normal Mode, Reverse Pitch Mode & Wide Mono-mode. Pitch bias plays significantly important role in detection of modes of cartosat-1. DEMs are generated for Pune area by using stereo images belonging to different modes of cartosat-1. The accuracy of generated data evaluated with the help of reference DEM available for Pune Area. Rational polynomial coefficients (RPC) used for Photogrammetry & DEM generation. Generated DEMs are compared by using different parameters like Standard deviation, Slope, Aspect. By combining both modes we tried to remove blunders as well as errors occurred during DEM generation. Fusion of Cartosat-1 DEM with reference DEM also carried out. DEMs generated from above stereo pairs are of type Relative DEMs i. e DEMs without GCPs.
