Abstract
The primary goal of Cartosat-1 mission is to generate, archive and disseminate seamless Digital Elevation Model (DEM) to facilitate the Remote sensing users and cartographers. The production approach identified for generating CartoDEM is through processing based on Ground Control Points (GCPs) using Augmented Stereo Strip Triangulation (ASST) software system. DPGS-NRSC has generated and disseminated 10 m CartoDEM covering India and surrounding countries, part of south- west Asia and in the process of generating DEM covering Australia. 30 m DEM is ported on Indian EO portal Bhuvan for visualization and free download. To explore the improved performance of the DEM, we carried out comparative quality analysis of CartoDEM data with 2.5, 5 and 10 m resolutions generated in operational mode. This study has confirmed the enhanced performance of 2.5 m CartoDEM in terms of hydrological, terrain category and contour analysis. This geospatial input is one of the decision making tools for understanding spatio-temporal variations and better management.
