Digital Elevation Model represents elevation in two dimensional varying raster. It provides significant analysis of the terrain characteristics and planning. Availability of high-resolution satellites helps extraction of DEM at different global scales from the stereo imagery. Cartosat-1 is an along track sensor which acquire stereo data acquired continuously with fore and aft cameras. Stereo data including Rational Polynomial Coefficients (RPCs) is used to generate DEM based on standard Rational Polynomial Model. This paper evaluates the DEM generated from Ames Stereo Pipeline (ASP) for Carosat-1 stereo pair with Shuttle Radar Topography Mission (SRTM) DEM. The accuracy of the DEM extracted from ASP is tested with the standard SRTM DEM. The performance analysis shows that correlation of AMES DEM with SRTM shown 0.97 and RMSE of order 13.64m. The AMES DEM has shown high correlation and low RMSE values with the standard SRTM DEM.
