摘要：The objective of this paper is to assess the Digital Elevation Model (DEM) mosaicing accuracy. The Indian Remote Sensing satellite Cartosat–1 acquires the data in along track stereo mode with a ground resolution of 2.5 m and swath of 27.5 km. Hence the generation of DEM for a larger area covering more than 27.5 km width requires the mosaic of multiple DEMs. This paper deals with a study of the Drum Mountains terrain in USA. As the study area sprawls across the paths, it facilitates the evaluation of the DEM mosaic. The area of interest is covered by two scenes covering in two adjacent paths 1389 and 1390. Since GPS points covering the area of interest are not available, the ASTER DEM has been used as a reference for evaluation of DEM mosaic using two different techniques
