Denotes the angle between the path oriented image and the map oriented image for this ASTER scene. Dear Sir ASTER is a 15 m resolution data and SRTM is 3 arc second (90m) so certainly ASTER is better, we have developed set methodoology and was quite successful. A digital elevation model (DEM) is a 3D computer graphics representation of elevation data to represent terrain, commonly of a planet (e.g. ... Digital Elevation Model is a 3D representation of elevation data to show Earth`s terrain. Your browser is out of date. In this study, the quality of DEMs acquired by SRTM ver.3 and ASTER ver.2 is evaluated. GDEM Black & White Map Further analysis: The shift is not homogeneous.
