摘要:The present paper deals with the accuracy potential of SPOT-5 HRS satellite imageries for DEM generation. The goal is to derive a DEM from the along-track stereo data of the SPOT HRS sensor and to assess the accuracy by comparison with DEM data of superior quality. Following a brief description of the instrumentation and the data set used, the quality of the DEM generated from these imageries is assessed in several steps. For georeferencing of the stereo pair of images, some ground control points (GCPs), extracted from digital vector maps of the study area. A DEM of 10 meter grid size was generated from those images. And finally, the resultant DEM was compared with an existing and sufficiently accurate reference DEM of the study area. As can be seen below, the findings and results are very promising
