| Abstract: | This paper describes different methods of DEM generating from SPOT HRS (High Resolution Stereoscopic) Stereo Data.From Comparisons of the DEM from HRS stereoscopic and that without ground control points (GCP) with the reference DTM,the accurary of DEM derived from SPOT HRS is estimated.It gives an assessment of the DEM generating from HRS.At the same time,this analysis proves the possibility to get DEM using HRS stereo data in the project of serveying and mapping in the west of China. |
