摘要：Digital surface models can be efficiently generated with automatic image matching from optical stereo images. The Working Group 4 of Commission I on "Geometric and Radiometric Modelling of Optical Spaceborne Sensors" provides a matching benchmark dataset with several stereo data sets from high and very high resolution space borne stereo sensors at http://www.commission1.isprs.org/wg4/ . The selected regions are in Catalonia, Spain, and include three test areas, covering city areas, rural areas and forests in flat and medium undulated terrain as well as steep mountainous terrain. In this paper, digital surface models (DSM) are derived from the Cartosat-1 and Worldview-1 datasets using Semiglobal Matching. The resulting DSM are evaluated against the first pulse returns of the LIDAR reference dataset provided by the Institut Cartogr`afic de Catalunya (ICC), using robust accuracy measures
