摘要：The aim of this work was to show the possibility of generating digital surface models on the basis of satellite stereo-pair. Test area of experiment was the central part of Warsaw. The results were compared with a DSM based on the airborne laser scanning (LIDAR). The stereo-pair was collected with very high resolution satellite system Pleiades and LIDAR data was acquired within the ISOK project. In the experiment: the influence of dense image matching the parameters was analysed,impact of control points on the correctness of scenes georeferencing pre-orientated with RPC coefficients was verified,the accuracy of DSM was assessed including outliers resulted in lower spatial resolution of satellite imagery and occluded areas. The experiment was processed in the Trimble Inpho software. The results confirmed the possibility of applying only 2-3 control points in order to obtain satisfactory results of scenes orientation and consequently DSM accuracy. In the analysis of elevation models their accuracy at the level of a single ground sample distance was achieved. For uncovered areas in case of 214 LIDAR-based control points vertical RMS was 50 cm.
