摘要：The Digital Surface Model (DSM) of world coverage is increasingly coming from data from satellite systems. This involves systems operating both in optical and microwave ranges (radar interferometry InSAR). Most recently,new solutions have emerged for stereoscope imaging in such satellite systems as the Japanese satellite PRISM and Indian satellite CARTOSAT-1,which can be characterized by two coupled forward and backward cameras with a pixel size of 2.5 m. This paper outlines characteristics of the Indian satellite,which has been operating since May 2005,and which has been designed for generation of accurate DSM from stereoscope images. This is the next system from Indian Remote Sensing (IRS) family,working solely in the panchromatic range. In the framework of a program conducted by the Department of Space,Government of India, a research team in Poland conducted an experiment of DSM generation for an area situated southwest of Warsaw. With a use of dGSP technique,they designed and measured the photo-points (ground control points - GCP). The polynomial method (RPF) for the description of image geometry was also applied. The generation of a Digital Surface Model was conducted in LPS and PCI environments and the influence of the number of GCP on the accuracy of the generated DSM was analyzed. The obtained errors in altitude of the control points (CP) were 1.5 m using 9 GCP. The obtained results are above expectations. The CARTOSAT-1 System may constitute an economically attractive source of data for the generation of global range DSM.
