摘要：GSI (Geographical Survey Institute) is researching to apply high-resolution satellite imagery to topographical mapping. Previous studies with IKONOS and SPOT5 show its effectiveness. QuickBird has the highest resolution among the commercial satellites. According to prior studies, QuickBird mono image with DEM gave good results for horizontal accuracy and discrimination. We confirmed the accuracy of 3D model from QuickBird stereo imagery is suitable for topographical mapping and the shift contained in the 3D model was decreased with a simple correction. In this study, we try to generate the digital surface model from QuickBird stereo images and compare the results with products from aerial photographs and aerial laser scanner. We also generate the orthorectified images from QuickBird images and evaluate the quality
