Evaluation of Worldview-1 Stereo Scenes and Related 3d Products

This paper describes the first investigations carried out at ETH Zurich on the very-high resolution optical satellite sensor WorldView-1. The dataset includes a stereopair acquired in 2007 over Morrison, Colorado, USA. The pair consists of a quasi-nadir scene with mean GSD close to 51cm and an off-nadir scene, with GSD up to 73cm. We show our first results of exploiting Digital Surface Modeling (DSM) and of evaluating the potential of the images for 3D city modeling using the software CyberCity-Modeler, in terms of level of detail. Here, special attention was dedicated to the DSM generation using the software package SAT-PP (Satellite Image Precision Processing) and the accuracy assessment by visual and quantitative analysis with respect to reference data derived from aerial images.
