Abstract:
| Mapping of the Earth’s surface from satellite images is a continuing application in remote sensing, which has been distinctly pushed with the increasing availability of very high-resolution image data. In most of the missions, stereo images can be acquired making 3D mapping from space very attractive, as high accuracy and level of detail become feasible from such data. In this paper, several case studies are presented, which have been applied to stereo pairs acquired by the SPOT sensors as well as the very highresolution Ikonos sensor. As an extension to standard stereo mapping, a 3D mapping approach which makes use of multiple image coverage is presented. For this work, image triplets including multi-sensor data sets have been used to extract 3D topography information and to generate digital surface models. The benefit of this extended approach is comparatively assessed with respect to results achieved from standard stereo mapping. |
