摘要

This paper presents how ultra high resolution remote sensing data can be used within a GIS environment for the development of urban information systems and 3D city modeling. The paper concentrates on techniques to use digital surface models (DSM's) from remotely sensed data for the creation of highly accurate digital terrain models (DTM's). DSM's can be obtained from digital stereo scanner data or from laserscanning. It can be demonstrated that DSM'S from laserscanning are better suited for 3D city analysis. Using GIS techniques, however, also DSM's from stereo matching can be improved to produce highly accurate DTM's. Together with image and GIS (e.g. digital cadastral) data, these DTM's form a 3D urban information system which can be used for pollution modeling or telecommunication planning.
