ACQUISITION OF URBAN BUILDING MODELS WITH THE USE OF DIGITAL PHOTOGRAMMETRY, IMAGE PROCESSING AND GIS

摘要

The applications in data capture for Geographic Information Systems are increasing with the technological development in stereo photogrammetry. Evaluations of urban building models which can be used for radio network planning as well as for various types of imission tests are especially important at present. The creation of urban building models at digital level is a process which includes the generation of building polygons, orthophoto production, the measurement of a digital terrain model and a digital relief model. Up-to-date building models for the eleven largest German cities can be obtained from PHOENICS in the data depth and resolution as described.
