摘要:Airborne pushbroom systems for the direct acquisition of digital imagery enable the simultaneous capture of high quality3D and multispectral information of a scene. The combination of geometric and radiometric information should improvetasks like DTM generation – usually solely based on stereo imagery – and landuse classification, which is traditionallyrestricted to the interpretation of spectral information. Within this paper these assumptions are confirmed utilizing datasetsof the DPA (Digital Photogrammetric Assembly), a scanning airborne sensor which records simultaneously high spatialresolution stereo and multispectral image. Since the surface reconstruction and ortho image generation from airbornescanner imagery, which is a prerequisite for the proposed approach is different to standard procedures using full frameimages, this process will be described in the first part of the paper. Afterwards the benefits of a combined evaluation ofstereo and multispectral data will be demonstrated for two tasks, the generation of Digital Terrain Models and the landuseclassification for thematic mapping
