DGPF Project

Within this paper, results of a test on the evaluation of the most recent photogrammetric digital airborne camera systems are presented. This project was initiated by the German Society of Photogrammetry, Remote Sensing and Geoinformation (DGPF), based on data from 12 different digital sensor systems flown in a well-controlled test site. The main topics of the evaluation phase are the analysis of geometric accuracy and sensor calibration, the radiometric performance including on-site radiometric calibration and multi-spectral land classifications, the performance of photogrammetric Digital Surface Model (DSM) generation, and the potential of manual stereoplotting from digital images. Within this paper, only results obtained at the Institute of Photogrammetry (IFP), Universitaet Stuttgart will be presented, comprehensively proving the high performance of digital camera systems and processing. The IFP served as the pilot center and additionally concentrated on the investigation of camera geometry and the image based generation of height data.
