Operational Parallel Processing in Digital Photogrammetry- Strategy and Results using Different Multi-Line Cameras

Digital sensors, providing excellent quality with respect to geometry and radiometry, are more and more replacing traditional analogue photogrammetric data acquisition. Allowing for a completely digital data flow, particularly line scanners based on the three-line principle offer new opportunities for higher productivity and for cost reduction, since automated processing of orthoimages and DEM does not depend on specific and expensive photogrammetric hardware components. With the airborne version of the HRSC (High Resolution Stereo Camera) the efficiency of this end-to-end approach to digital photogrammetric mapping has been proven within many projects during the past 7 years. The system can be applied to data of any three-line sensor since it is based on the general camera model of a multi-line camera. Thus, besides photogrammetric data products derived from imagery of the HRSC versions HRSC-A/AX/AXW, also data of LH SYSTEMS ADS40 have been processed successfully. * Corresponding author
