Large format digital cameras for aerial survey of geospatial information

(DMC) of Z/I Imaging (Intergraph) and is operating this system since February 2006. Up to November 2006 there was about 250 hours of aerial survey flights flown and about 25.000 images processed. Additional experiences exist with other large format cameras. This paper will first give some information about the technical and financial processes of evaluation of the digital large format camera for aerial surveys. In the second part, the configuration of the system as it was chosen by Hansa Luftbild will be explained. The emphasis will be laid on the installation of the system in different kind of survey planes. The handling of the amount of data and the image post-processing are challenging tasks which demand a strict workflow and an integration into the complete project management workflow. Solutions for intermediate quality checks have been established and some are still under preparation. Finally, experiences about geometric and radiometric quality and calibration procedures can be demonstrated in the real production environment. RÉSUM
