摘要：With the transition from analytical to digital photogrammetry digital image data has become more important. Today digital image data acquisition is mainly based on scanned aerial film. The user is facing the problem to appraise the radiometric and the geometric quality of digital image data. If a scanning service provider will be mandated with the film scanning, a detailed specification of the project is requested. The German bureau of standards is currently working on a new set of standards for photogrammetric products. ( DIN 18740 ) A new standard " Requirements for scanned aerial images" is available as a draft. It describes on which technical parameters of photogrammetric scanners the user has to pay attention. This can have a big impact on the image quality. Furthermore it is described on how then user can specify and check the radiometric and geometric image quality. An attachment with a template for bidding of scan contracts is available for the user. This form can be used to specify the scan parameters, the data format, the meta data and quality reports. A second standard about the quality of digital images acquired directly with digital aerial cameras is currently in preparation. This standard will cover line sensors and frame sensor cameras. This papers reflects some ideas and fundamental knowledge concerning these standards and their usage
