Abstract
Abstract. 10 years after the first introduction of a digital airborne mapping camera in the ISPRS conference 2000 in Amsterdam, several digital cameras are now available. They are well established in the market and have replaced the analogue camera. A general improvement in image quality accompanied the digital camera development. The signal-to-noise ratio and the dynamic range are significantly better than with the analogue cameras. In addition, digital cameras can be spectrally and radiometrically calibrated. The use of these cameras required a rethinking in many places though. New data products were introduced. In the recent years, some activities took place that should lead to a better understanding of the cameras and the data produced by these cameras. Several projects, like the projects of the German Society for Photogrammetry, Remote Sensing and Geoinformation (DGPF) or EuroSDR (European Spatial Data Research), were conducted to test and compare the performance of the different cameras. In this paper the current DIN (Deutsches Institut fuer Normung - German Institute for Standardization) standards will be presented. These include the standard for digital cameras, the standard for ortho rectification, the standard for classification, and the standard for pan-sharpening. In addition, standards for the derivation of elevation models, the use of Radar / SAR, and image quality are in preparation. The OGC has indicated its interest in participating that development. The OGC has already published specifications in the field of photogrammetry and remote sensing. One goal of joint future work could be to merge these formerly independent developments and the joint development of a suite of implementation specifications for photogrammetry and remote sensing.
Highlights
THE DIN STANDARDS COMMITTEE NA005-03-02 “PHOTOGRAMMETRY AND REMOTE SENSING”Several terms related to film/filter techniques of analogue photogrammetry have been eliminated
The German Institute for Standardization (DIN) has a long tradition in defining technical terms and in establishing quality requirements of products or procedures
The standards in photogrammetry and remote sensing are arranged in terms and definitions and in a series of quality requirements of procedures and outputs: The basic standard DIN 18716 “Terms and definitions in photogrammetry and remote sensing” from the mid-90s has been completely revised
Summary
Several terms related to film/filter techniques of analogue photogrammetry have been eliminated The former differentiation between picture and image which discriminated between the airborne and the spaceborne products has been updated to “image” and “image data” to acknowledge the basic identity of digital sensor systems. While the standards DIN 18740-1 and -2 dealing with analogue aerial cameras and analogue/digital conversion using film scanners have been withdrawn, the enduring standards refer to orthophoto production (DIN 18740-3), digital cameras (DIN 18740-4), land use classification (DIN 18740-5), and further new data products The goal of these activities was always to support users in defining their requirements in invitations for tender and service contracts by making available specifications for products and services.
