The case of PIMS: Image information mining in a SAR data ground segment

摘要

Conventional ground segments for spaceborne SAR instruments collect raw SAR data and convert them into standard image and interferometry products. Typical examples are the routine generation of complex, detected, or geocoded image products. These data are archived and accessible via user interfaces linked to browsing tools that use catalogues with quicklooks, metadata, etc. On the other hand, during the last years, considerable effort has been spent in the design of data mining systems and specific image information mining techniques that allow the retrieval of images from large archives based on their content. We will describe how the PIMS ground segment architecture combines product generation, archiving, and cataloguing with image information mining functions permitting automated feature extraction as well as interactive data analyses by users of various disciplines.
