Architecture of a new generation of remote sensing ground segments

摘要

Due to the huge volume and high complexity of remote snesing data, the management of image archives demands high level representation of information. Augmentation of hte data with meaning is a key issue for the success of query processes, and has to include the model of user's understanding. The information retrieval process is split up into two steps: objective information extraction and semantic representation. These concepts are applied for hte design of a new generation of remote sensing ground segment systems.
