Big data management in Earth Observation: the German Satellite Data Archive at DLR

The German Satellite Data Archive at the German Aerospace Center (DLR) has been managing large volume Earth observation data for more than two decades. Hardware, data management, processing, and user access, as well as long-term preservation are under one roof and interact closely in the payload ground segment (PGS). Several examples will demonstrate how Earth observation data life cycles benefit from close interaction between the PGS and the application scientists and from operational experience gathered over time.
