he German Satellite Data Archive (D-SDA) at the German
Aerospace Center (DLR) has been managing largevolume Earth-observation (EO) data in the context of EOmission payload ground segments (PGSs) for more than
two decades. Hardware, data management, processing, user

pertise are under one roof and interact closely. Upcoming
EO-mission PGSs benefit as much from the comprehensive
expertise, close interaction, and integrated infrastructure as
do in-house scientific application projects requiring access,
processing, and archiving of large-volume EO data. Using a
number of examples, we will demonstrate how EO data life
cycles benefit from the proximity of data management and
application scientists and from the extensive operational experience gathered over time.
