Data Management at Multimission Groundsegment

The Data Information Management System at the National Ground Segment of German Remote Sensing Data Center is a facility to handle earth observation products. It includes all necessary services to manage data from the availabilty after reception up to delivery to user. Functionalities like user information services, ordering control, post-processing, production control product library will be guaranteed with different system components. User information services have all external functions of data management and including guide, directory, inventory, browse and ordering. Product Library represents internal core of the data management system with inventory and archive as main components. It provides a complete and consistent reference to configured products. Archived products will be produced by different processors. Processors are connected via a unified interface which provides general functions of processor monitoring and control. The unified access for specific system components like product library or processing systems will be realized via a Java based operating tool. The universal services of Data Information Management System which were developed with CORBA technology will be used in the Multi-Mission scenario at the National Ground Segment of DLR. The interoperability between both locations of Remote Sensing Data Center is one main feature of the system. This paper shall also summarize operational aspects of data management in the frame of working package Raw Data Center of CHAMP mission.
