Team: Data Management

In the National Ground Segment department, the large and heterogenous geodata inventory coming from many different missions is handled by DLR’s Data Information and Management System DIMS. This distributed system (distributed both as to function and because two DFD locations are involved, Oberpfaffenhofen and Neustrelitz) offers important services and standardized, configurable interfaces for the administration of mission data. These include:

• Access management
• Order processing
• Production management
• Long-term archiving

At present (February 1, 2011), the data flows for about 35 production lines are being managed. They are designed to access a volume of mission data amounting to 240 terabytes, organized in 8.3 million files in the National Ground Segment alone.

Besides monitoring and maintaining existing production chains for the entire product life cycle (such as for GRACE and TerraSAR-X), including

• Adding new data sets to DIMS,
• Retrieving data sets from DIMS,
• Generating value-added products,
• Long-term archiving, and
• Delivery,

new processing chains are designed, configured and put into operation (such as for the EnMAP, RESA, SWACI, ASTROIDFINDER and TET missions/projects).
