Abstract :
The Shuttle Radar Topography Mission SRTM mapped the Earth´s surface in two frequencies - C-band and X-band. This paper presents the SRTM/X-SAR products, the processing and archiving facility as well as the procedures on how the products will be made available. The raw data volume stored online within the robot archive of DLR´s Remote Sensing Data Center (DM) will be about four TBytes. The processing of this amount of data requires the use of high performance parallel computers scheduled and supervised by a new control and information system. The DEM production line is split into three subsystems the scanning and screening, the SAR as well as interferometric processing and finally the elevation derivation and mosaicking procedure. An online catalogue accessible via web browser provides all information required for a product selection
