| Topographic data acquired during the Shuttle Radar Topography Mission (SRTM), in February 2000, flew onboard Space Shuttle Endeavour. The SRTM radar contained two types of antenna panels, C-band and X-band. C-band data processed at the Jet Propulsion Laboratory and X-band processed and distributed by DLR.
