SRTM X-SAR DEM

This map contains elevation products at a spatial resolution of approximately 25 m x 25 m covering the globe between latitudes 60° North and 58° South. These products were generated from data collected by the German-Italian interferometric X-band radar system (X-SAR) onboard the Space Shuttle Endeavour during the Shuttle Radar Topography Mission (SRTM) between February 11 and February 22, 2000.
