![]() ![]() ![]() Together these data releases constitute the world's first high-resolution, near-global elevation model. Forthcoming releases will include Africa-Arabia and Australia plus an "Islands" release for those islands not included in the continental releases. Previous releases covered North America and South America. This Eurasia segment includes 5,940 tiles, more than a third of the total data set. The data are being released to the public on a continent-by-continent basis. A degree of latitude measures 111 kilometers (69 miles) north-south, and a degree of longitude measures 111 kilometers or less east-west, decreasing away from the equator. The data were processed into geographic "tiles," each of which represents one by one degree of latitude and longitude. SRTM flew on board the Space Shuttle Endeavour in February 2000 and used an interferometric radar system to map the topography of Earth's landmass between latitudes 56 degrees south and 60 degrees north. This release includes data for most of Europe and Asia plus numerous islands in the Indian and Pacific Oceans. The colored regions of this map show the extent of digital elevation data recently released by the Shuttle Radar Topography Mission (SRTM). ![]()
