U.S. Releases Enhanced Shuttle Land Elevation Data – NASA Jet Propulsion Laboratory.
Elevation data at the highest possible resolution from NASA’s Shuttle Radar Topography Mission in February 2000 are now being released for the first time for most of the African continent.

High-resolution topographic data generated from NASA’s Shuttle Radar Topography Mission (SRTM) in 2000, previously only available for the United States, will be released globally over the next year, the White House announced today. The announcement was made at the United Nations Heads of State Climate Summit in New York.
This initial public release of topographic data for Africa will help empower local authorities to better plan for the impacts of severe environmental changes such as drought, glacial retreat, inland flooding, landslides and coastal storm surges. Datasets covering the remaining continents will be made available within one year, with the next release of data focusing on Latin America and the Caribbean.
Lower-resolution SRTM topographic data having 90-meter (295-foot) pixels were released publicly in 2003 for many parts of the world, providing a global standard for many applications. The new data increase the detail to 30-meter (98-foot) pixel spacing, now revealing the full resolution of the world’s landforms as originally measured by SRTM. Read the rest of this entry
