30m SRTM DEM now available for Africa

To empower local authorities to better plan for the impacts of severe environmental changes such as drought, glacial retreat, flooding, landslides, coastal storm surges, agricultural stresses, and challenges concerning public health, today the National Aeronautics and Space Administration (NASA), the National Geospatial-intelligence Agency (NGA), and the U.S. Geological Survey (USGS), as part of an ongoing commitment to open data and international data sharing through the inter-governmental Group on Earth Observations, will release a collection of higher-resolution elevation datasets for Africa.

Until now, elevation data for Africa were freely and publicly available only at 90-meter resolution. The 30-meter resolution datasets being released are based on data collected by sensors designed by an international partnership and carried on the U.S. Space Shuttle—resolve to 30-meters and will be used worldwide to improve environmental monitoring, climate change research including sea-level rise impact assessments, and local decision support. These datasets are being made available via a user-friendly interface on USGS’s Earth Explorer website. With a commitment from the Secure World Foundation, and in collaboration with the Committee on Earth Observation Satellites, USGS, NOAA, and NASA plan to offer online training and regional workshops to further enable users to take advantage of these data resources.
