ComputaMaps’ free terrain data available on https://www.computamaps.com now incorporates data from the Shuttle Radar Topography Mission. The eleven day NASA/NIMA mission, which was carried out in February 2000 aboard the Space Shuttle Endeavor, collected over 12 terabytes of interferometric RADAR data covering approximately eighty percent of the Earth’s surface. This project represents no less than a revolution in the mapping of the Earth in three dimensions. ComputaMaps’ co-Managing Director Justin Hyland notes that the “benefits of SRTM data for global RF planning, among many, many other fields, will be tremendous. For the first time planners will have access to highly accurate elevation data over huge areas of the globe where previous mapping was incomplete, often inaccurate, or did not exist.” ComputaMaps’ free geodata is available in UTM projection WGS84 datum in PlaNET format. In addition, ESRI BIL (ARC/INFO .hdr) header files are included for those users wishing to employ the data in other applications.
