Shuttle Radar Topography Mission (SRTM) Data

Shuttle Radar Topography Mission (SRTM) data are Earth surface remote sensing data recorded from space in the STS-99 Shuttle Radar Topography Mission (SRTM) in February 2000. They serve to create a uniform, high-resolution digital elevation model (Digital Elevation Model DEM) of the Earth's surface. With SRTM even impassable regions of the earth were recorded and measured within 11 days. Covered areas between the 60th northern and 58th southern latitude, due to the orbit of the orbit due to the poles are not included in these databases (Source: Wikipedia). This data can be placed in FreeAirMap as a transparent overlay over the map data. The transparency is freely configurable.
