For the tiles here, these areas have been filled and corrected from the best available alternative sources, using the method described on my voidfill page. SRTM data, in HGT format, can be downloaded from here, but for some mountain and desert areas there are no-data (void) and phase unwrapping error areas, and there are no SRTM data north of 60☂0'N. The downloadable 3 arc second 1°x1° Digital Elevation Models on this site are mainly based on data collected by the 2000 Shuttle Radar Topography Mission. Interactive coverage maps supplied by Christoph Hormann.įor more information, see the continental links below. The whole world is now on this site at 3 and 15 arc second resolutions.ĭata developed and uploaded in Scotland by Jonathan de Ferranti.
