SRTM30_PLUS (2014)[править]
combined bathymetry and topography model .. the 30_PLUS version offers 0.5 arc-min (900 m) resolution. The bathymetric data in SRTM30_PLUS stems from depth soundings (SONAR) and from satellite altimetry... Over land areas, SRTM30 data from the USGS is included. SRTM30_PLUS provides background information for Google Earth and Google Maps.
Ground heights[править]
- by USGS in SRTMv4 - 90m, in SRTM DLR - 25m.
- ASTER GDEM - ЦМР на основе радиометра ASTER, установленного на борту спутника Terra. Пространсвенное разрешение 15 метров.
