USGS Digital elevation models (DEMs) are arrays of regularly spaced elevation values referenced horizontally either to a Universal Transverse Mercator (UTM) projection or to a geographic coordinate system. DEMs are used often in geographic information systems, and are the most common basis for digitally produced relief maps. Digital Terrain Models (DTMs) show the bare earth, after all surface features have been digitally removed. The Caspian Sea border, the Africa depression and some areas from the Netherlands, all under sea level were corrected. EEA Plone KGS 21.4.22. EU-DEM is a digital surface model (DSM) of EEA member and cooperating countries representing the first surface as illuminated by the sensors. Digital Surface Models (DSMs) include all surface elevations from terrain, vegetation and man-made features, such as buildings and infrastructure. A "global DEM" refers to a discrete global grid. 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°20'N. NASA only needed 11 days to capture Shuttle Radar Topography Mission (SRTM) 30-meter digital elevation model. 33405 Talence, France ABSTRACT This paper presents a fast algorithm for smooth digital elevation model interpolation and approximation fromscattered elevation data.
