The SRTM 90m DEM’s have a resolution of 90m at the equator, and are provided in mosaiced 5 deg x 5 deg tiles for easy download and use. All are produced from a seamless dataset to allow easy mosaicing.
This dataset contains several digital gridded data bases of global topography and bathymetry at various scales, digitized continental coastlines, gridded oceanic gravity anomalies, ocean-floor gazetteers, and digital topographic relief images in a wide variety of formats. Software or program code for PC-DOS, Macintosh, and UNIX workstations is provided to access the major topographic and geographic […]
The Global Land One-km Base Elevation (GLOBE) Project A 30-arc-second (1-km) gridded, quality-controlled global Digital Elevation Model (DEM).
1:250,000-scale Digital Elevation Models (DEM) Quadrangles that fall (either partially or completely) within a state can be located by selecting the state name
Advanced Spaceborne Thermal Emission and Reflection Radiometer High-resolution (15- to 90-meter) multispectral data from the Terra satellite (2000 to present). The ASTER On-Demand Data Gateway is used to create Level-2 (and higher) products from existing ASTER Level 1B data.
GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). GTOPO30 was derived from several raster and vector sources of topographic information. Data also available for a nominal fee ($10-$25) on DVD or CD-ROM media< ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
ATDI provides the ICS Map Server package that allows import and export of SDTS DEMs, re-projection, tiling, and generic functions for handling DEMs, Images and Land Cover files. ATDI’s interface allows users to enter a central coordinate and immediately retrieve the selected quadrangles. ATDI’s partnership with the USGS allows us to provide SDTS DEMs covering […]
In accordance with NASA policy, the USGS EROS Data Center hosts and distributes SRTM data via the USGS Seamless Data Distribution System – Enhanced. Electronic Download: Up to an area 30 degrees square of raster data (1.6 gigabytes), in 100 megabyte sized files, are downloadable at no charge.
