Description:
Abstract: The Shuttle Radar Topography Mission (SRTM) was a partnership between NASA and the National Geospatial-Intelligence Agency (NGA). Flown aboard the NASA Space Shuttle Endeavour (11-22 February 2000), SRTM fulfilled its mission to map the world in three dimensions. The USGS is under agreement with NGA and NASA's Jet Propulsion Laboratory to distribute SRTM elevation products derived from the C-band radar data. SRTM utilized interferometric C-band Spaceborne Imaging Radar to generate elevation data over 80 percent of the Earth's land surface.
Global SRTM data at a resolution of 1 arc-second have been edited to delineate and flatten water bodies, better define coastlines, remove spikes and wells, and fill small voids. Larger areas of missing data or voids were filled by the NGA using interpolation algorithms in conjunction with other sources of elevation data. The SRTM 1 Arc-Second Global data offer worldwide coverage of void filled data at a resolution of 1 arc-second (30 meters) and provide open distribution of this high-resolution global data set.
Purpose: SRTM elevation data of the Earth's land surface are available with data points posted every 1 arc second for global coverage.
Supplemental_Information: Gobal coverage is between 60 degrees North and 56 degrees South latitude.
Raster size is 1 degree tiles. The data are expressed in geographic coordinates (latitude/longitude) and is horizontally referenced to WGS84 and vertically referenced to EGM96 Geoid.
Formats:
1. DTED - Digital Terrain Elevation Data is a standard mapping format designed by the NGA. Each file or cell contains a matrix of vertical elevation values spaced at regular horizontal intervals measured in geographic latitude and longitude units. DTED is a trademark of NGA.
2. BIL - Band interleaved by line is a simple binary raster format with accompanying ASCII descriptor files. The BIL integer format is recommended for software packages that do not support floating-point data.
3. GeoTIFF - Georeferenced Tagged Image File Format is a TIFF file with embedded geographic information. This is standard image format for GIS applications.
