Dted level 0 data download
DTED is a standard National Geospatial-Intelligence Agency (NGA) product that provides medium resolution, quantitative data in a digital format for military system applications that require terrain elevation. The DTED format for level 0, 1 and 2 is described in U.S. Military Specification Digital Terrain Elevation Data ( DTED). DTED (or Digital Terrain Elevation Data) is a standard of digital datasets which consists of a matrix of terrain elevation values, i.e., a Digital Elevation Model. The DTED format for level 0, 1 and 2 is described in U.S. Military Specification Digital Terrain Elevation Data (DTED) MIL-PRFB, and amongst. Support from select international mapping organizations was instrumental in the generation of the Level 0 dataset. The following nations have contributed data to this effort: Belgium, Denmark, France, Germany, Italy, Netherlands, Norway, Spain, and the United Kingdom. DTED Level 0 may be of value to scientific, technical.
the quality of the data appears to be better than GTOPO30; Level 0 covers only about 50% of the area covered by GTOPO30, but much of the difference is in Antarctica; surprising geopolitical holes include the UK, France, Greece, Turkey, Israel, and Korea. Level 1, aka DTED 1. post spacing is 3 arc seconds (~ meters). In addition to NGA's own DTEDs, terrain data from Shuttle Radar Topography Mission (SRTM), a cooperative project between NASA and NGA, are also available in DTED format, levels 1 and 2 (see below). The lowest resolution data is the DTED Level 0, with a grid spacing of 30 arc-seconds, or about 1 kilometer. DTED -- Military Elevation Data. GDAL supports DTED Levels 0, 1, and 2 elevation data for read access. Elevation data is returned as 16 bit signed integer . Appropriate projection and georeferencing information is also returned. A variety of header fields are returned dataset level metadata.
DTED data is available at three different resolutions, which are referred to as Level 0, Level 1 and Level 2. Each DTED file contains elevation data for a 1 degree latitude by 1 degree longitude cell. Latitudes are divided into a total of 5 zones, and the x-size of pixels differs for each zone, getting larger toward the poles. Dec 9, Abstract: The Shuttle Radar Topography Mission (SRTM) successfully collected Interferometric Synthetic Aperture Radar (IFSAR) data over 80 percent of the landmass of the Earth between 60 degrees North and 56 degrees South latitudes in February The mission was co-sponsored by the National. Since there aren't any Confidential PC's (that I've ever seen) you'll have to protect the data as if it were Secret. DTED comes in several varieties, but right now the only formats defined by formal specification are DTED 0, DTED 1 and DTED 2. Shuttle This is how Sunrise Mountain's contours look based on Level 1 data.
