(January 2016) () DTED (or Digital Terrain Elevation Data) is a standard of digital datasets which consists of a matrix of terrain elevation values, i.e., a. This standard was originally developed in the 1970s to support simulation and prediction. Terrain elevations are described as the height above the, not the. DTED supports many applications, including analyses, terrain profiling, 3-D terrain, mission planning/rehearsal, and and.

DTED is a standard (NGA) product that provides medium resolution, quantitative data in a 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) MIL-PRF-89020B, and amongst other parameters describes the resolution for each level: • Level 0 has a post spacing of approximately 900 meters. • Level 1 has a post spacing of approximately 90 meters. • Level 2 has a post spacing of approximately 30 meters. The precise spacing is defined by dividing the world into zones based on latitude, and is given in the following table: zone latitude range level 0 (arc secs) level 1 (arc secs) level 2 (arc secs) latitude spacing all 30 3 1 longitude spacing I 0°–50° (North–South) 30 3 1 II 50°–70° (North–South) 60 6 2 III 70°–75° (North–South) 90 9 3 IV 75°–80° (North–South) 120 12 4 V 80°–90° (North–South) 180 18 6 In addition three more levels (3, 4 and 5) at increasing resolution have been proposed, but not yet standardized. DTED data is stored in a format where negative numbers are.
