What is DTED file?
The Digital Terrain Elevation Data (DTED) format is a map format for terrain elevations published by the U.S. National Imagery and Mapping Agency (NIMA). The DTED files contain digital terrain models as rasters. A raster is a georeferenced grid containing a value in each one of its cells.

What do you need to know about DTED 2?
DTED2 is the basic high resolution elevation data source for all military activities and systems that require landform, slope, elevation, and/or terrain roughness in a digital format. DTED 2 is a uniform gridded matrix of terrain elevation values with post spacing of one arc second (approximately 30 meters).
What is the definition of DTED Level 1?
DTED Level I is the basic medium resolution elevation data source for all military activities and systems that require landform, slope, elevation, and/or gross terrain roughness in a digital format. DTED1 is the basic medium resolution elevation data source for all military activities and systems…
When was DTED Level 2 made available to the public?
DTED Level 2 (30m) will be available thru the 2000 STS-99 Shuttle IFSAR mission in 2001. DTED2 is the basic high resolution elevation data source for all military activities and systems that require landform, slope, elevation, and/or terrain roughness in a digital format.
How are elevation data used in DTED 2?
In accordance with the DTED® 2 specification, the terrain elevation data have been edited to portray water bodies that meet minimum capture criteria. Ocean, lake and river shorelines were identified and delineated. Lake elevations were set to a constant value.
