Digital Terrain Elevation Data (DTED)
In support of military applications, the National Imagery and Mapping Agency (NIMA) has developed standard digital datasets (Digital Terrain Elevation Data (DTED®)) which is a uniform matrix of terrain elevation values which provides basic quantitative data for systems and applications that require terrain elevation, slope, and/or surface roughness information.
