Digital Terrain Elevation Data .DTED File Description

Surfer imports digital terrain elevation data or DTED data sets.

Digital Terrain Elevation Data .DTED are grids originally produced by the United States National Imaging and Mapping Agency (NIMA). The files contain latitude/longitude coordinates with the Z units in meters.

There are multiple "levels" of DTED files. Level 0 files .DT0 are 1-degree square blocks with 30 arc-second spacing, similar to GTOPO 30 files. Level 1 files .DT1 use three arc-second spacing. Level 2 files .DT2 use one arc-second spacing.
