Didger 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.
