What is a .DTED file?
DTED (Digital Terrain Elevation Data) is a military-standard grid of ground heights.
- Did you know
- DTED began as a US Defense Mapping Agency format for terrain elevation.
- The format is specified by the US military standard MIL-PRF-89020, with named levels for increasing detail.
- Files begin with fixed UHL, DSI and accuracy header records, followed by elevations as 16-bit big-endian integers.
- What Analyser reads
- Inspect geospatial and GIS files without a map: TopoJSON, OpenStreetMap XML, Esri Shapefile siblings (SHP/SHX/DBF/PRJ/CPG), world files, GML, NMEA GPS logs, IGC flight logs, MapInfo TAB/MIF, GDAL VRT, PMTiles, DTED terrain, Esri ASCII grids and SRTM .hgt - surfacing CRS/EPSG, feature/record counts, bounding boxes and elevation ranges.

- Depth of analysis
- .DTED is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .DTED file
- Drag a .DTED file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
