A DT0 file is a Digital Terrain Elevation Data (DTED) file that contains Level 0 information to study terrain elevation data. Elevation data is uniformly spaced in a DT0 file and can be read by popular GIS programs such as ESRI ArcGIS Pro, TatukGIS, Blue Marble Geographic Global Mapper, and Pitney Bowes MapInfo. DT0 files are mostly used by scientific and technical communities to study the slope, elevation, and surface roughness of global terrains.
DT0 file format is similar to DT1 and DT2 file types but with less granularity.
DT0 File Format
DT0 files are save as binary files to disc. These can be read using many GIS applications. DT0 files can be merged into a File Geodatabase Raster Catalog that can be used to create one big mosaic.
