Convert DTM files online for free
The converter easily converts your DTM file to various formats - free and online. No Media Player or extra software needed.
The converter also works in reverse, so you can convert other GIS formats to DTM with high quality output.
A .DTM file generally functions as a Digital Terrain Model, a specialized GIS format used to store ground surface elevation data (x, y, z coordinates). These files are critical in civil engineering for calculating cut-and-fill volumes, designing road alignments, and analyzing hydrology.
The real problem with .DTM files is that the extension is a "generic container" used by multiple competing software vendors with incompatible internal structures. A .DTM exported from RIB Software (formerly STRATIS) is structurally different from one created by Teledyne PDS or Bentley InRoads. Consequently, they rarely open in standard CAD viewers and often require the specific, expensive enterprise software version they were created in.
To make this data usable in standard workflows, you should convert these files to non-proprietary exchange formats. For AutoCAD or MicroStation drafting, convert to DXF or DWG. For 3D modeling and visualization in Blender, convert to OBJ. for strict GIS analysis, GeoTIFF or DEM are the industry standards for archiving elevation data.
Use Convert.Guru to open and convert your DTM file.
Users also converted TIF, STR, SAV, RVT, NWD, TMDX, INP, CATPART, VMO, DEM, XML, DXF and DWG files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DTM converter.
