Technical note

What changes when you convert DT1 to DXF

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. DXF expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. How good the result is depends almost entirely on the DT1 going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as DT1 and end up in DXF. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to DXF with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

Someone gave me a disc with a single .dxf file that just wouldn't open. After struggling with it, I consulted some tech-savvy friends who recommended reaConverter. The conversion took about 20 seconds flat, and now I can easily view everything in PDF format!

My laser engraver only accepts DXF, but my designs come in AI and SVG. reaConverter handles the conversion seamlessly – and preserves all the paths and cut lines. I've processed over 500 designs with zero failures. Absolutely indispensable.

FAQ

DT1 to DXF Conversion

What are DT1 files?

DT1 is the file extension for Level 1 of Digital Terrain Elevation Data (DTED), a standardized elevation product described in the MIL-PRF-89020 specification of the U.S. National Geospatial-Intelligence Agency (NGA). Each file represents a one-degree by one-degree geographic cell and contains terrain heights sampled at a regular interval of 3 arc-seconds, equal to approximately 90 to 100 meters at the equator. Level 1 sits between the coarser Level 0 (.dt0) and the finer Level 2 (.dt2) products, and serves as a common choice for regional terrain analysis, flight planning, line-of-sight studies, and mapping at medium scales. The file starts with header records that identify the cell, its origin, and its accuracy, followed by the matrix of elevations. The format is a long-established standard in defense, aviation, and civil geospatial work.

What are DXF files?

DXF (Drawing Exchange Format) is a format associated with AutoCAD, a popular program used for computer-aided design by engineers, architects and other professionals in the field of building design and construction. The DXF format was developed in the early 1980s by Autodesk with the purpose of increasing the interoperability between AutoCAD and other CAD or advanced image design programs. It supports 2-dimensional and 3-dimensional drawings, and can be opened using a wide array of image processing programs.
