Technical note

DT0 to IGS: what carries over and what does not

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. IGS 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. A line in a DT0 image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the DT0 does not survive as colour in the IGS.

Map Data Workflow

From map data to a working drawing

Converting DT0 to IGS usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • Convert every layer in a folder to IGS 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

DT0 to IGS Conversion

What are DT0 files?

DT0 is the file extension for Level 0 of Digital Terrain Elevation Data (DTED), a gridded elevation product defined by the U.S. National Imagery and Mapping Agency, now the National Geospatial-Intelligence Agency (NGA), in the MIL-PRF-89020 specification. A file of this type covers one degree of latitude by one degree of longitude and holds elevation values at a post spacing of 30 arc-seconds, which corresponds to roughly one kilometer on the ground. Higher levels of the same series use the .dt1 and .dt2 extensions, with spacings of 3 and 1 arc-seconds. Each file starts with header records that describe the cell origin, the data set identification, and the accuracy of the data, followed by the elevation grid. DTED is widely used in military, aviation, and civil mapping applications, and Level 0 data is publicly available.

What are IGS files?

The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.

Can reaConverter convert DT0 to IGS?

Yes! reaConverter instantly converts .dt0 to .igs with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For DT0 to IGS it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline.
