Technical note

What changes when you convert DT2 to IGS

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. Lettering in the image is traced as shapes, not recognised as text. Every character arrives as an outline that can be scaled and edited like any other geometry, but not retyped, restyled or searched, and no font is attached to it. Titles and callouts on a scanned drawing usually have to be typed again in the IGS if they need to stay editable.

Map Data Workflow

From map data to a working drawing

Converting DT2 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.

FAQ

DT2 to IGS Conversion

What are DT2 files?

DT2 is the file extension for Level 2 of Digital Terrain Elevation Data (DTED), the high-resolution tier of the elevation series standardized in MIL-PRF-89020 by the U.S. National Geospatial-Intelligence Agency (NGA). A file of this type covers a one-degree by one-degree cell with a post spacing of 1 arc-second, about 30 meters at the equator, which makes it suitable for detailed terrain work such as viewshed modeling, slope analysis, route planning, and flood simulation. It is the most detailed of the three standard levels, following the .dt0 and .dt1 products. The content is organized as header records with identification and accuracy information, followed by a regular grid of elevation values for the cell. Because of its fine sampling, Level 2 files are considerably larger than those of the lower levels.

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.
