Technical note

How DIM and IGS differ in practice

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. How good the result is depends almost entirely on the DIM 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 DIM and end up in IGS. 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 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.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

DIM to IGS Conversion

What are DIM files?

DIM (Digital Image MAP) is a metadata-driven format for satellite imagery, developed by the French space agency CNES together with SPOT Image to describe products from the SPOT and Pléiades missions. A dataset consists of an XML file with the .dim extension and one or more image files stored beside it, usually as GeoTIFF or JPEG 2000 rasters, while earlier versions used BIL and TIFF files. The XML document describes the product identification, acquisition date and time, sensor and satellite parameters, geometric processing level, coordinate reference system, band names and order, radiometric calibration values, sun and viewing angles, and the image dimensions. Related files may hold preview images, quality masks, and rational polynomial coefficients for sensor model correction. The format is applied to panchromatic, multispectral, and pan-sharpened scenes at several processing levels, from primary to orthorectified products, and the .dim file acts as the entry point to the whole dataset.

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 DIM to IGS?

Yes! reaConverter instantly converts .dim 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 DIM 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. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
