Technical note

What changes when you convert DIM to STEP

DIM is made of pixels and STEP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a STEP container.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as STEP opens on any computer and any phone. reaConverter produces those from DIM in batch, entirely offline.

  • Render every file in a folder to STEP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • 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

DIM to STEP 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 STEP files?

STEP file contains Standard for the Exchange of Product Data (ISO 10303). STEP format is a widely used by popular CAD software.
