How It Works

reaConverter offers the fastest, simplest solution for converting your DEM files into STEP without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

What changes when you convert DEM to STEP

DEM 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 DEM 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.
