How It Works

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

Technical note

How DIM and STP differ in practice

DIM is made of pixels and STP 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 an STP container.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see DIM data has GIS software. reaConverter renders it to STP for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to STP 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.
