Step by step

How It Works

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

Map Data Workflow

Move GIS data between formats

Data deliveries rarely arrive in the format a project runs on. reaConverter takes REL to MIF on your own PC, file after file, with nothing uploaded.

  • Convert an entire delivery folder to MIF in one run
  • Produce several formats from the same source for different teams
  • Leave the originals untouched and write the results to a folder of your choice
  • 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.
