How It Works

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

Technical note

Before you convert GRC to ICO

GRC carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. ICO has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the GRC original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to ICO 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.
