How It Works

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

Technical note

What changes when you convert NAT to PPM

NAT carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. PPM 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 NAT original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to PPM 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.
