Bring files into a GIS

reaConverter takes SJ1 files to SHP a folder at a time, on your own PC, ready to be added to a GIS project and georeferenced there.

  • Convert a whole folder to SHP in one pass
  • Apply the same settings to every file in the batch
  • 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.
