How It Works

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

Technical note

How LOS and JXL differ in practice

LOS is not a map but a correction grid. Each cell holds the small offset needed to move coordinates from one datum to another, or the height of the geoid, the surface that turns a GPS height into a height above sea level. Survey and GIS software applies it silently during a coordinate transformation. Rendered as JXL, it becomes a smooth picture of those offsets, useful for documentation or teaching, while the transformation itself still needs the original LOS. LOS carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXL 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 LOS 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 JXL opens on any computer and any phone. reaConverter produces those from LOS in batch, entirely offline.

  • Render every file in a folder to JXL 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.
