Technical note

ILI to GBR: what to expect from the conversion

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. GBR expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GBR 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.
