Convert ILI to SGI

Online GIS converters cap file size and need an upload. reaConverter converts ILI to SGI locally, whatever the size of the dataset.

Online converters too slow for your ILI files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. No command line and no scripting, unlike the usual ogr2ogr route.

Step by step

How It Works

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

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to SGI 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.
