Technical note

GEOJSONL to ICO: what to expect from the conversion

A GEOJSONL file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same GEOJSONL looks different in every program that opens it. The ICO render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. GEOJSONL coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. ICO is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the GEOJSONL original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to ICO 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.
