Technical note

JML to ICO: what carries over and what does not

A JML 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 JML 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. JML 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 JML original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
