Technical note

GMT to JP2: what carries over and what does not

A GMT 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 GMT looks different in every program that opens it. The JP2 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. GMT coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. JP2 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 GMT 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 JP2 opens on any computer and any phone. reaConverter produces those from GMT in batch, entirely offline.

  • Render every file in a folder to JP2 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.
