Gratic is a vector cartography editor for orienteering and terrain maps. Standard symbol sets, pens that behave like a cartographer expects, scanned maps you can georeference, and files that open in OCAD. Nothing to install, nothing to license.

What we already have for your ground
A map starts from what somebody already surveyed. We publish both halves of what Gratic can pull in: the elevation we hold tile by tile, and every national mapping service the editor imports vector data from — with the licence and the measured reason where one is blocked.
