About Mobac

Mobile Atlas Creator (MOBAC) creates offline map atlases from online map sources, including OpenStreetMap-based maps, for GPS handhelds and phone apps such as TrekBuddy, AndNav, OruxMaps and OsmAnd. It can also export an individual map as a single PNG image with a MAP calibration file for OziExplorer.

Atlases can combine multiple layers, map sources and zoom levels, with custom tile size and PNG/JPG format, saved profiles, local tile caching and multithreaded downloading through an HTTP proxy. It requires Java Runtime Environment 11 or higher installed and a high-speed internet connection while running.
