OsmAndMapCreator is a program that accompanies OsmAnd for making offline-usable data files. The most important feature is the creation of OBF files out of OSM data. Other functions allow the user to create POI, address, transit, and routing indexes from OSM files (.osm, .bz2, .pbf). OBF format is the output format and used by OsmAnd for offline rendering, routing, and search on a mobile device.
