> I'm assuming OpenStreetMap provides the vector data. Yes and no. The OSM project provides a database dump. You can download it all ( https://planet.openstreetmap.org/ https://planet.openstreetmap.org/ ). But it's not really in a format that you can draw maps from without processing (look at https://switch2osm.org/ https://switch2osm.org/ to see how). > OpenStreetMap doesn't charge to use their service commercially iirc The map images on openstreetmap.org are run by unpaid volunteers, in a donated server space, and is for the OSM project and mappers to use. If some group starts hammering the service, then they'll block you, commerical or non-commerical is not relevant. There is no guarantees of service. If you want guarantees, pay someone :)
