OpenStreetMap could be a good source of a base map with a very liberal licencing issue, You'd only need to have a "Map Data (c) OSM contributors" on the map (IIRC). The main openstreetmap.org tile servers are liable to block your application if you put too much load on it, but there are plenty of companies which will sell you tile server access, (GeoFabrik, ThunderForest, Mapbox, Mapzen). |
