The in-game map in Pokémon GO now looks significantly different after developer Niantic quietly updated the game to use another source for its landscapes, switching from Google Maps to an open-sourced mapping service called OpenStreetMap. The key feature of OpenStreetMap is that it allows users to submit their own data about geographic features and locations. While much of what’s included on it is similar to Google Maps, there may be other landscapes appearing in your Pokémon GO map where there weren’t any visible before.
