OpenStreetMap
Map data © OpenStreetMap contributors.
OpenStreetMap data is available under the Open Database License (ODbL) 1.0: https://www.openstreetmap.org/copyright
Map data, places, opening hours and routes shown in TourIts are derived from OpenStreetMap. If TourIts creates or publishes a derived database from OpenStreetMap data, that database is made available under the ODbL as required. You can improve the map for everyone at https://www.openstreetmap.org.
Map search, places and routing services
- Overpass API (public instance at overpass-api.de): querying OpenStreetMap data for places.

- OSRM (Open Source Routing Machine) on the FOSSGIS server at routing.openstreetmap.de: travel time and distance calculations, BSD 2-Clause License.
All use data © OpenStreetMap contributors. TourIts currently uses these public instances within each service’s usage policy and will move to self-hosted or paid servers as usage grows.
Map tiles and rendering
- MapLibre Native / MapLibre React Native: BSD 2-Clause License.
- Map style and vector tiles: OpenFreeMap (https://openfreemap.org), based on OpenStreetMap data: “© OpenMapTiles © OpenStreetMap contributors”.
