Geographic data appendix
© OpenStreetMap contributors; ODbL1.0. https://www.openstreetmap.org/copyright
Raw OSM geographic IDs/coordinates/tags retained; contributor account user/uid/changeset metadata removed. Projected data preserves the original geographic origin, north/south orientation and metre scale. Original OSM boundaries and official terrain data are unchanged by the artistic roof/planting derivative. Database extraction/reuse under ODbL is independent of marketplace artwork restrictions.
