Map data
Map data © OpenStreetMap contributors, available under the Open Database License (ODbL) 1.0. openstreetmap.org/copyright
The vector map tiles (PMTiles) hosted by the Tu Voyage server are produced from OpenStreetMap data with Protomaps Basemaps and credit OpenStreetMap as the ODbL requires. The map style is based on Protomaps Basemaps (styles CC0, code BSD 3-Clause). When the hosted tiles cannot be reached, the map is drawn from the OpenStreetMap tile servers instead. github.com/protomaps/basemaps
Map label glyphs (Noto Sans) are loaded from Protomaps basemaps-assets under the SIL Open Font License 1.1. The web app bundles no font files; page text uses the fonts installed on the device.
