Licences that ask for more than a credit
- OpenStreetMap (ODbL 1.0). Places, paths, stations and many layers come from OpenStreetMap. Terrena's database mixes them with other sources, so the OpenStreetMap-derived part is a derivative database under the ODbL, and the map, cards and tiles are produced works credited to OpenStreetMap contributors. On request we provide that derivative data, or the method that makes it from OpenStreetMap, under the ODbL ([email protected]). Live aircraft from adsb.lol are ODbL too and are shown, not stored.
- Wikipedia text (CC BY-SA 4.0). Place summaries are Wikipedia's opening sentences, unchanged, with a link to the article and the licence. They stay under that licence; Terrena's own text does not become CC BY-SA by sitting next to them.
- Wikidata (CC0). No conditions; credited anyway.
- Wikimedia Commons and Mapillary photos. Each picture keeps its own licence and author, shown with it; a photo under a share-alike licence is shown as it is, never edited into something new.
