3. Place data
Open place data
OpenStreetMap
Open place data is © OpenStreetMap contributors and available under the Open Data Commons Open Database License (ODbL) 1.0.
Copyright and license ↗Structured records
Wikidata
Structured Wikidata records used for source identity and attribution are made available under CC0 1.0 by Wikidata contributors.
Licensing information ↗Celvion’s photography guidance and exact editorial camera positions are separate original material even where a nearby place name or source entity is identified from open data.
Online place records supplement the bundled catalog. Celvion Scout suppresses matching source identities and conservative name/location matches so the same place is not shown twice; bundled and user-saved records take priority.
When the supplemental catalog is enabled, each OSM-derived record retains its element ID, source URL, retrieval date, visible © OpenStreetMap contributors attribution, and ODbL 1.0 link. OSM records remain separate from Wikidata records licensed under CC0 1.0.
4. Terrain data and services
Celvion Scout combines several terrain sources for approximate horizon planning. Availability, terms, and attribution requirements remain controlled by each provider. Follow the provider links for the current authoritative notices.
