Data sources & attribution

WalkSage guides are built on open data. That data comes with licenses, and the licenses come with obligations — this page is where we meet them, and where you can trace where our facts come from.

OpenStreetMap

Place locations, paths, and map-derived data are © OpenStreetMap contributors and available under the Open Database License (ODbL) v1.0. OpenStreetMap is a collaborative project — if you spot a mapping error, the best fix is contributing it upstream.

Wikidata

Structured facts about places (identifiers, coordinates, relationships) come from Wikidata, whose structured data is published under Creative Commons CC0. Where a point of interest has been reconciled to a Wikidata entity, we link its Q-id directly on the guide page.

Wikipedia

Background reading and historical context draw on Wikipedia, whose text is available under CC BY-SA 4.0. Articles we relied on are cited as sources on the relevant guide pages.

Open-Meteo

Climate tables use data from Open-Meteo, available under CC BY 4.0. Each climate table links the specific data source it was built from.

How we handle unverified facts

Every stage guide shows the date its data was verified. When a fact cannot be verified against a source — a stage distance, a crowd level, a coordinate — the page renders an honest placeholder ("see stage map", "not yet measured", "pending verification") instead of an invented number. The same rule applies inside the WalkSage app, where every claim carries a confidence rating and cited sources.
