Data sources

Terns brings together live data from several places so you can choose where to stop. This page lists each source, what Terns uses it for, and the licence it is shared under. Thank you to everyone who collects and shares it.

Services, food, shops and facilities

Addresses, outlets, fuel brands and facilities come from OpenStreetMap, © OpenStreetMap contributors, available under the Open Database Licence. Names, roads and operators of motorway services are checked against Wikipedia's lists of UK motorway service areas (CC BY-SA 4.0).

EV chargers

Charging networks, charger counts and speeds come from Open Charge Map (CC BY 4.0). Each stop shows when its charger details were last checked. Counts can change and a charger may be out of order, so live availability is coming next.

Fuel prices

Fuel prices come from the UK government's Fuel Finder scheme, which forecourts report to. Each price shows how long ago it was reported.

Routes and place search

Routes and the search for towns, postcodes and addresses are by Mapbox. Each services is matched to its place on Google Maps, so directions open in the right spot.

Maps

The coastline and roads on the app's maps come from Natural Earth, which is in the public domain.

Logos and photos

Brand logos and photos of service areas come from Wikimedia Commons, and photos also come from Terns drivers. Each photo names its photographer and licence in the app.

Reviews and corrections

Ratings, reviews, photos and fixes come from Terns drivers. If something looks wrong, tell us in the app or email support@terns.uk.
