Here is exactly where it comes from. Every course on Birdied starts life as a record in OpenStreetMap - the open map of the world, built by hundreds of thousands of volunteers. We add detail on top, and we tell you which is which.
Open Database License (ODbL) 1.0
Course base records - name, location, hole count, par and course type. Ingested from the Overpass API and refreshed as OpenStreetMap changes.
Google Maps Platform Terms of Service
Gap-filling detail only - a course website, a photo, a city name or a course type, and only where OpenStreetMap left that field empty. It never overwrites a value OpenStreetMap or a member already supplied.
CC0 1.0 (public domain dedication)
The architect who designed a course, and the year it was established - and only for a course we can match to a Wikidata golf entity beyond doubt.
Open Database License (ODbL) 1.0
The vector map tiles behind the Atlas - served by OpenFreeMap on the OpenMapTiles schema and rendered from OpenStreetMap data. OpenFreeMap asks for the credit “© OpenMapTiles Data from OpenStreetMap”, and the same ODbL licence as the course data applies to the map itself.
Public domain
Country and region boundaries - the polygons behind the Atlas borders and the country and region index pages.

Current playing conditions shown on a course page.
Some facts about a course - who designed it, the year it was established - are not in OpenStreetMap at all. We show one only when we hold a source you can open and check, and the page cites it. These are the sources that count, strongest first.
Reviews and scraped third-party listings are not citable sources here. They can point us at a fact worth checking, but nothing reaches a course page on their word alone.
Who designed a venue, and the year it was established, live on the venue record. Each of those facts is written with its source at the same time, and the sources are listed here. Signed in, every course page takes a correction.
Ratings, reviews, rounds and wishlists are written by Birdied members. They are ours and our members’, not OpenStreetMap’s, and are not redistributed under the ODbL.
A wrong hole count or a course in the wrong place is usually wrong at the source, and fixing it there fixes it for everyone - not just for Birdied.
