Where the data comes from
| OpenStreetMap | Course outlines, greens and hole lines, and pars in some courses. © OpenStreetMap contributors, available under the Open Database License 1.0. |
|---|---|
| Yard Buddy | Green centers for some courses, under the ODbL 1.0. Yard Buddy is itself built from OpenStreetMap. Yard Buddy license notice. |
| USDA NAIP | Some green centers come from our own model run on USDA NAIP aerial photos, which are in the public domain. A photo can be a few years old, so a green may have moved since. |
The satellite map in the app is Apple Maps, with Apple's own credits shown on the map. It is not part of the course data.
Download the course data
- Course list (catalog.json), naming every course file with its version and SHA-256. Each course file sits beside it.
- Course list, version 2, which also lists green sets for courses without hole numbers.
- License notice for the files.
The course lists and files are made available under the Open Database License 1.0. Individual contents are under the Database Contents License 1.0. You may copy, share and adapt the data if you credit OpenStreetMap contributors and share what you build from it under the same license. The signature file only tells the app which files to trust. It does not limit what you may do with the data.
