Data and attribution
Where our course maps come from, the licenses they carry, and how to get a copy.
Course maps
Where OpenStreetMap maps a whole course, its geometry (greens, fairways, bunkers, water, tees and hole lines) is © OpenStreetMap contributors. Scorecard data (par, yardage, handicap) comes via OpenGolfAPI or OpenStreetMap unless a course says otherwise. Both are available under the Open Database License (ODbL) 1.0.
Those course packs are a derivative database of that data and are available under the ODbL on request: email hello@rangebirdgolf.com. Corrections we receive are contributed back to OpenStreetMap where they meet its guidelines.
For other courses, Rangebird maps the greens, bunkers and water itself from aerial imagery and elevation data, numbered from the course's own published scorecard. Each course lists its sources under Data sources on its page.
Imagery and elevation
Aerial imagery comes from the USDA National Agriculture Imagery Program (NAIP) and NOAA Digital Coast, which are in the public domain, and from state, county and local government imagery programs, credited on each course that uses them.
Elevation and lidar come from the USGS 3D Elevation Program (public domain) and state lidar programs, credited the same way.
We never trace course features from Google, Apple, Bing or other commercial imagery.
Weather
Wind, temperature and forecasts come from Open-Meteo, available under the Creative Commons Attribution 4.0 license.
Your data
Your rounds, scores and shot positions are stored on your device and, if you sign in, in your account. They are never sent to OpenStreetMap, OpenGolfAPI or any other open dataset.
Handicap
