Map Data Attribution
Last updated: July 17, 2026.
© OpenStreetMap contributors. Course boundary, hole layout, and other base map data underlying CaddiDaddy's course maps is sourced in part from OpenStreetMap and available under the Open Database License (ODbL) 1.0.
1. Two layers, two licenses
CaddiDaddy's course maps combine two independent data layers, rendered together but never merged into one database:
- The OpenStreetMap layer — course name, location, boundary, hole ways, and other publicly mapped features. Licensed under ODbL 1.0, a share-alike license. This layer is never modified beyond the mapping and rendering ODbL permits.
- Our proprietary layer — tee, green, and hazard geometry we survey ourselves, GPS traces from real rounds, green contours we measure, and pin positions golfers report. This layer is ours and is built independently: it is never bootstrapped, snapped to, or "corrected toward" OpenStreetMap geometry.
Full detail on how we keep these layers separate is in our engineering clean-room data policy, which golfers, course operators, and anyone evaluating our data practices are welcome to ask about at privacy@caddidaddy.com.
2. Where attribution appears
"© OpenStreetMap contributors," linking to openstreetmap.org/copyright, appears on every map view that renders the OpenStreetMap layer, and on this page, as required by ODbL §4.3.
3. Status today
CaddiDaddy has not shipped yet — there is no live map view to attribute in production today. This page exists ahead of launch so the attribution requirement is in place before any map ever renders publicly, and will keep applying once the app is live.
4. Your course corrections
If you submit a pin report or course correction once the app is live, it becomes part of our proprietary layer, not the OpenStreetMap layer — see our Privacy Policy, Section 6.
