Attribution & data sources
Airfree Maps runs on our own internal map graphs built from open and licensed data — never a third-party map provider. This page records exactly what we use and the attribution you must display.
The attribution you must show
Wherever you display Airfree Maps imagery, tiles or geocoded results, you must show the data attribution:
© OpenStreetMap contributors
Our interactive maps show this automatically. If you build your own interface with our tiles or data, you are responsible for displaying it — see licensing for your obligations under the Open Database License (ODbL), including share-alike.
