You can now customize your map sources on the main map of gaiagps.com, and these changes sync seamlessly with the app.
In the past, using non-default map sources on gaiagps.com required adding them from within the Gaia GPS app, then syncing the changes back to the website. So instead, you can now add all available layers directly on gaiagps.com.
Adding a map source on gaiagps.com/map works similarly to the Gaia GPS app. Access the Add Map Sources option from the Layers menu, then choose a source from within one of the available categories, and add/remove with the + and – symbols.
For detailed instructions about adding map sources on gaiagps.com, follow the step-by-step instructions with pictures in this Help Center article.
