Currently, Topo maps are available for Explore members on the FATMAP App for Switzerland (coming soon for more countries and to the web platform). They can be accessed in the Terrain Tools, see screenshots below.
As you can see, when the Topo maps layer is active, the map retains all functionality - you can still view all the adventures on the map and navigate as normal.
In order to keep download size, speed and costs consistent with what we now offer, Topo Layers are currently not available in Offline mode.
Your feedback is important to us! If offline functionality would be valuable for you, please let us know by emailing us at email@example.com
