Offline maps on Meshtastic

Some conscious thought will have to go into avoiding the bias of using urban areas for map examples. 4 of 5 OpenStreetMap basemap layers, which are the main source other apps draw from, are almost completely useless when there are no roads to display. For example, this is the 4km surrounding my home… completely blank…

If the off-the-beaten-path use-cases (hiking, search and rescue, etc.) are to get any value from the maps, the only OSM layer that’s useful in likely locations is the Cycle Map, which at least shows topographical lines.

This is the Cycle Map for roughly the same area as above. Transport, OPNVKarte, and Humanitarian are also blank here.
