I have a pair of old Garmin RINO 120 GPSs and a gadget to connect either of them, one at a time, to my PC, currently running F 29. For several years I could run topo map software under WINE -- unfree software from any, or almost any, of half a dozen vendors -- but never get any of them to talk to either GPS. Now there is Open Street Map, a.k.a. OSM, which I THINK runs natively under Linux.
I have studied forums and followed discussion lists (with Pan and Gmane, since most of the content is obviously unrelated to my questions). For years.
It seems that everyone else is a mapMAKER, and takes mere USE for granted. I only want to use it, and only out in the woods or the desert or the tooley weeds -- all of which, it seems, OSM does map, despite its name. I want to get maps to scale that show things of interest to me only, or I hope only -- things like good lunch rocks, and nests, and particular trees, all or nearly all off any trail.
Unlike the OSM regulars, I have no advanced skills in cartography, nor EE, nor CS. My skills and knowledge are in unrelated areas.
All this boils down to two questions. If I install OSM under Fedora, will it accept, incorporate, and display off-road and off-trail data from an old GPS, either with OSM's own data, or with things like USGS topo maps? And if it will, can an ordinary mortal learn to use it?
