ground truth

OSM has a maze of footpaths in that area and several unconnected sections of piste.

Tell me about it. I've just set about properly checking/adding the tracks of my M4 routes to OSM, starting on Saghro. I've seen these unconnected scraps all over and which really ruin a map as, of course, they don't make sense unless you believe in magic carpets.
I think many are mislabeled game trails which, as we know, come and go.
The culprit on Saghro seems to be an Austrian OSM-er who's been merrily adding them for years (as well as real data, tbh), using in places some sort of LIDAR-aided vision to discern 'paths' where often nothing is visible on aerial. Often his unconnected paths get an 'Issue' warning/label, rightly saying path must be part of a network. Worst still, looking in the High Atlas, he's not the only one adding what they think is a 45-m path miles from anywhere.
And yet there are loads of actual paths/tracks visible on aerial in Saghro that can't have cropped up overnight that he's ignored.
Hopefully he's had his fun in Morocco and found another hobby.
