IMHO this is valid for any kind of mapping, even where there exist clear guidelines. It's really a binary thing, either it exists and verifiable in the > field, or either it's not.

Roads don't reappear spontaneously. Paths do. Sometimes limited periods of the year. Buildings don't move spontaneously. Path certainly do. The binary cases are - visible and accessible year-round: in OSM - invisible and totally inaccessible (e.g. going through building): not in OSM I think we can all agree on that. It gets a bit more tricky in the border cases, and there I add my opinion - visible and inaccessible (e.g. due to fence): in OSM, with access=private or whatever is appropriate and mapping the barriers - sometimes visible and year-round accessible: in OSM - visible and sometimes accessible (due to fences): in OSM and lots of fun with the access tags - visible and sometimes accessible (due to vegetation): in OSM. Is there by now a seasonal tag that can be used? - invisible and year-round accessible: in OSM (*) - year-round invisible and year-round inaccessible (e.g. due to fence): not in OSM (motivation: why would it be? It's no use to anyone) (*): this is probably the most controversial one. If the consensus is that this doesn't belong in OSM, just walk it a few times and you are in the case "sometimes visible and year-round accessible". Put it in OSM as such. Just as a description of cases where it not binary. If often pass over ways that are in Atlas, but most of the time you don't see any path. I just happen to know how the way crosses the field and that's how I go. Because it is in the Atlas, I'm allowed to do so. Even when crops are growing in the field I make my way across (**). Sometimes I encounter footprints, so I'm definitely not the only one that is using it. Especially during the winter a faint path may become visible. When a group of people happened to pass a few days (or even weeks depending on the weather) beforehand, you see a more or less clear path. Should it be in OSM? For me that is yes. Even if you won't see anything most of the year. (**): unless the farmer decides again to plant those thorny things that ripped my legs open when I tried to run across them Joost, I think it would be very good to put that page online (with disclaimer that it is under discussion at the moment). You might get some heat at points where some people don't agree, but at least it will make the discussion more focused. wouter -- "Den som ikke tror på seg selv kommer ingen vei." - Thor Heyerdahl
