I think that they generically belong to Proposed features/hazardhttp://wiki.openstreetmap.org/wiki/Proposed_features/hazard of which the article in the discussion is very eloquent regarding the wide scope or that tag. I am surprised that this proposition is 6½ years old and that taggers

2014/1/17 Gerald Weber gwebe...@gmail.com But why only roads? So why not a more generic tag to alert people about all sorts of problems? Oh please restrict that to official warnings! I can already see thousands of hazard tags of The shark attacks in Recife are alerted by official

Based on the agreed practice in Brazil, I would tag this one either as highway=unclassified or highway=track, depending on how much this is in use and what it connects (I cannot determine this from pictures alone) with surface=dirt or surface=ground. One other point I want to make. I

If you want a full justification of why a particular way was classified as it is, then I think you need a reasonably full description of a surface that would be useful for various kinds of routing. Considering what we've debated so far and also the characteristics that are used in many road

For the average mapper, I think the best solution is to have a picture of most surfaces and their corresponding smoothnesses. So a picture of excellent asphalt, a picture of good asphalt,... a picture of intermediate ground,... and a picture of horrible sand. And everything in between.
