[mkgmap-dev] unpaved roadsFrom Gerd Petermann GPetermann_muenchen at hotmail.com on Tue Feb 7 09:19:49 GMT 2017
Yes, quite difficult. My understanding is that we don't really care about paved/unpaved here, it is more about smoothness, and probably most of the people contributing here are cyclists. I've cycled > 33.000 km through many European countries during the last years and I'd prefer to avoid surface cobblestone or concrete:plates which are "paved" but painful while I really like to travel on fine_gravel as long as it is not raining heavily. On the racing bike I'd prefer to avoid surfaces which are not smooth, but I nearly stopped cycling on them. This "raining" part is probably what paved/unpaved is about: The surface of a paved road should not change when it's raining and your vehicle will not be covered with dirt when traveling on a paved road while it is raining (at least not from dirt which was part of the surface). Do you agree on that (last sentence)?

But not suitable for racing bicycles, for them those cycleways are unpaved. I would suggest to make it unpaved for generic use and use a regular expression sytax to catch all combinations. In my OFM I solved this by using surface ~ '.*(ash|bad|clay|cob|compact|dirt|earth|erde|gr|loam|mud|peb|sand|shotter|rock|turf|unpaved).*' ________________________________ Dave wrote: But none are "paved" in the usual sense of that word. I would hate to drive on a "fine gravel" road, or an ice road, unless I was prepared for it. Even if the fine gravel were on top of a compacted substrate it would present a hazard to bicycles and motorcycles. I'm not sure I care how a "salt" road is classified - I've never seen one let alone driven on one.
