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. On Tue, Feb 7, 2017 at 2:41 PM, Gerd Petermann < gpetermann_muenchen@hotmail.com> wrote:
Hi all,
I noticed that the wiki http://wiki.openstreetmap.org/wiki/Key:surface mentions a few more surface values which are considered unpaved compared to the default style. The current rule in the lines file contains this highway=* & (surface=cobblestone | surface=compacted | surface=dirt | surface=earth | surface=grass | surface=grass_paver | surface=gravel | surface=grit | surface=ground | surface=mud | surface=pebblestone | surface=sand | surface=unpaved | mtb:scale=* | tracktype ~ 'grade[2-6]' | smoothness ~ '.*(bad|horrible|impassable)' | sac_scale ~ '.*(mountain|alpine)_hiking' | sport=via_ferrata) { add mkgmap:unpaved=1 }
The wiki also llists these as unpaved: gravel_turf , fine_gravel, ice, salt, snow, woodchips
I think the rule should at least contain gravel_turf, snow, and woodchips. My understanding is that fine_gravel, ice , and salt are rather smooth surfaces.
Comments?
