[mkgmap-dev] unpaved roads

Tue Feb 7 07:41:27 GMT 2017

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?

Gerd
