[mkgmap-dev] Is smoothness=bad unpaved?

Mon Feb 6 21:17:24 GMT 2017

Another issue that is related to the unpaved rules is posted by Peter 'Beddhist' on the forum:

https://forum.openstreetmap.org/viewtopic.php?pid=630231#p630231

highway=track & surface=paved is marked as unpaved by mkgmap.

This isssue is caused by this rule:

(highway=bridleway | highway=path | highway=track | highway=unsurfaced)
& surface!=* & tracktype!=* & smoothness!=* & sac_scale!=*
{ add mkgmap:unpaved=1 }

If my interpretation is correct, it says that all those types of highway are considered as unpaved, unless there is a surface, tracktype, smoothness AND sac_scale parameter!

I think  it should add mkgmap:unpaved=1 unless

- surface=paved,asphalt,concrete, etc* OR

- tracktype=grade1

- smoothness and sac_scale?

*) surface values that are paved are mentioned in the wiki: http://wiki.openstreetmap.org/wiki/Key:surface

Thanks Gerd!

Hi,

if I got that right the forum agreed to this, so if nobody complains I'll
change the default
style as suggested on thursday.
