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. Gerd ligfietser wrote

The problem is that it works too well. Paved roads with some potholes which are marked as bad are avoided.

On the forum there is support for skipping smoothness=bad from the list of unpaved options, but to add a road_speed penalty instead.

I think of adding this rule after the unpaved rules

highway=* & mkgmap:unpaved=0 & smoothness ~ '.*(bad|horrible|impassable)' { add mkgmap:road-speed = '-2' }

I did not try if the rule itself works. If it catches "bad", "very_bad", and all worser values I think it is good as it is.

Hi list,

On the Garmin OSM forum there is a discussion started whether we should consider smoothness=bad as unpaved. In the default rules it is treated as unpaved. What do you think?

Should we adapt the rules and skip 'bad' from the unpaved list?

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 ________________________________ Van: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> namens lig fietser <ligfietser@hotmail.com> Verzonden: maandag 6 februari 2017 01:40:46 Aan: mkgmap-dev@lists.mkgmap.org.uk Onderwerp: Re: [mkgmap-dev] Is smoothness=bad unpaved?

Thanks Andrzej, I got a bit confused there. The issue was caused by the generic new typ file that marked the track line type as 'unpaved road' . Should be better if I use 'track' or add another label 'paved' to it. Van: Andrzej Popowski Verstuurd: dinsdag 7 februari 00:46 Onderwerp: Re: [mkgmap-dev] Is smoothness=bad unpaved?

Rule is OK. If you negate conjunction (by use of "unless"), then you should use disjunction of negations: highway is unpaved when there is *no* surface and *no* tracktype and ... equivalent: highway is unpaved unless there is surface or tracktype or ... -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
