[mkgmap-dev] [Patch] unpaved roads

Thu Feb 9 09:38:46 GMT 2017

And what about combinations of surface meaning paved with tracktype? 
The wiki says "Usually ... " or "Almost always an unpaved track" for most
tracktype values.

I see quite a lot of ways with
highway=track & surface=concrete:lanes & tracktype=grade3 
in my Niedersachsen:

I think those are not unpaved, no matter how nice it is to cycle on them;-)
