What I am searching for is a wiki page that tells me which roads do have default values and what are these default values in which countries. Without doubt most "highway=x" have no "surface=y" in OSM because the mappers assume that certain road categories do have certain default surface values.
In Italy most roads and cycleways have no "surface" tags. If an "unclassified" road is not paved, it often has a "surface" tag. If I take the USA, "residential" roads normally have no "surface" tags, but in some areas of the USA, most "residential" roads are unpaved, in other areas practically all "residential" roads are paved. In Burkina Faso also major roads are not paved, but they also do not have a "surface" tag. @ Richard, you are describing what I thought was defined as a standard approach somewhere, but I haven't found anything. If there isn't an agreed set of defaults, then every mapper can set his own, as you doe and I do, but this means that a router has to second guess what people think is standard use in different countries. That's not terribly satisfactory. Thinking about this, what would make sense in terms of how the wiki works, i.e. reflecting the actual use in the community, is to consult the router developers what they assume the users do. BUT I don't know if we get any replies. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Sun, 22 Sep 2019 at 01:03, Richard Fairhurst <rich...@systemed.net> wrote: > Tom Pfeifer wrote: > > In the outskirts of Berlin, I have unpaved highway=residential in good > > neighbourhoods, that are muddy when wet and dusty when dry.
