You might be right - but on a technical front, it's no more burdensome to show all of [unsealed, unpaved, gravel, dirt] as a dashed line rather than just, say, unpaved. Steve Are you rendering that with Mapnik ? I planned to do something similar to show the Guardians of the Slippery Map how cool it was but found it non trivial and have not had time to get back to it.

In particular, the mapnik rendered slippery map on the OSM website FYI, the map style I'm working on for cycle touring does make this distinction: http://emscycletours.site44.com/map2.html#egrt Also a quick stat for you. 165,000 highways in Australia have a surface tag. 718,000 don't. They show little interest I must admit but will show even less if we point to a whole range of surface= tags that need that treatment. So might be better agreeing on one term rather than being very specific and saying 'dirt', 'gravel' etc. As I have mentioned before, this is a road safety issue as much as a presentation one.

I really like multi-level tags. natural=water water=lake surface=unpaved unpaved=gravel surface=paved paved=asphalt It makes it easy for people two write simple parsers without enumerating the options, but people who are want to parse the details to do so. There are a number of instances when OSM uses this type of multi-level tagging scheme, but it lacks any form of consistency.

Yeah - I try to specify it wherever possible though, outside cities.

There are a lot of people who still think the best thing to do is make up new tags on the fly and to encourage others to do the same.

Re: [talk-au] surface=unsealed in 4wd/dirt road tagging
Ian, at the time, someone, I am not sure who, preferred 'unsealed' arguing that unpaved did not mean the same thing. Roads can be sealed in ways that do not really mean paved. Personally, I did not care, being more interested in getting it documented so we all used the same tag. However, now, looking at the numbers, I have to say that 'unpaved' would be seriously preferable ! So, my vote, change it.
