Re: [talk-au] dirt roads
Unfortunately i can't find my original comments on tracks and 4wd_only, but I'll concede that highway=track doesn't necessarily mean 4wd_only=yes. I don't like 4wd_only=no because many tracks that may be used by 2wds can rapidly deteriorate to a 4wd track and, as previously mentioned, weather can change everything. I know forestry roads that are definitely classed as touristy roads but, add a bit of rain and keep the grader away for a while and that road is pretty rough in a 4wd. No tag leaves the onus on the user to use his/her own discretion. There's also the problem of what type of 2wd. Yeah i know I'm picking at this but I've heard the comments from the knuckleheads. A Falcon is a 2wd - as is a Kia Carnival and a Jag and a Ferrari. Does 2wd_only mean all those? No tag = up to the driver to work it out.

Seems to me two issues not completely clear - 1. Nathan sees all cases of highway=track implying 4x4 required. I don't really agree, the dynamic range in this space is just too tight, we need to use 'track' on roads that are both 4x4 and not 4x4. Thats what 4x4_only tag is for. Whats the feeling here folks ? 2. Ian likes the idea that tracks or unsealed roads can be marked 4x4_only=no if someone has done a survey and decided that's appropriate. Particularly in places where there may be some assumption that the tracks are often pretty tough. I am not completely convinced, see two problems, it does, to some extent, change the idea that default is 'no'. Secondly, importantly, tracks change over time and people opinions on what is and is not a 4x4 track vary. Saying you will be OK in a conventional car is a lot stronger statement than you might/will need a 4x4. Comments please ? At present, mainstream rendering? emphasizes the purpose of a road. Trouble is that (possibly uninformed) people look at the maps and assume a thick prominent line means a well maintained, probably sealed road. I think there is some agreement that a means of showing the 4x4-ness of a track on the mainstream (ie mapnik) maps is desirable and possibly a safety issue. The best way to show this might be to append 4x4 to the name of tracks where 4x4_only is set to yes or recommended (Matt).? Similarly, showing sealed/unsealed may also be a good idea. I note that if you look at the slippery map on osm.org, click Map Key at a zoomed in level there is a key for unsealed road, a thick grey dashed line. I spent an hour looking for an example of that on Australian and overseas maps but found none. But thats what we want ??? If we are to have even the slightest chance of getting changes in this space, it will be because we all agree and play the safety card ! I will clarify lanes=1 where two cars cannot pass at 'normal' speed (Paul, John). And no lanes= tag for default situation. I will also suggest that survey is probably required for tracks, sat or aerial sources risk missing things like water crossing or gates that completely change the nature of the whole road. A safety issue again. David -- next part -- An HTML attachment was scrubbed...

[talk-au] surface tag
Hi People Sorry if this has already been stated, I have not mapped since the licence change and I am only reading some emails. I my humble opinion, surface=unpaved should not be used. surface=paved should only be used is the surface is literally paved with brick, bluestone, cobblestone, whatever. surface=asphalt should be used for asphalt or bitumen. surface=gravel should be used for gravel roads. surface=dirt should be used if there is no surface covering, the track has been literally made out of whatever the ground is made out of. Think fire breaks. surface=sand where there is no surface covering, but the ground is sand or very sandy. surface=concrete for concrete bike or walking tracks. surface=wood for wooden walkways, jetty's and so forth. I even have a faint memory of using surface=grass, where the track was very overgrown, but too many tags might not be so good for rendering machines. I do not think I ever used it, but I think there is a smoothness tag which might be worth some research if you are worried about a track falling between 4x4_only=[recommended; yes;no]. The 4x4_only tag might be better left to legal definitions set by rangers. As well as a speed_limit tag, thought should be given to a speed_avg tag. Some roads might have a legal speed limit of 100 kmh, but you can be lucky to get out of second gear because of the rough road surface, or even heavily used roads that are normally very crowded, and the average speed is actually not very fast. The speed_avg tag would be handy for routing engines. My 2 cents worth. Andrew.

Unmade roads These are typically forestry and remote tracks, while they may have been cut initially by a bulldozer they are not regularly maintained and, importantly, are not domed and don't have good run off gutters on the side.

Re: [talk-au] Dirt Roads
Mapnik 2 will allow tagging of 4wd_only=recommended and 4wd_only=yes. An example of 4wd_only=yes here: http://map.4x4falcon.com/?zoom=14lat=-20.73023lon=116.99701layers=B0F The 4wd_only=recommended is similar but shows 4WD Recommended.

I'm happy for you to use that link as a reference. I'll refrain from commenting on the remainder of that para.
