Interesting. I don't disagree with this, but I though I'd put in my two cents - don't forget about verifiability. I think it is desirable to be able to tag a particular way (by considering the characteristics of that way only) without knowledge of the entire local road-grid. I can only presume that this is why little examples like "lines on the street" are given. If this doesn't apply in Australia, I think other more appropriate *concrete* examples would be helpful, especially for new mappers. > > We might not be able to use exactly the same routing settings as in > > Europe, but I'm pretty certain they are never going to work as-is > > anyway, simply because things are different over here. > > this I don't understand.

Please, don't tag for the router! Tag what's on the ground (e.g. go ahead and call a street residential if it's a residential street, etc. - these should be defined according to the characteristics of the ways as they are on the ground), then leave the routing settings for the router (e.g. in Australia, tell your router whether or not you prefer residential streets to unclassified streets, etc.). What's important when deciding how to tag ways is that they are verifiable, and accurately describe the physical reality. If you do that, routing (and rendering) will take care of itself. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
