It'd probably take a bit longer to convert from the OSM data to whatever format your router actually uses, but it also means you could treat roads in other landuse areas differently too. > well, tag whatever you like, I just can tell you, that the definiton > in the wiki says for residential, that there must be at least at one > side residences. The highway=residential wiki page doesn't directly say that, but may imply it. The problem is that a lot of the words used seem to be based on the British way of defining roads and that doesn't necessarily translate into non-British English very well, let alone into other languages (as seen in some of the other discussions). Most of the Highway page talks about British road classifications, and things like "(tertiary) In the UK, they tend to have dashed lines down the middle, whereas unclassified roads don't", which doesn't really help people figure out how it is supposed to apply to other countries. What exactly does "This tag is used for roads accessing or around residential areas but which are not a classified or unclassified highway" mean? If you take 'highway' to be a synonym for 'road' then suburban residential streets shouldn't be tagged like that because they are unclassified. If it's not a synonym, then how do industrial streets get tagged, because they're not highways. In addition the "Australian Tagging Guidelines" (which Liz mentioned were written a year before the residential page) explicitly disagree with the residential page. Which brings us around to one of the major questions in this argument. If the consensus (which may exist in Europe, but I'm far from certain is global) is to use one definition, but within a region there is a consensus to use a different definition, what do people want to happen? > If you don't care about this definition, do as you > like. You'll IMHO loose a datum and gain nothing. There are other ways of storing that data (e.g. landuse) and roads in Australia aren't tagged according to the highway=residential wiki page at the present time, so what exactly do we lose? 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. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
