That is simply camp two ... The bridge relation would have to have a physical presence at some point! The point I am trying to make is that the two camps HAVE to co-exist. What we are looking for is a way to 'rough in' the data, and provide a macro level view of things, and then add the NECESSARY detail below that so that micro mapping can simply be added to the macro model. If that means a half way house of detailing the fine content of a way by splitting into multiple tracks, then the 'holder' for the bridge slots in to that model and can be expanded in detail later. At some point it WILL become necessary to create elements like bridges as 'paintings' with accurate graphic detail, but the higher level view only needs the single way with a bridge flag - and there is no reason that could not be provided as a tag on a single macro level view of the way? At the macro level THAT makes sense, while once one breaks a way down into it's component tracks, a tag on that view may be of more advantage to fine detail routing, while a separate bridge element makes more sense for rendering in the smaller scales? -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
