THAT is the key point here Width tags and other flags - against accurate mapping of details > Can I check?

Camp one is - single way with lanes=4 + bridge section Camp two would prefer all elements mapped in which case the bridge WOULD be a separate element. At the moment we have a hoch podge somewhere in between, with people splitting ways and adding detail and others putting extra tags that identify the situation without providing the detail. > Also I thought street was a "band" word & anybody quoting it was given a > slap on the wrist & told to go & stand on the naughty step :-) Lots of streets around here, but the only things banned would be vehicles on the pedestrian only ones ;) Anyway Top down view - single way with lots of tags such as 'bridge'. Bottom up view - every detail mapped and 'linked' in some way but each with it's own structural element. -- 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
