And mapping wherever and however you feel like it makes for less useful maps. >>> And even if they were, this would only work if there's a median. >> >> What's a median got to do with it? > > When there's no median, the center depends on both directions. If you don't know how many lanes are in each direction, then this is a problem. But you can state how many lanes are in each direction without mapping each lane as a separate way. >> On Sun, Sep 18, 2011 at 1:40 PM, Nathan Edgars II<nerou...@gmail.com> >> wrote: >>> >>> Not to mention that the line between the lanes doesn't always go straight >>> through the intersection. >> >> Why does that matter? > > Because if the pre-intersection right lane is directly behind the > post-intersection center lane, but an angled dashed line forces you into the > post-intersection right lane, this cannot be determined without mapping this > somehow. The way is supposed to follow the angled dashed lines. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
