If you apply widths to the nodes, I guess, yeah, it would be possible for a renderer etc. to interpret these as requiring linear interpolation. But approximation with trapezoids or whatever is a bit fudgy....e.g. what if you *do* want to represent an instantaneous change in width? My point is that this general suggestion seems to be a way to *map areas*, by *tagging ways*. Is this actually better than to *map areas* by *tagging areas*? If so, how? _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
