I see your point, and tentatively agree with it, much as I hate to say it, because it will totally screw up the current interpretation of interpolation, whereas my method will only be misinterpreted by doubling the number of valid addresses. Still as I said, it makes sense, and the weakness you pointed out in my approach is valid. -- Randy _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
