The universal solution for such special cases would be tagging single addresses without interpolation. This would provide information - what house numbers do actually exist? In this special case nearly every value could be possible. - where exactly is this house number? Since numbers are based on distance this could also be calculated from the given number - but what if want to know the house number of a given position? The only disadvantage of this method would be a little bit more work "on the ground" - but nothing photo mapping couldn't solve ;) _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
