Hi all, for OSM mapping purposes I like to have the possibility to add a poi for each residential (house,apartments,farm,...) building polygon that - doesn't have a addr:housenumber=* tag AND - doesn't contain a node with addr:housenumber=* AND - doesn't have a node on the outline (part of the way) with addr:housenumber=* I want to render a POI with a text like "Hnr ?" so that, when I cycle near such a building, I can decide whether I try to find out the house number. I think there is currently no way to do this with mkgmap since we don't have something like a "contains" style function. I can't remember if we even thought about this when the is_in function was added? My current work around is to use JOSM as a preprocessor but that works only for small maps. Gerd
