IMHO there is no "landuse" inside another landuse (at least for the "true" landuses which are the landuses by man. If we use landuse=forest to indicate trees they might also be stacked). A rooftop park IMHO is not about landuse but is a part of the building. Landuse is about the use of _land_ (and therefore is at ground level). You should not cut a hole in the outer polygon because if the garden on top of the building influences the landuse it will influence it for the whole plot. cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
