layer=-1 for the underground building. You could maybe also try covered=yes > Third, a building with a courtyard, and a basement that also extends > below the basement. as we don't have elevation, the building would be drawn like all other buildings with courtyard (multipolygon relation) > Fourth a building that has been built into a cliff. At the top of the > cliff, on top of the building, are roads and sidewalks and things. simply draw the roads above the building and give them the layer tag (or the building a negative layer). Mapnik is ignoring these layers and will draw the roads in any case above the building, but for topology they are needed. > Fifth, a building on a hill, with entrances variously on the third, > second, and first floor. One of the second floor entrances leads out > onto a "green roof", which has grass planted on it and connects to the > ground, but reaches out farther than the hill would naturally. will be mapped like if the hill was flat. Simply draw entrances and ways (building=entrance on a node). If several elements overlap, order them with layers.
