I would go for ground level if you can work it out from your survey and the aerial photography, but I wouldn't fret too much! I can't see people coming to OSM for that kind of spot-on accurate building data any time soon. I tried getting ground-level outlines as accurate as possible round my way but I've not fancied doing the same for all the buildings I've been tracing and addressing for the whole area! http://osm.org/go/euuuX@UJd-- Regards, Tom -- http://tom.acrewoods.net http://twitter.com/tom_chance
