Rather than highjack Adam's thread any longer, tiem to set-up my own to try & work out what I'm doing wrong?
Thanks everybody for input & suggestions! I've noticed quite a few buildings tagged as "building:levels=0", which is obviously wrong as it means they don't even have a ground floor! (& I know that I'm responsible for some of them as I was confused about them as well, probably over levels v layers? So, when I do an OT search it brings back results eg https://overpass-turbo.eu/s/19Pt, which apparently shows 13 buildings in & around Perth with 0 levels. I've then tried to set up a Roulette challenge to check these, but can't get it to work? https://maproulette.org/admin/project/3119/challenge/20253 but you may not be able to see it as it says "Not Discoverable", despite "Discoverable" being set to Yes? Data source is: //State area[admin_level=4]["name"="Western Australia"][boundary=administrative]->.a; way(area.a) [building] ["building=yes"] ["levels=0"]; out ids geom ; but that (usually) runs through "Task Building" then brings up "No Tasks", which, to me, means it can't find any buildings with level=0 in WA? I'm guessing I've specified the search parameters wrong, so any advice will be more than welcome! Thanks Graeme
