Find ways in location with a key greater than X

Question

In a city-sized area, I'm looking for buildings that have more levels than 12. I know that those are tagged with building:levels (untagged buildings are not interesting in this case). I have been trying to get them from Overpass Turbo, but AFAIK there's no way to say "find value > 12", and matching way["building:levels"~"^[234][0-9]$"]; times out (and only matches 20-49 anyway).

Is this the right tool? If so, how should I do this? If not - should I perhaps get an OSM extract and process it as XML with some other tool?

Answer 1

I have found a way to hack around this in Overpass Turbo. Apparently, it's not possible to directly compare numbers, but it's possible to use regex - match "100-499" or match "20-99" or match "13-19". It's still not foolproof (fortunately, this key is unitless), but works with buildings up to 499 floors:

[out:json][timeout:25];
// gather results
(
  // 100-499
  way["building:levels"~"^[1234][0-9]{2}$"]({{bbox}});
  // 20-99
  way["building:levels"~"^[23456789][0-9]$"]({{bbox}});
  // 13-19
  way["building:levels"~"^1[3-9]$"]({{bbox}});
);
// print results
out body;
>;
out skel qt;

(Yes, I'm aware that with regex, I now have two problems ;))
