building:levels is the number of floors above ground. number() converts it, so it can be compared.
The query
[out:json][timeout:60]; area["name"="Frankfurt am Main"]["admin_level"="6"]->.a; wr["building"](if: number(t["building:levels"]) >= 15)(area.a); out center;
Run it
Live result from overpass.ch, cached for up to 12 hours. Map data © OpenStreetMap contributors (ODbL).
How it works
number(t["building:levels"])reads the tag as a number; missing values do not pass.- Frankfurt is a district-free city (admin_level 6).
Variations
- Height in metres, where mapped:
(if: number(t["height"]) > 100).
Run it from your code
curl https://api.overpass.ch/v1/YOUR_API_KEY/interpreter \
--data-urlencode 'data@query.overpassql'
import requests
query = open("query.overpassql").read()
r = requests.post("https://api.overpass.ch/v1/YOUR_API_KEY/interpreter",
data={"data": query}, timeout=120)
r.raise_for_status()
print(r.json()["elements"][:3])
const res = await fetch("https://api.overpass.ch/v1/YOUR_API_KEY/interpreter", {
method: "POST",
body: new URLSearchParams({ data: query }),
});
if (!res.ok) throw new Error(await res.text());
console.log(await res.json());
Save the query as query.overpassql. It works the same in Overpass Turbo, QGIS and JOSM.
