Tag filters compare text. To compare numbers, such as an elevation, use an if: filter with an expression.
The query
[out:json][timeout:60]; node["natural"="peak"](if: t["ele"] >= 4000)(45.7,6.7,46.7,8.2); out;
Run it
Live result from overpass.ch, cached for up to 12 hours. Map data © OpenStreetMap contributors (ODbL).
How it works
(if: t["ele"] >= 4000)reads theeletag and keeps peaks at or above 4000.- Values that are not numbers are treated as 0 and drop out.
- The bounding box covers the Valais and Mont Blanc massifs.
Variations
- Use
number(t["…"])when you need arithmetic, e.g.(if: number(t["building:levels"]) * 3 > 50). - Volcanoes:
node["natural"="volcano"]. - A height for every peak, also those without
ele: peaks with their height from elevation data.
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.
