Hospitals in a country

Hospitals are mostly mapped as areas covering the site, sometimes as multipolygon relations. nwr with out center turns them all into one point each.

The query

[out:json][timeout:60];
area["ISO3166-1"="IE"][admin_level=2]->.ie;
nwr["amenity"="hospital"](area.ie);
out center;

Run it

Live result from overpass.ch, cached for up to 12 hours. Map data © OpenStreetMap contributors (ODbL).

How it works

1. Hospitals are rarely single nodes; most results are ways and relations.
2. Use out geom; instead of out center; to get the site outlines.

Variations

• Emergency departments: add ["emergency"="yes"].
• Clinics and doctors are amenity=clinic and amenity=doctors.

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.
