Returns null geometries

Hello,

From not I was only using Overpass API Python wrapper for querying nodes. I would like to use it now for querying ways and I got back only null geometries.

Here my code:

query_text = 'area(3602134786)->.a;(nwr[leisure~"^(park)$"](area.a););'
api = overpass.API()
result = api.get(query_text)

And an extract of what I got returned:

{"features": [
{"geometry": null,
"id": 51876557,
"properties": {"barrier": "fence", "leisure": "park", "name": "Parc Wilson"},
"type": "Feature"
},
{"geometry": null,
"id": 51925873,
"properties": {"barrier": "fence", "leisure": "park", "name": "Parc Napol\u00e9on", "ref:FR:FANTOIR": "576721870A"},
"type": "Feature"
},
{"geometry": null,
"id": 65283729,
"properties": {"leisure": "park", "name": "Square Robert Schuman", "source": "cadastre-dgi-fr source : Direction G\u00e9n\u00e9rale des Imp\u00f4ts - Cadastre. Mise \u00e0 jour : 2010"},
"type": "Feature"
}, 
...
], "type": "FeatureCollection"}

When I do the exact same request using Python librairy requests, I actually got non null geometries:

import requests
import json

overpass_url = "http://overpass-api.de/api/interpreter"
query_text = 'area(3602134786)->.a;(nwr[leisure~"^(park)$"](area.a););'

response = requests.get(overpass_url, 
                        params={'data': query_text})

data = response.json()

Any idea of what is going wrong?

Thanks for your help,

Pauline

I actually found the trick after having spent days in the docs and the code: You need to add the parameter verbosity="geom" when passing your request as in the following example.

query_text = 'area(3602134786)->.a;(nwr[leisure=park](area.a););'
api = overpass.API()
result = api.get(query_text, responseformat="geojson", verbosity="geom")

Hope it helps!

The conversion to geojson of relations and areas are not supported.
