I have just started to use Python and I would like to make a query to Overpass and store the results in a geospatial format (e.g. GeoJSON) so I can programatically update the data.
As far as I know, there is a library called overpy that should be what I am looking for. After reading [its documentation](<a href="https://python-overpy.readthedocs.io/en/latest/example.html" class="">https://python-overpy.readthedocs.io/en/latest/example.html</a>) I came up with the following code:
import
overpy
API
=
overpy
.
Overpass
()
# Fetch highways within Granollers' city.
result
=
API
.
query
(
"""
area[name="Granollers"][admin_level=8];
// query part for: “highway=*”
(way["highway"](area);
relation["highway"](area);
);
// print results
out body;
"""
)
The thing is that I am not familiar at all with Python and I don't know how to store result as a GeoJSON file (Honestly, I don't even know what kind of thing result is -I tried with type(result) and I get overpy.Result as an output, which doesn't mean much to my poor knowledge). I have been reading overpy documentation but I haven't been able to figure it out.
Can anyone give me a clue with this?
