Thank you for the clarification, Matheus and for the link, Dave (I am afraid
that's not what I was looking for, as it still requires to download data on osm
format).
I tried Bryce's code, which uses overpass api python wrapper
(https://github.com/mvexel/overpass-api-python-wrapper), and it just works fine!
Unfortunately, I have to admit that I don't wholly understand it (I have just
landed in Python's world). Would you be so kind to explain the following?:
- Can I add the query in more than a single line? (the provided one is quite
simple and still it is long) If so, how? (from what I am seeing Python is very
strict dealing with new lines)
- what's going on after the result? I understand there's where the magic of
creating a gjson file happens, but can't understand much about it.
Regards and thank you again to everyone!
