Document usage limitations about osmnx

[gboeing]

I'm sorry for laughing, but this guy trying to make 20 million API requests 😂

Thanks again for the links. We shall update the docs.

Note: maybe it is documented somewhere? In such case just linking it from quick start and putting it into faq would be useful.

Thanks for flagging this @matkoniecz.

Document usage limitations and policy of underlying services and mention it clearly in quick start

Good idea. We have some mention of this already but it's probably too buried. Adding it to the "getting started" guide and FAQ sounds like a good idea to me.

I can track down support requests appearing at OpenStreetMap forums.

Yes please. If you can share any more information about what they are doing wrong and what policies they are violating, we can 1) specifically highlight this in our guide and 2) implement programmatic restraints if feasible. Our goal is to always be a good neighbor.

I'm readying a patch release today (can delay slightly), but we could potentially update the docs in time to make this go live ASAP.

https://community.openstreetmap.org/t/road-types-and-speed-limits-in-nigeria/105309 is the latest one

I remember other cases, but maybe it was on IRC/Discord/elsewhere or for some other reason I failed to track them down. Or I misremember.

And it is definitely great to see OpenStreetMap data being used and being more accessible!

Though it would help everyone if people would be aware that making millions of overpass requests require having own server and that OSM editing API is for editing, not bulk downloads :)

@matkoniecz do you have any specific links to usage limits? I'd like to link to the best source to point users to an authoritative policy/reference.

[matkoniecz]

For Overpass: https://dev.overpass-api.de/overpass-doc/en/preface/commons.html

As a broad guideline to stay within safety margins, users are expected to send a maximum of about 10000 requests per day and keep their download volume below about 1 GB per day.

For Nominatim: https://operations.osmfoundation.org/policies/nominatim/

For OSM Editing API: intended use is for editing, not for read-only use

https://operations.osmfoundation.org/policies/tiles/ may be applicable, but likely not

Are there any other relevant services? (maybe you use some other Nominatim/Overpass servers? They may have own policies)

[gboeing]

Perfect. No we just use Overpass and Nominatim. (And Google Maps API, but users provide their own API key for that.)
