[OSM-talk] Overpass API - Fetching countries, their capitals, and their borders

[Léo El Amri]

Hi again,

Thanks for the replies

I did several other tries this morning, but it looks like the borders
are too much to handle. Taking your answers into account, rather than
doing thousands of queries on the Overpass API, I think I'll get the
whole Planet file, then use a local tool to get the data (Anyways, in
this context, I only need this info occasionally).

Cordially,
Léo
