I would like to extract airports' boundaries from OpenStreetMap. Therefore, to extract data from a given country, for instance France I do:

area["name"="France"]->.boundaryarea;
(
node(area.boundaryarea)["aeroway"="aerodrome"];
way(area.boundaryarea)["aeroway"="aerodrome"];>;
relation(area.boundaryarea)["aeroway"="aerodrome"];>>;
);
out meta;

However, I would like to search for such data for the whole world, i.e. without limiting the area. Is there a node representing the world or do I have to loop such queries country by country ?

Basically, you can just drop the area parts of your query to get what you want:

 (
 node["aeroway"="aerodrome"];
 way["aeroway"="aerodrome"];>;
 relation["aeroway"="aerodrome"];>>;);
 out meta;

but your query might get cancelled due to server load.

Alternatively, you can query by bbox fo parts of the world.

    Union is missing in the answer, otherwise nodes, ways and relations will never be in the query result. It should read: (node["aeroway"="aerodrome"]; way["aeroway"="aerodrome"];>; relation["aeroway"="aerodrome"];>>;);out meta;. Also, [maxsize: ] and [timeout: ] are most likely needed as well. In any case, I would start with smaller bboxes rather than a global query.

  • And, of course, you could dl the data yourself and work w/ that (it's huge, but somewhat useful to have locally).
