Here I got intersection of two areas, but I want union of areas.

I find the solution here :
( area["name"="Vlaanderen"]["admin_level"="4"];
area["name"="Halle"][admin_level=8];)->.perimeter
(
  way["highway"]["name"](area.perimeter);
);
out body;

Jo,

I didn't understand completerly your suggestion. Can you elaborate a bit
more please ?

All the best

François

You could also do this:

[maxsize:4];
(
way["wikidata"="Q212429"][admin_level=3];
way["wikidata"="Q212582"][admin_level=3];
)
._>;
out geom;

No need to store it in placeholders if you only want to join.

[joost schouppe]

I got some outside help (I think on help.openstreetmap.org) but I think
this does basically what you need:

http://overpass-turbo.eu/s/rHN

(my problem was that also Halle, Germany would get returned if I didn't do
it properly)

Re: [OSM-dev] Overpass filter by area A or area B

[François Lacombe]

Hi Pierre,

Thank you for your answer
The point was to merge two area and select ways (or any object) inside the
merged perimeter.
That's why I awkwardly wrote the "way(area.area_1,area.area_2);" thing

I took random wikidata ID for the example, and I will filter objects inside
the area a lot more.
Then the result won't exceed OAPI limits.

If I can't merge areas to give only one filter at the end of the query,
then I'd better do as many queries as areas


All the best

François
