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

[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)

> 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

>> Hi all,
>>
>> I wonder how to filter objects in several areas in Overpass API.
>>
>> I assume this query:
>> area["wikidata"="Q212429"][admin_level=3]->.area_1;
>> area["wikidata"="Q212582"][admin_level=3]->.area_2;
>>
>> way(area.area_1,area.area_2);
>> out geom;
>>
>> would give all ways contained in area_1 and area_2 as results.
>>
>> Is this possible ?
>>
>> All the best
