Filtering Overpass-API by country

Question

Does anyone know how to perform a overpass-api request like this?

"Show me all banks in Germany"?

I could just show all 'amenity = bank' in a specific bounding-box. But Germany (or most of all countries) doesn't fit very well in such a bbox.

Is there any way to do this? Have you an example? Server performance or runtime is secondary since we could host a own server or something like that :)

Answer 1

Using Overpass turbo, the syntax is:

area["name"="Nordrhein-Westfalen"]->.boundaryarea;
(
nwr(area.boundaryarea)[amenity=bank];
);
out meta;

nwr is a short for node-way-relation

Answer 2

The Quick OSM plugin for QGIS generates the following working Overpass query:

<osm-script output="xml" timeout="200"> 
 <id-query {{nominatimArea:Austria}} into="area"/> 
 <union>
      <query type="node">
           <has-kv k="amenity" v="bank"/> 
           <area-query from="area"/>
      </query>
      <query type="way">
           <has-kv k="amenity" v="bank"/> 
           <area-query from="area"/>
      </query>
      <query type="relation">
           <has-kv k="amenity" v="bank"/> 
           <area-query from="area"/>
      </query>
 </union>
 <union>
      <item />
      <recurse type="down"/>
 </union>
 <print mode="body" />
</osm-script>
