如何获得所有OSM方式和标记便利设施的节点，以及使用Overpass API的方式节点？

Question

I'm trying to get all the ways and nodes with an 'amenity' key, which works okay with a union, but I also need the nodes that make up a way, and the recurse tag isn't working as expected:

<osm-script>
<union>
<query type="way">
  <has-kv k="amenity" regv="."/>
  <bbox-query s="%s" w="%s" n="%s" e="%s"/>
</query>

<query type="node">
  <has-kv k="amenity" regv="."/>
  <bbox-query s="%s" w="%s" n="%s" e="%s"/>
</query>
</union>
<recurse type="way-node" />
<print/></osm-script>

The %s are placeholders. Thanks!

Answer 1

With your code, the results of the way query are replaced by the results of the recursion. Therefore, you should have the (usually untagged) nodes of the amenity ways in your output, but not the ways themselves.

Putting these in a union together, however, means that both the ways and their node end up in your output:

<osm-script>
  <union>
    <query type="node">
      <has-kv k="amenity"/>
      <bbox-query {{bbox}}/>
    </query>
    <query type="way">
      <has-kv k="amenity"/>
      <bbox-query {{bbox}}/>
    </query>
    <recurse type="way-node" />   
  </union>
  <print/>
</osm-script>

The {{bbox}} are placeholders for multiple parameters as in your example. If you want to test the modified query yourself, try this Overpass Turbo link .

(Also note that you can omit the catch-all regv parameters.)
