QuickOSM returns no result

Question

I am trying to download the polygons for the Umweltzone Heidelberg from OpenStreetMap using QuickOSM in QGIS. I queried by name as shown in the screenshot:

The corresponding OSM script looks like this:

<osm-script output="xml" timeout="25"> 
     <id-query {{geocodeArea:Germany}} into="area"/> 
     <union>
          <query type="node">
               <has-kv k="name" v="Umweltzone Heidelberg"/> 
               <area-query from="area"/>
          </query>
          <query type="way">
               <has-kv k="name" v="Umweltzone Heidelberg"/> 
               <area-query from="area"/>
          </query>
          <query type="relation">
               <has-kv k="name" v="Umweltzone Heidelberg"/> 
               <area-query from="area"/>
          </query>
     </union>
     <union>
          <item />
          <recurse type="down"/>
     </union>
     <print mode="body" />
</osm-script>

The query runs successful however no result is returned.

I also tried to download by relation id running this query:

rel(2676846); >; out meta;

This downloads two points - nothing more.

How can I download the polygons for the Umweltzone Heidelberg?

Answer 1

I guess your query area Germany does not exist with that name. Using Deutschland and disabeling the timeout returns the data.

I zoomed around Heidelberg and ran the query successfully and much quicker, querying the extent of the map canvas.

Answer 2

If you don't want to zoom before around Heidelberg and if you are pretty sure that only one object is called Umweltzone Heidelberg, you can set a quick query like this :

• key name
• value Umweltzone Heidelberg
• in : empty value.

This will create only an attribute query, not a geographic query. This kind of query is very quick.

<osm-script output="xml" timeout="25">
    <union>
        <query type="relation">
            <has-kv k="name" v="Umweltzone Heidelberg"/>
        </query>
    </union>
    <union>
        <item/>
        <recurse type="down"/>
    </union>
    <print mode="body"/>
</osm-script>
