Overpass API - Search for Relations

hello,

I am using the Overpass API to search for relations. See my XML code:

<osm-script>
  <query type="relation">
    <has-kv k="name" regv="Uckerm"/>
  </query>
  <print/>
</osm-script>

I am executing this script at http://www.overpass-api.de/query_form.html for testing. The result delivers a lot of informations I do not need at the first step e.g. I receive all the ways

...
<member role="outer" ref="195916561" type="way"/>
<member role="outer" ref="195738108" type="way"/>
<member role="outer" ref="90844182" type="way"/>
...

I am just interested to receive all the tag elements e.g.

<tag v="county" k="de:place"/>
<tag v="12073" k="de:regionalschluessel"/>
<tag v="Uckermark" k="name"/>

Can I pass some parameter to my query to reduce the amount of data which I can receive?

Regards

Michael

You can omit the tags and print only the members, but unfortunately not vice versa.

You can try to use areas instead: Geographical relations alwas also exist as areas, and areas only carry tags, no member information.

If this is correct, we need a hint about this in the OSM wiki about http://wiki.openstreetmap.org/wiki/Overpass_API or any suitable sub page ... and on help.osm.org !

Re: Overpass API - Search for Relations

Hi!
On same overpass-api subject (don't know if this is the right place for this question, I got there searching for "overpass-api"): it looks like the openstreemap.org website "?" function (object query) is regularly showing up an error message during my mouse-directed queries. The message looks like (sorry, part of it in french!)

Do you have any idea why this could be?
