standard geotagging logo?

Bruce McKenzie of bioneural.net proposes a standard icon to indicate geotagged information, postings etc.

In A web standard icon for geotagging, he writes

co-ordinates are typically encoded within metadata (or microformat) tags making them visible to machines but hidden from people. We have de facto web standard icons to help identify feeds, OPML, and sharing—so why not for geotagged content?

Sounds good to me.
