Aerial Imagery:
---------------------------
With the new Bing images many new relations have been created that
contain boundaries of hires images. I think it would be cool to have a
uniq tagging for such objects.
Examples without unified tagging:
 http://www.openstreetmap.org/browse/relation/1291579
 http://www.openstreetmap.org/browse/relation/396170
These are features of Bing, not of the earth. They belong with the
Bing dataset, or else another dataset which collects metadata about
imagery, but I don't think it belongs in OSM.

Also see top  of http://wiki.openstreetmap.org/wiki/Bing/Coverage

"Please use this page for recording coverage. Do not use boundary relations. Large, detailed relations can be exceptionally slow to retrieve and cause very high server load, especially when accessible via an OpenLayers slippymap client. Significant problems have already been caused by people trying to map coverage with a relation, and then posting the relation URL."
