Quickly extract GPS positioning data from an Image?

Hi --

Is there any way to quickly extract the GPS positioning data (lat, long) for a Image in Aperture -- or, equivalently, open a Google Maps page in a Web browser showing the location?

I tried:

- every menu related to Places I could find

- copying the info in the lat and long fields (can't be selected)

- copying the info from the Lift & Stamp HUD (also can't be selected).

I'm sure I'm missing something obvious.

Thanks.
