GPS geotagging is supported by new digital cameras on the market as well as by a number of cameraphones including the iPhone 3G.

You can browse photos by location using the same interface used in iTunes to browse album artwork or artists.iPhoto '09 will now take that data and show the latitude, longitude, and even place names like the Eiffel Tower example shown.
