Associated Press has a video to go along with last month's story "GPS Adds Dimension to Online Photos".
Not exactly an amazing video, and with a minor error (mixing Google Earth in with photo sharing sites - perhaps confused with Picasa / Web Albums). I had problems with the video in Mac Firefox but it played fine in Mac Safari.
The story itself is fairly good
Typically, a photographer carries a standard GPS device that records location and altitude data every few seconds. That information then is matched with the time stamp on photos, using software like ... RoboGEO.
Devices that already support geotagging include some GPS-enabled camera phones from Sprint Nextel Corp. ... High-end cameras from Nikon Corp. and Ricoh Co. can directly connect to GPS devices, while the upcoming PhotoFinder from ATP Electronics Inc. will write GPS information directly on a camera's memory card.
And photo-sharing services like SmugMug, Google Inc.'s Picasa and Panoramio and Yahoo Inc.'s Flickr let you manually add photos to a map. Zoom in to New York's Central Park, for instance, to find individual photos taken at Strawberry Fields and other landmarks.
Google, meanwhile, extended geotagging to its YouTube video-sharing site last summer.
(It's not clear what Sprint phones they are referring to - Sprint has a lot of GPS support, but I don't see anything about them having phones with built-in photo location coding.)
