GPS based photo tagging might be the answer to our photo organization mess - quick poll, how many of you think you have the perfect workflow? Think about it, next time you download pictures, the software automagically knows where they were taken .. sync up with your datebook, and you have images tagged with "Vacation in Bahamas" or "Happy Hour at place x". While some people including our own folks at engadget have added GPS information to photos, newer cameras like the Ricoh Caplio G3 comes with an optional GPS receiver.

Free software like StuffWare Photo Studio, World Wide Media Exchange Utilities and OziPhotoTool can all update photo tags with track logs from popular GPS receivers.

Once GPS information has been tagged to digital photos, commercial software like GPS Photo-Link ($229) and TopoFusion ($40) can generate maps using topographic or aerial data. With a photo record superimposed on a world map, you can quickly and easily relive a travel journey, see the distribution of photo subjects or visualize a historical record.
