In my prior entry, titled EXIF - Digital Photography and GPS, I opined that we would see a revolution in digital photography once digital cameras started utilizing the available GPS related tags in the EXIF data structures. I received a couple of great responses, including one by Luke Francl where he pointed me to two great links - Mappr!, which is a dynamic application that displays Flickr photos, geocoded based upon their user added tags (e.g. A flower with the keywords Seattle, Washington would appropriately display in Seattle), and Photospace, which is an application that logs GPS data on your PC, and then in "post processing", so to speak, it sets the geographical information on the images (by correlating times. e.g. a photo taken at 1:37pm correlates with an external GPS entry saying that you were at X & Y). A very nice stopgap solution until cameras themselves integrate this functionality.
