Flickr, Picasa, and Geotagging
Here’s a post about some nice tools for geotagging photos and for linking Google Earth to geotagged photos. A geotagged photo has latitude and longitude coordinates of exactly where it was taken attached to it. Until we have digital cameras with built-in GPS receivers, we have to take a few extra steps to do the tagging, but the latest round of tools is making that process a bit easier.
