Just saw a post on Edugadget about a cool use of Google Maps to create walking tours about places. An example is Jon Udell's screencast, and a recipe for doing this is available on Engadget. This is really cool. You need to have to have the right gear, such as a GPS device and some scripting ability, and I'm not sure how difficult that will be. It would be great if teachers could create tours to guide students in field trips, if websites could give visual directions to find places, if tourist websites could show me how to get from one place to another.
Another "yay!" from Google!
