GeoGreeting. This morning I got an email that reminded me of the service so I decided to see if it still works. Sure enough GeoGreeting still works as well as ever. It's a free service that spells out your greetings using satellite images of buildings found in the Google Maps satellite view AKA Google Earth view. Watch my short video to see GeoGreeting in action.
Applications for Education
GeoGreeting could provide you with an easy way to introduce to new users the capabilities of the satellite views of Google Maps.
Another way to use GeoGreeting would be to have students create messages then explore and research the areas around the buildings shown in the images of their greetings.
