There’s a popular web site called “Where’s Tim?” which follows the places a guy named Tim Hibbard is going: live in Google Earth or Google Maps. Tim is using a phone with GPS. As he moves he leaves a trail of where he’s been, or you can load a history for a given day. Some people wouldn’t like this kind of scrutiny. But, Tim works for a company called EnGraph which sells GPS tracking software. So, it is good marketing for his employer.
Tim also has had a simple “Fly To with Google Earth” which shows a placemark of his current location on the satellite photos in GE. I sent him some E-mails and suggested he try using a GE network link to follow him interactively, and I suggested he allow history paths to be shown in Google Earth as well. He has already implemented both.
Here is the Where’s Tim GE network link (he comments here) which updates once every 15 seconds. If you click on the Placemark you get his location and current speed (if he is moving).
If you are on the Where’s Tim main page, you will see a place to enter a date to “Get History” on the lower left. After you enter a date and hit “Go” you get an option below the date to “View History in Google Earth”. This will load his track for a given date. Here’s today’s path for example. By the way, Tim is kind of easy to find because he lives and works in Lawrence, Kansas – the default location Google Earth starts with. via GoogleMapsMania which also links to another person being tracked with Google Maps.
