Tour of California and a Google Maps Mashup

So it looks like the Amgen Tour of California had a super cool “mash up” of google maps, and some GPS stuff. Super Cool. kind of interesting none the less:

“The tour’s top five cyclists will be tagged with the devices during each of the race’s stages. Additionally, one rider from Team CSC and one rider from T-Mobile’s cycling team will carry a location device every day. The system uses a complicated home-brew combination of GPS data, general packet radio service signals, HTTP streaming and SMS messaging to send data to and from the network of about 20 GPS satellites.”
