The combination of Google Maps, GPS, WiFi and cell tower location data can track you down wherever you are. You can also track your spouse, children and friends. This is what Google’s latest service “Google Latitude” brings to Mobile users. The service is compatible with most color BlackBerries, Windows Mobile 5.0, phones powered by Google Android mobile software, Symbian S60 Device and very soon the iPhone and the iPod touch.

How does it work?

Download the latest version of Google Map on your mobile device. After this you send out email invites to your friends or whoever you want to track to join. When the invitations are accepted, if the invitees have Google account with a profile picture, you’d see them on the map. You can determine the distance and the direction to get to their locations. The service is not a totally service, but an extension of Google Maps. You can even see the locations of your friends through iGoogle on your PC.

What if you don’t want to be stalked?

Google respects the need for privacy, so there are many ways to use this service. You have the option to select who among your friends and family members can track you. Thus you have the option to display to selected people or hide your location from all by shutting toggling off the service.

Steve Lee, product manager for Google Latitude describes the capability of the new service: “For example, a girlfriend could see if her boyfriend has arrived at the restaurant and, if not, how far away he is.”

iPhone and iPod touch users have to wait for some time for this new Google service. We will know soon whether this service is a good or a bad stalking tool.
