If you want to keep track of where you have been you can do it with Google Latitude and Google Location History Dashboard (Beta).
There's a Beta View for Google Location History to visualize your location history. If you've already chosen to enable Location History, the new dashboard view will try to highlight g trends from your existing
location history, such as trips you've taken, places you've visited,
time spent at home vs. out, and more.You can stoe your past locations and visualize them
on Google Maps and
Earth. The dashboard showis information, such as trips,
frequently visited locations, distance traveled, and more. You can
enable Latitude Alerts to get notifications when friends are nearby.
Location
History allows alerts to only trigger when you are in an unusual place,
filtering out routine alerts.
If wondered how much time
you've
spent at work recently compared to six months ago, or where it was that
you stopped on your last road trip? Check out Location History for
some of the answers.If you're a road warrior, the dashboard can help you remember
your trips and where you stopped along the way. You can also so the total number of miles traveled.
Google Location History is opt-in only and your location
history is available privately to you and nobody else. You
may be asked to periodically re-enter your password when opening any
Location History page, even if you're signed in to your Google Account
already (just to make sure you're really you). You may always
delete any or all of your location history in the Manage History
tab or disable Location History at any time.
To try out the new
dashboard yourself, enable Google Latitude in the
background on your phone, turn on Google Location
History, and wait a few days (up to a week) to build up enough
history for the dashboard to begin showing information.
You may also want to try turning
on WiFi or GPS on your phone to improve location history accuracy.
