Google Latitude adds Location History and Location Alerts (beta)

Google has introduced both Google Location History and Google Location Alerts (beta) to let you do even more with Latitude. You can now enable Google Location History to store, view, and manage your past Latitude locations. You can visualize your history on Google Maps and Earth or play back a recent trip in order. Of course, you can always delete selected history or your entire location history at any time.

Google has added Location Alerts (beta). You get alerted when your Latitude friends are nearby. Alerts only trigger when:
+ You or your friend are at an unusual place, filtering out routine alert cases at home or work.
+ You or your friend are at a routine place but at an unusual time.

To enable these features, go to google.com/latitude/apps. You must first be an existing Google Latitude user; if you're not already, sign up.
