To celebrate President’s Day, and as part of their push to promote Google Earth as an educational tool, Google has launched a new addition to their Google Earth showcase. An interactive timeline mapping the birthplaces of all 44 presidents.
The application runs in the Google Earth plug in, and is implemented as a series of tours which fly between birth places in the order each president was in office.
Also included are overlays showing which states were part of the union at the time that particular president was in office.
