Google Earth 5.0 Beta release
2nd Feb 2009
http://earth.google.com/
Historical imagery: In previous versions of Google Earth, users could
only view only one set of imagery for a given location. Now users can
activate a time slider to see both newer and older satellite imagery
from around the globe, enabling them to observe a single location's development over
time.
Touring is a simple new way for users to create narrated tours of
imagery and content in Google Earth.
By simply pressing the "record" button, users can fly from place to
place, zoom in or out and click on content balloons, providing voiceover
narration along the way. Whether creating a tour of one's family
home or an in-depth study of environmental change, the tours are easy
to create and even easier to share.
Google Mars 3D is the latest stop on Google's virtual tour of the
galaxy. Users can travel to Mars with the click of a button and see
high resolution imagery and 3D terrain. They can fly to the top of
Olympus Mons, the tallest volcano in our solar system, read
geo-located excerpts about different locations on the planet from
A Traveler's Guide to Mars, observe where various Mars Rovers and Landers
have touched down and much more.
GPS Tracking - Previously only available in the Plus and Pro versions
of Google Earth, now all users can upload tracks from GPS devices
(including many Garmin, Magellan, and NMEA-compatible devices) to
Google Earth, making it easy to visualize and record running, hiking
and biking routes.
