Want a cool sightseeing tour on a hot day? How about Antarctica? Now you can see it without ever leaving the comfort of your chair.
The University of Minnesota's Polar Geospatial Center has teamed up with Google maps so anyone (with a computer) can take a virtual tour of polar explorer Ernest Shackleton's hut or Robert Falcon Scott's supply hut.
The Geospatial Center (www.pgc.umn.edu) uses state-of-the-art techniques to help researchers solve problems on the top and bottom of the world -- "the least mapped places on Earth." For this project, research fellow Brad Herried took more than a dozen images of the historical sites, then Google used them to expand its 360-degree take on Antarctica. (Note the dead penguin in Scott's hut).
