TUESDAY DECEMBER 10 - AERIAL PHOTOGRAPHY
Whenever I fly, I'm always
amazed by the unique view you get of the earth's surface when
looking down from thousands of feet up.
You can get such aerial views without boarding a plane, courtesy
of the U.S. Geological Survey. They have millions of aerial
photographs, many taken during the last few years from about
20,000 feet up. These photos
are used mainly by mapmakers, earth scientists, and urban planners,
among others, but they're also available on the web at the following
At this site, simply enter the name of the area you'd like to
see, and you'll get a list of images that are available. The images
may be a few years old, so you may get a view that's a little dated.
But trust me, it's very interesting
and informative and fun to try and locate your neighborhood, and,
yes, maybe even your house,
in one of these photos.
