While scientists and engineers at the U.S. Geological Survey’s EROS Data Center, just north of Sioux Falls, South Dakota , collect satellite imagery to document Earth’s natural disasters, they sometimes enjoy the images for their aesthetic beauty as well. The scientists select about 40 of these images for a special exhibit, called “Earth as Art,” at the Library of Congress. The exhibit is now in its third incarnation, and the latest prints just recently arrived in Washington, D.C. to begin their one-year stint on display. All of the Earth as Art images are available at the link above, and can be downloaded for personal or commercial use. According to Dirk Lammers from the Assicoated Press, some of the images have made it into German coffee table books and neckties.
