A team of researchers from NASA, the U.S. Geological Survey, the National Science Foundation and the British Antarctic Survey unveiled today a newly completed map of Antarctica that provides a realistic look at the continent in 10 times greater detail than ever before and offers the most geographically accurate, true-color, and high-resolution views of the continent possible.

The Landsat Image Mosaic of Antarctica, a virtually cloudless satellite view of Antarctica’s frozen landscape, is expected to revolutionize Antarctic research. Researchers pieced together more than a thousand images from three years of Landsat satellite observations to construct the map. The resulting mosaic gives researchers and the public a new way to explore Antarctica for themselves through a free, easy-to-use, public-access Web portal.

The mosaic is made up of about 1,100 images from Landsat 7 captured primarily between 1999 and 2001. The collage of images contains virtually no gaps in the landscape, shows virtually no seams between images and retains scientifically meaningful information throughout the entire mosaic.
