This new map of Antarctica, deemed the “most geographically accurate, true-color, high-resolution views of Antarctica to date” (and 10 times more detailed than previous views, to boot), was constructed by a team of researchers from the British Antarctic Survey, NASA, USGS and the NSF. They created the images by cobbling together over a thousand images from the past three years of Landsat satellite observations.
You can see more of these stunning views on the Landsat Image Mosaic of America (LIMA) website.http://lima.usgs.gov/
