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.

2. Comparison of LIMA and MODIS
The Landsat Image Mosaic of Antarctica 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.

3. Contrast Stretch
A technique called "contrast stretching" helps show the details that are still contained in LIMA's image data but are mostly hidden from our eyes due to Antarctica's reflective snow-covered surface.
