The Landsat Image Mosaic of Antarctica (LIMA) is the first-ever true-color
high-resolution satellite view of the Antarctic continent enabling everyone
to see Antarctica as it appears in real life.
Faces Of Antarctica :
In support of the International Polar Year (IPY 2007-2008), LIMA brings
the coldest continent on Earth alive in greater detail than ever before
through this virtually cloudless, seamless, and high resolution satellite
view of Antarctica.
The U.S. Geological Survey (USGS), the British Antarctic Survey (BAS), and the
National Aeronautics and Space Administration (NASA), with funding from the National
Science Foundation (NSF), created LIMA from more than 1,000 Landsat ETM+ scenes.
As the first major scientific outcome of the IPY, LIMA truly fulfills
the IPY goals. LIMA is an international effort, supports current scientific
polar research, encourages new projects, and helps the general public
visualize Antarctica and changes happening to this southernmost environment.
Researchers and the general public can download LIMA and all of the component
Landsat scenes at no charge.
Pan to view the continent and zoom in to see the stunning detail of this
Natural-Color, Pan-Sharpened LIMA (bands 3, 2, 1). LIMA covers the entire
continent except from the South Pole at 90 degrees south to 82.5 degrees
south latitude, where Landsat has no coverage because of its near-polar
orbit. To provide a continental view, the image above has LIMA 3, 2,
1 overlaying the MODIS Mosaic of Antarctica (MOA).
The opening view includes McMurdo Station, the largest research base
in Antarctica. Located at the tip of Hut Point Peninsula on Ross Island,
McMurdo has been continually operated by the United States of America
since 1956. Ross Island is roughly 72 km (45 mi) across. The flat, white
areas are the Ross Ice Shelf and other sea ice off the coast of Antarctica.
Also visible are the Erebus Glacier Tongue, Koettlitz and Ferrar Glaciers,
and the Royal Society Range.
