LIMA on NASA site
The Landsat Image Mosaic of Antarctica (LIMA) is the first-ever true-colour high-resolution satellite view of the Antarctic continent. Compiled by a team of researchers from NASA, the U.S. Geological Survey, the National Science Foundation and the British Antarctic Survey, it required over 1000 Landsat 7 images, nearly all of which were acquired between 1999 and 2001. NASA designs the Earth-observing satellites of the Landsat Program; the United States Geological Survey (USGS) manages the satellites, archives the imagery, and makes the data available to all interested users. The imagery is provided in true color and infrared, at no charge, for all to explore and use.
The result is a 15 metre resolution, near seamless and cloudless image mosaic of the continent. In addition to providing a stunning new visualisation of Antarctica, the dataset is also a rigorously processed surface reflectance dataset. The image mosaic is provided as both natural colour (Landsat bands 321 in RGB) and false colour (Landsat Bands 432 in RGB), and with applied contrast stretches to enhance surface details. The entire dataset is freely available to all users from the LIMA website where they can view and download the image mosaics or the component Landsat images that were used in its construction.
