The Landsat Image Mosaic of Antarctica

"The Landsat Image Mosaic of Antarctica (LIMA) is the first true-color, high-spatial-resolution image of the seventh continent. It is constructed from nearly 1100 individually selected Landsat-7 ETM+ scenes. Each image was orthorectified and adjusted for geometric, sensor and illumination variations to a standardized, almost seamless surface reflectance product. Mosaicing to avoid clouds produced a high quality, nearly cloud-free benchmark data set of Antarctica for the International Polar Year from images collected primarily during 1999–2003...."

I like movies, one of my favorite is “The Thing” in the sci-fi/horror category. The story plays on an Antarctic research station. The man can feel on this place the weakness, it is impossible to get help. If I could choose between ice and desert, like extreme places on the earth, I would like to travel to Antarctica. Darkness and nothing (wintertime)…. It is peaceful!
