The Landsat Image Mosaic of Antarctica (LIMA) is a seamless and virtually cloudless mosaic created from processed Landsat 7 ETM+ scenes.

Processed Landsat Scenes (16 bit) are Level 1Gt NLAPS scenes converted to 16 bit, processed with sun-angle correction, and converted to reflectance values (Bindschadler 2008).

Each Landsat scene is processed with elevation data and sun-angle correction to ensure surface features were accurately represented. The sun's angle in Antarctica gives the appearance of a setting sun. Because of the low sun angle, as Landsat passes over Antarctica, the outer edges of the continent appear brighter than areas closer to the South Pole, so scenes have bright and dark areas. Inconsistent sun angles and shadows where corrected for these scenes. Without this process, mosaicking would produce a patchwork of scenes since each scene would have a brighter and a darker side.
