Landsat Image Mosaic of Antarctica (LIMA)

Version Not provided eng
  • Abstract
    A team of scientists from the U.S. Geological Survey, the British Antarctic Survey, and the National Aeronautics and Space Administration, with funding from the National Science Foundation, created LIMA in support of the International Polar Year (IPY; 2007–08).
  • Purpose
    LIMA supports current scientific polar research, encourages new projects, and helps the general public visualize Antarctica and changes happening in this southernmost environment.

    Quality
    The team created LIMA from over 1,000 Antarctica scenes taken by the Enhanced Thematic Mapper Plus (ETM+) sensor since Landsat 7 launched in 1999. The selection process began with the team searching through 8,000 scenes with 0 to 10 percent cloud cover. As much as possible, scientists chose adjacent scenes from a single Landsat pass over Antarctica because of the consistent sun angles and weather conditions. For areas without a cloud-free scene, over 15,000 more scenes were assessed for minimum cloudiness and for cloud-free portions of the scenes. Finally, areas with overlapping scenes were studied to select the best quality data available. For areas without any clear images, scientists used the least cloudy image.
