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).
LIMA supports current scientific polar research, encourages new projects, and helps the general public visualize Antarctica and changes happening in this southernmost environment.
Data Identification Fields:
QualityThe 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.
Use ConstraintsThere is no guarantee of warranty concerning the accuracy of these data. Users should be aware that temporal changes may have occurred since the data was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of their limitations. Acknowledgement of the originating agencies would be appreciated in products derived from these data. Any user who modifies the data set is obligated to describe the types of modifications they perform. User specifically agrees not to misrepresent the data set, nor to imply that changes made were approved or endorsed by the U.S. Geological Survey.
