LIMA presents the first-ever, true-color, high-resolution view of Antarctica. Prepared from 1100 Landsat-7 images collected from 1999 to 2003, it provides scientists and non-scientists a stunning "you are there" view of the least familiar continent. Shown here are two perspectives of Byrd Glacier, one of the largest in Antarctica. The down-glacier view (above) looks northeastward and the up-glacier regional view (below) looks southward toward the South Pole which is 1050 km distant. The 15-meter resolution imagery is draped over the Radarsat Antarctic Mapping Project Digital Elevation Model Version 2.
Byrd Glacier plunges through a deep valley in the Transatlantic Mountains and onto the Ross Ice Shelf, dropping more than 4,300 feet over a distance of 112 miles. It remains a distinct ice stream all the way to the edge of the shelf, some 260 miles from the foot of the mountains to the open sea.
