New Antarctic map will contain 1,100 hi-res images
Fourresearch agencies are getting ready to launch ahigh-resolution map of Antarctica made up of nearly 1,100 hand-selected scenesthat will improve research and provide a detailed base to measure changes.
TheLandsat Image Mosaic of Antarctica, orLIMA, is set to be made public on Nov. 27, NASA said. It's a partner in the project with the U.S. Geological Survey, the U.S. National Science Foundation and the British Antarctic Survey.
The images are being assembled digitally to produce a seamless, cloud-freemap of the vast, frozen continent. The map will be 10 times more detailed than any previous image, NASA said on its website.
Themap will be available in four versions to cater to different needs. It will be accessible to the general public through the internet.
"The image mosaic will …be a valuable data source for science and logistics activities and provide a baseline for measuring change," the British Antarctic Survey said in its annual report.
The Landsat 7 satellite took most of the pictures, but British researchers and NASA provided some.NASA images were needed to fill the area around the geographic South Pole because Landsat 7's near-polar orbit does not cover the pole.
