NASA releases high-resolution map of Antarctica mongabay.com November 27, 2007
The map, called the Landsat Image Mosaic of Antarctica, is made up of about 1,100 images from the NASA-built Landsat 7 satellite. The mosaic gives nearly a cloudless view of the southern-most continent with a resolution 10 times greater than ever before.
NASA says the map will help researchers better plan scientific expeditions. ![]() The enhanced resolution of the new mosaic map is shown in comparison to three previous Antarctic mosaics. Each pixel from the new mosaic is roughly the half the size of a basketball court. An earlier satellite mosaic created in 1996 from the Advanced Very High Resolution Radiometer had pixels a little more than twice the size of Vatican City. Click image to enlarge.
