"A Game Changer" – New map of the warming world of Antarctica: "Up until now we had better maps of Mars"

"So far we had a better map of Mars than we had of Antarctica, but now it is the best-mapped continent," said Ian Howat, professor of earth sciences and director of the Byrd Polar and Climate Research Center at Ohio State University. "If you are someone who needs glasses to see, it's a bit like being almost blind and putting on glasses and seeing 20/20 for the first time."

This new high-resolution terrain map of the frozen continent of the earth will help researchers better track changes on the ice as the planet warms up. The new map has a resolution of 2 to 8 meters, compared with 1,000 meters, which was typical of previous maps.

Previous maps of the continent had a resolution that looked like seeing all of Central Park from a satellite, writes Shannon Stirone in the New York Times. With this new data it is now possible to look at the size of a car and in some areas even smaller. The data is so complete that scientists now know the height of every function on the continent up to a few feet.
