This is a map of Antarctic surface ice velocity: the speed at which glaciers flow. It was produced by researchers at the University of California Irvine and the Jet Propulsion Laboratory, using radar interferometry and multiple satellite passes to produce a map 10 times more accurate than previous maps.

An international team of researchers has scanned and digitized 2 million records from pioneering aeroplane radar expeditions that criss-crossed the frozen continent in the 1960s and 1970s. […] The digitized data extend the record of changes at the bottom of the ice sheet, such as the formation of channels as Antarctica’s ice flows, by more than two decades.” (Modern radar mapping of Antarctica apparently only began in the 1990s.)
