Global positioning systems have become surprisingly accurate in the 2D landscape – certainly much more accurate than what we would have expected about 10 years ago. However, altitude measurements aren't on the same level. However, researchers at the University of Warmia and Mazury in Poland and at Ohio State University said they have developed a software that is improving vertical accuracy and will enhance applications that are used in potentially hazardous regions at high altitudes.
They also claim that their software could be used to measure how quickly glaciers at high altitudes are melting.
