The radar altimeter on the European ERS satellites made it possible to measure the change in topography of the Antarctic ice sheets (upper image) and estimate sea-ice thickness in the Arctic (lower image). Although a remarkable scientific achievement, the maps demonstrate the shortcomings of the existing satellite systems - there is a large data gap at each pole and the most dynamic areas at the outer edges of the ice sheets are not covered.
