For years map-makers stood tip-toe on tall peaks to survey the world. Then came the airplane, giving cartographers a bird's eye view. Now satellites in space have such high resolution that they can distinguish a rock from a shrub. In this hour of To the Best of Our Knowledge, the mapping revolution: how new technology is changing the way we see our world. Also, a cosmic cartographer maps the universe.
Margaret Geller teaches astronomy at Harvard and does research at the Smithsonian Astrophysical Observatory. She tells Steve Paulson why she's working on mapping the universe, charting patterns in the largest forms in nature; and that measuring space on the cosmic scale also reveals information about the past. Also, John Radke, who teaches geographical information science at Berkeley University, tells Jim Fleming about some of the new mapping technologies made possible by satellites and computers.SEGMENT 2:
