Abstract

It is one of the ironies of history that at the dawn of the year 2000, more precise radar-generated maps existed of Venus (courtesy of NASA’s Magellan imaging spacecraft) than of our Home Planet. Although some areas of Earth, including the United States, much of Europe, Australia and New Zealand, had digital maps at the 30 m resolution level, the vast majority of our world lacked such reliable data, primarily due to cloud cover in equatorial regions, which precluded imaging by optical satellites or aircraft. “Humans always want to know about their environment,” said German astronaut Gerhard Thiele, “and for the first time we will generate a coherent data set; a picture of the Earth.
