Vice President’s Digital Earth Vision
“A multi-resolution, three-dimensional representation of the planet, into which we can embed vast quantities of geo-referenced data”.
“... zoom in, using higher and higher levels of resolution, to see continents, then regions, countries, cities, and finally individual houses, trees, and other natural and man-made objects.
--The Digital Earth Vision as articulated in an address given at the California Science Center in Los Angeles by Vice President Al Gore
