Marrying Maps to Data for a New Web Service - New York Times: "SAN FRANCISCO, July 14 - In 1991, David Gelernter, a computer scientist at Yale, proposed using software to create a computer simulation of the physical world, making it possible to map everything from traffic flow and building layouts to sales and currency data on a computer screen.

Mr. Gelernter's idea came a step closer to reality in the last few weeks when both Google and Yahoo published documentation making it significantly easier for programmers to link virtually any kind of Internet data to Web-based maps and, in Google's case, satellite imagery."
