Satellite Imagery Comes Down to Earth
It used to be that, to get a bird’s-eye view of your house, you had to be a bird — or somebody in the intelligence community. That’s not true anymore. The advent of software from Google Inc. of Mountain View, Calif., Microsoft Corp. of Redmond, Wash., and Yahoo! Inc. of Sunnyvale, Calif., as well as a planned relaunch of an application from AOL’s subsidiary Mapquest Inc. of Denver has brought satellite and airborne imagery down to Earth. As a result, people can fly, in a virtual sense, over...
