"DigitalGlobe, provider of imagery for Google Earth, said WorldView I, a new high-resolution satellite to be launched on Tuesday, will produce one-half meter resolution images for commercial use, and will be able to collect over 600,000 square kilometers of imagery each day, up from each week."

"Half-meter resolution means the satellites can record images with enough resolution to make it possible to identify objects as small as a half-meter across."
