The NY Times ran a piece about a new LIDAR (Light Detection And Ranging) flyover to help create a more accurate, up-to-date 3D LIDAR image of New York City.
The aircraft, with a pilot and laser sensor operator for its crew, scanned the urban canyons of the city at about 3,500 feet in nine six-hour, post-midnight flights from April 14 to April 30, said a spokesman for Sanborn, the Colorado-based mapping firm hired for the task.
The focus was on how the roofs can be mapped to find the solar potential for rooftops in NYC but I can imagine a lot more things that can be done with it. I hope its accessible through NYC Data Mine.
