LIDAR



http://imaging.geocomm.com/gallery

LIDAR (Light Detection and Ranging) is an optical remote sensing technologay that measures different properties of dispersed light to find range or other information of a distant target. The difference between lidar and radar is that lidar uses shorter wavelenths of the electromagnetic spectrum, generally close to infrared.
Here is a LIDAR image of ground zero after the Sept. 11 attacks.
