jerz.setonhill.edu/ design/WTC/index.htmlLIDAR (light detection and ranging) is used to
map topographical data. I chose this LIDAR image of the ground zero, the World Trade Center disaster area because of it familiarity with most people. The image on the left is the before shot. You can see the small(er) building with the dome at the top in front of the towers. In the 'after' shot the domed building is on the left. The towers are completely gone. LIDAR imaging leaves a haunting picture of the area
that remained.
