New LIDAR images taken in 2010 will reveal extremely fine detail of the9/11 development site. Using Remote-sensing technology to create the maps included aerial photography, laser-based instruments called LIDAR (light detection and ranging), and thermal sensors. Mounted on planes, LIDAR penetrated the heavy smoke rising from the devastated area and captured the first clear images of the scene.
Thermal imaging was used to determine where fires were still smoldering and, over time, the movement of these "hot spots" throughout the area.
