A LIDAR map uses laser as opposed to radio or microwave radiation, and thus is known as a type of remote sensing that uses light detection and ranging. This map combines the use of aerial photography and LIDAR in order to produce a map that shows the levels of flooding that occurred throughout New Orleans as part of Hurricane Katrina. This was particularly useful to the NOAA office of response and restoration, FEMA and the U.S. Coastguard in locating the highly flooded areas and the hazardous materials in said waters.
