Before and after 3D topography showing the collapsed front of a multistory building, Orange Beach, AL: In these Lidar images, the rectangular mounds are buildings measured by the airborne laser mapping system. The five-story building in the center of the image was perched on top of a dune that was eroded during Hurricane Ivan. The Gulf-front portion of the five-story building collapsed creating a large rubble mound. The small bumps (highs) on the road behind the Gulf-front buildings in the pre-Ivan image are vehicles captured by the airborne laser mapping system. The pre-Ivan topography was measured with USACE Joint Airborne Lidar Bathymetry Technical Center of Excellence - CHARTS lidar system. The post-Ivan topography was measured with NASA's EAARL.
