Before and after 3D topography/bathymetry showing the breach through the barrier island, Pine Beach, AL: At the time of the post-storm lidar survey, the channel had scoured to a depth of 1.8 m. The pre-Ivan topography was measured with NASA's Airborne Topographic Mapper (ATM). The post-Ivan elevations were measured with NASA's EAARL, which was able to seamlessly measure topography and bathymetry across the air-water interface with no data loss in shallow water. Note the new houses that were built between the surveys (houses appear as rectangular mounds; their hotter colors indicate higher elevations.)
