This lidar survey was acquired to document the change of several different barrier island systems resulting from Hurricane Isaac. The survey supports detailed studies of Louisiana, Mississippi and Alabama barrier islands that resolve annual and episodic changes in beaches, berms and dunes associated with processes driven by storms, sea-level rise, and even human restoration activities.
