This lidar survey was acquired to document the short- and long-term changes of several different barrier island systems. Specifically, this survey supports detailed studies of the Chandeleur Islands that resolve annual changes in beaches, berms and dunes associated with processes driven by storms, sea-level rise, and human restoration activities.
