Hurricane Ike Before and After
Lidar is an aerial surveying technique that uses laser to create extremely accurate maps of the ground elevation. The survey to the left, taken before Ike, shows a continuous dune ridge along Follets Island, between the highway and the beach. The post-Ike survey to the right shows storm scour channels carved through the beach and dunes. These scours removed up to 7 ft of sand, which was washed out to sea.
