To judge the effectiveness of current and future beach or barrier island re-nourishment projects, LIDAR and 3D LASER scanner data was used to map sections of Folly Beach, South Carolina that underwent re-nourishment in the summer of 2005. The LIDAR data was flown as part of NOAA's Coastal Mapping Program and provided base information for the project with 15 cm vertical accuracy and sub-meter horizontal accuracy. Using hand-held GPS units, 3D LASER scanner locations were marked. The scanner was used to obtain 3D scans of beach profiles to sub-centimeter accuracy (horizontal) and millimeter accuracy (vertical). The scanner has a maximum field of view of 270 degrees horizontally and 360 degrees vertically. It can acquire both digital imagery and varying resolutions and fields of view for 3D scans. The LIDAR and LASER data sets were integrated to provide detailed mapping of the barrier island in both spatial and temporal realms. The maps created from the project will be used not only to assess re-nourishment profiles, but as base-line information for future coastal process and erosion studies at Folly Beach. This data will be useful in the development of future beach erosion control plans and to help create a hurricane-strength to erosion curve for the island.
