Profile comparison plotProfile Comparisons - at selected locations shore-normal transects were defined. Profiles along these transects were determined from lidar surveys obtained in September 1997 and September 1998. Each data point shown represents a laser spot elevation. All spot elevations within 1 meter of the shore-normal transect were used to construct the profiles.
