Description: This image represents a LiDAR (Light Detection and Ranging) 0.3x0.3 meter resolution relative seafloor reflectivity surface. The image's horizontal coordinate system is NAD83 UTM 20 North. Fugro LADS acquired bathymetry and relative seafloor reflectivity between 1/29/2011 - 2/28/2011. Bathymetry and reflectivity data were acquired using a LADS (Laser Airborne Depth Sounder) Mark II Airborne System from altitudes between 1,200 and 2,200ft at ground speeds between 140 and 175 knots. The 900 Hertz Nd: YAG (neodymium-doped yttrium aluminum garnet) laser (1064 nm) acquired 3x3 meter spot spacing and 200% seabed coverage. Depths between 3 and 40 m were surveyed, producing a 3x3 m bathymetry and 3x3 m reflectivity surface. These surfaces were resampled to 0.3x0.3 m to match the spatial resolution of the orthophotos collected by the U.S. Army Corps of Engineers in 2012.
