Description: This image represents a 1x1 meter depth (bathymetry) surface for areas inside Buck Island Reef National Monument (BIRNM). It was collected by Fugro LADS, in collaboration with NOAA's Biogeography Branch, the University of New Hampshire and the National Park Service, from 2/21/2011 to 2/22/2011 using LADS (Laser Airborne Depth Sounder) Mark II LiDAR system. Depths between 0 and 49 m were surveyed, producing a 1x1 m bathymetry and 3x3 m reflectivity (intensity) surface. Soundings were positioned relative to the horizontal coordinate system (NAD83 UTM 20 N) and to the vertical coordinate system (MLLW). The bathymetry surface was corrected for sensor offsets, latency, roll, pitch, yaw, static draft, the influence of tides using CARIS HIPS & SIPS software. This depth image (and derivatives from it) was used to update nautical charts in the area and to develop a new benthic habitat map for BIRNM in 0 to 50 meters of water.
