GeoTIFF of 3x3 m Relative Reflectivity for Buck Island, St. Croix, 2011, UTM 20N NAD83 (NCEI Accession 0131858)
Description
This image represents a LiDAR (Light Detection & Ranging) 3x3 meter resolution relative seafloor reflectivity surface for an area including and surrounding Buck Island Reef National Monument (BUIS), St. Croix in the U.S. Virgin Islands (USVI). The image's horizontal coordinate system is NAD83 UTM 20 North. Fugro LADS, in collaboration with NOAA's NOS/NCCOS/CCMA Biogeography Branch, the University of New Hampshire and the National Park Service, acquired bathymetry, relative seafloor reflectivity and hyperspectral imagery in St. Croix from 2/21 to 2/22/2011. Hyperspectral data were acquired using a Hyspex VNIR-1600 sensor. 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. In total, 32.2 square kilometers of LiDAR relectivity were collected between 0 m and 49 m in depth. Environmental factors such as wind strength and direction, cloud cover, water clarity and depth influenced the area of data acquisition on a daily basis. The data was processed using the LADS Mark II Ground System and data visualization, quality control and final products were created using CARIS HIPS and SIPS and CARIS BASE Editor. All users should individually evaluate the suitability of this data according to their own needs and standards.
