NOAA ESRI Geotiff- 1m Bathymetry of St. Croix (Buck Island), US Virgin Islands, 2004, UTM 20 WGS84
This dataset contains an ESRI Geotiff with 1 meter cell size representing the bathymetry of the north shore of Buck Island St. Croix, US Virgin Islands.NOAA's NOS/NCCOS/CCMA Biogeography Team and NOAA/NOS/OCS/HSD personnel, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 2/18/04 to 3/5/04. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides from NOAA COOPS. Data is in UTM zone 20 north, datum WGS84. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle with footprint size 3*3. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9 as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster', with cell size 1, was used to generate the final ESRI Geotiff. While the project was conducted to meet IHO Order 2 accuracy standards, there is a roll artifact (averaging 0.5m high) in the dataset that the user should take into consideration when performing any analysis.

"description": "This data package contains information about the geology and biology of the seafloor from approximately 0 to 1,830 meters in Buck Island Reef National Monument (BIRNM) St. Croix, U.S. Virgin Islands (USVI). It was created by delineating habitats visible in aerial photographs, lidar and multibeam echosounder imagery using ENVI's Feature Extraction (Fx) Module. The minimum polygon size for these habitat maps ranged from 100 square meters (in shallow <30 m depths) to 1000 square meters (in moderate 30 to 150 m depths) to 5,000 square meters (in deep >150 m depths). Additional habitat polygons were manually digitized if they were excluded during the feature extraction workflow. Polygon boundaries were smoothed in ArcGIS to reduce their pixelated appearance. A Classification and Regression Tree (CART) algorithm was used to classify each habitat polygon using georeferenced underwater video & photos collected using SCUBA divers, drop-cameras and remotely operated vehicles (ROVs). Major and detailed geomorphological structure, percent hardbottom, major and detailed biological cover and live coral cover were identified for each polygon. The moderate and deep maps mark the first time that habitats deeper than approximately 30 meters have been mapped in the Monument. These habitat maps will provide a baseline for future biological monitoring studies in BIRNM.",
