Bronze level automatically awarded US beta

This data has achieved Bronze level on 25 October 2015 which means this data makes a great start at the basics of publishing open data.

NOAA ESRI Grid - Unified 10m Bathymetric Slope, US Virgin Islands, St. Thomas, St. John, St. Croix, Puerto Rico (La Parguera, Culebra Island, Vieques Island, Tourmaline Bank, Mona Island) - Projects NF-04-06, NF-05-05, NF-06-03, NF-07-06, NF-08-04, NF-09-

Description

This dataset contains a unified ESRI Grid with 10x10 meter cell size representing the slope of selected portions of seafloor around Puerto Rico, St. Croix, St. Thomas and St. John in the US Virgin Islands, derived from data collected in 2004, 2005, 2006, 2007, 2008, and 2009. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Caribbean from 2/18/04 to 3/5/04, 2/1/05 to 2/12/05, 3/21/06 to 4/2/06, 4/14/07 to 4/27/07, 2/25/08 to 3/8/08, and 3/26/09 to 4/2/09. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) in 2004 and 2005, a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2006, 2007, 2008, and 2009, a moon pool flange-mounted Reson 8124 multibeam echosounder (200 kHz) for water depths of less than 75 meters in 2007, and a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of less than 75 meters in 2009. It was processed by a NOAA contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.x as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate the final ESRI Grid. The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.
