Bathymetry 1M GRID of St. John (South Shore - Area 1), US Virgin Islands, 2004, UTM 20 WGS84

Metadata Updated: May 10, 2024

This dataset contains an ESRI Grid with 1 meter cell size representing the bathymetry of the south shore of St. John, US Virgin Islands. Due to the large file size of the St. John project area, it was divided into four component grids for improved manageability, named STJ_1m_grid1, STJ_1m_grid2, STJ_1m_grid3, and STJ_1m_grid4 from west to east. 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 Grid. 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.
