Record 20 of 494 for U. S. Virgin Islands region search.
||Bathymetry 10M XYZ of St. Thomas, US Virgin Islands, 2004, UTM 20N WGS84
||This dataset contains a comma-delimited ASCII XYZ text file with easting, northing, and depth in meters values for the bathymetry of the south shore of St. Thomas, US Virgin Islands. XYZ values are derived from a 10m resolution gridding process.
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, datum WGS84. The processed CARIS data was used to generate a CARIS BASE surface based on swath uncertainty with footprint size 3*3. A comma delimited ASCII XYZ file was then exported from the BASE surface.
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.
