Record 19 of 494 for U. S. Virgin Islands region search.
||Bathymetry 10M GRID of St. Thomas, US Virgin Islands, 2004, UTM 20 WGS84
||This dataset contains an ESRI Grid with 10 meter cell size representing the bathymetry of the south shore of St. Thomas, 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 10, 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.
