The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC), collected single-beam and swath bathymetry data at the Chandeleur Islands, Louisiana in June of 2016. This USGS data release includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM). For further information regarding data collection and/or processing please see the metadata associated with this data release.
This USGS data release provides 437-line kilometers (km) of processed single-beam bathymetry (SBB) and Interferometric Bathymetry (IFB) data collected under USGS Field Activity Number (FAN) 2016-335-FA. This FAN encompasses two subfans each of which represents one research vessel (RV); the RV Sallenger (16BIM01) and the RV Jabba Jaw (16BIM02). The SBB and IFB point data (xyz) are provided in two datums; the International Terrestrial Reference Frame of 2008 (ITRF08) and ellipsoid height and the North American Datum 1983 (NAD83) in the CORS96 realization for the horizontal and the North American Vertical Datum 1988 utilizing the 2009 geoid (GEOID09) model (NAVD88g09) for the vertical. Additional files include trackline shapefiles, respective digital and handwritten field logs, and a comprehensive 50-meter Digital Elevation Model (DEM).| File Name and Description | Metadata (XML format) | Metadata (text format) | Download File |
