Description: These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division. Data from Key West to the Marquesas Keys were acquired from 20140829 - 20140919 and 20160419 - 20160425 using a Riegl VQ880G and VQ820G system. Data to the west and south of the Marquesas were collected in 2011 with the SHOALS-1000T airborne lidar bathymetry system. The data includes topobathy data in an LAS 1.2 format file classified as unclassified (1), ground (2), noise (7), water column (25), bathymetric point (26), topobathy water surface (27), submerged object (29), and International Hydrographic Organization (IHO) S-57 object (30) in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. This data set may also include lidar intensity values and encoded RGB image values.These data are served to the public at the following NOAA site:The NOAA Bathymetric Data Viewer at - https://maps.ngdc.noaa.gov/viewers/bathymetry/In the Layers Window - select "Surveys with Bathymetric Attributed Grids (BAGs)" and zoom into the area around Key West and the Marquesas
