The data, hosted by the NOAA Office for Coastal Management, can be customized and requested for free download through a checkout interface. An email provides a link to the customized data, while the original data set is available through a link within the viewer. download This dataset consists of locations below the surface of the water where the depth of water is precisely known relative to some reference. This dataset is used for volumes calculations, channel condition reports, and project mapping.

The NAD83 realization was assumed to be 2011. Data were converted to LAS format using LAStools txt2las. Data were converted to geographic coordinates using LAStools las2las and then transformed vertically to NAD83(2011) ellipsoid heights using NOAA VDatum. Files were then compressed to LAZ format using laszip. During the transform to ellipsoid heights, some data were lost because they fell outside the domain of the NAVD88 to IGLD85 conversion grids.
