Bathymetry

Survey products may use different units, datums or projections than the associated survey. Please consult product-specific metadata for additional details.
Variable Resolution Bathymetric Attributed Grid
H11302_MB_VR_MLLW_1of1.bag	750.87MB	The Variable Resolution BAG format is a gridded, multi-dimensional, multi-resolution bathymetric data file (see Open Navigation Surface). Currently supported with open source GDAL. The BAGXYZ files are ascii representations of the BAG data in XYZ format, but do not include uncertainty.
NOAA/NOS Sounding Data
Download data from the Point Store database via NEXT (NCEI Extract System). Point soundings are from the survey Smooth Sheet or of similar density. Depths in meters. Horizontal datum is (converted to) NAD83 if possible. Vertical datum is (converted to) Mean Lower Low Water if possible. Please check the associated metadata to confirm the correct datums. The data file format is : SurveyID, Long, Lat, Depth.
H11302		XYZ format.
