Bathymetry

Bathymetric Attributed Grid (BAG) Data
Survey products may use different units, datums or projections than the associated survey. Please consult product-specific metadata for additional details.
The BAG format is a gridded, multi-dimensional bathymetric data file (see Open Navigation Surface). Readable with various applications such as the free CARIS Easy View, ESRI ArcGIS or open source GDAL. The BAGXYZ files are ascii representations of the BAG data in XYZ format, but do not include uncertainty.

H12250_MB_50cm_MLLW_1of3.bag	254.0KB
H12250_MB_1m_MLLW_2of3.bag	82.34MB
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.
