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.
