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).
