The Bathymetric Attributed Grid
([BAG](https://en.wikipedia.org/wiki/Bathymetric_attributed_grid)) is an
open specification and C++/Python library for representing bathymetric
data as grids of the best available characterization of the true depth
of the seafloor.
The [BAG
specification](https://bag.readthedocs.io/en/master/fsd/index.html) has
been in use for conveying and archiving bathymetry, uncertainty, and
metadata by [NOAA Office of Coast
Survey](https://www.ngdc.noaa.gov/mgg/bathymetry/hydro.html) for close
to 20 years. The BAG format was developed and is maintained by the [Open
Navigation Surface Working Group](https://www.opennavsurf.org/), a
collaboration between NOAA, [UNH JHC/CCOM](https://ccom.unh.edu) as well
as other interested parties. The format is used by the US Navy as well
as other hydrographic offices and academic partners around the world.
Participation in OSS-Fuzz will enhance automated testing for Open
Navigation Surface BAG library, helping to ensure correctness for this
reference implementation of the BAG specification while also uncovering
potential security vulnerabilities in this important piece of global
spatial data infrastructure.
