Bathymetric Attributed Grid (BAG) is a file format designed to store and exchange bathymetric data.
The implementation of the format was triggered by the large adoption of gridded bathymetry and the need of transferring the required information about bathymetry and associated uncertainty (i.e., metadata) between processing applications. The BAG format was designed to provide a container able to transfer all of the relevant information of a given bathymetric project. The creation and the access to the format is supported through a code base implemented in C++.[2][3]
The format is supported by The Open Navigation Surface Working Group whose mission is to ensure its continued development.
The format can be accessed using GDAL, currently in read-only mode.[4]
History

The project started with the creation of
The following meeting was held on 18–22 July 2005 resulting in an alpha building of the library. The use of the library was then demonstrated at Shallow Survey 2005 conference using a number of processing applications (i.e., IVS Fledermaus, CARIS HIPS, and SAIC SABER).[2][7]
The first stable version (v.1.0.0) of the library was released on 8 Aprile 2006.[8]
In April 2012, the
With release 1.6, the optional support for variable resolution digital elevation model was introduced.
