The Bathymetric Attributed Grid (BAG) is a hydrographic exchange data format developed and maintained by the ONS-WG (Open Navigation Surface Working Group).
The HydrOffice BAG library provides access to BAG-specific features, as well as a collection of tools to verify and manipulate BAG data files.
BAG Explorer is a light application, based on HDF Compass and the HydrOffice BAG library tools, to explore BAG data files. It is written in Python 2.7, and the current release is 0.3.1.
BAG Explorer provides a mechanism to explore the tree-like structure of a BAG file, to visualize and validate the XML metadata content, to inspect the tracking list, and to plot the elevation and the uncertainty layers.
