BNA file extension - Atlas Boundary data

What is bna file? How to open bna files?

The bna file extension is used for older Atlas Boundary format.

The BNA format is an ASCII exchange format for 2D vector data supported by many software packages. It only contains geometry and a few identifiers per record. Attributes must be stored into external files. It does not support any coordinate system information.

This bna file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
