Questions & Answers
BNA files: Frequently Asked Questions
What are BNA files?
The BNA file format is an Atlas Boundary format used for defining geographic boundaries. It is developed by the Open Knowledge Foundation and is used for creating data-driven maps with data. The file format contains a set of JSON objects that define the boundary of an area. The data included in the file helps in defining the area covered by the boundary, such as the name, geometry, and other attributes. The .bna file format is widely used in various mapping and geographical data applications to define geographic boundaries.
