What is a GSB file?
GIS file used by spatial visualization and mapping products developed by Golden Software; contains geographical boundaries, such as country, state, or county boundaries; used for importing boundaries and then overlaying them with spatial data sets.
Several prefabricated GSB files are made available at the Golden Software website so that users don't have to make geographical boundaries from scratch.
