File type specification:
The gbm file extension is associated with the MapServer, a dynamic link library for Windows used to create vector and raster color maps. Created by Graticule.
The gbm file stores bitmap data created in the MapServer.
This gbm 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.
