I received some unclass base maps from NGA that showed up with .bundle extensions but is there a way to extract that format into ArcPro 2.7/2.8 so we can view the maps? Any help would be greatly appreciated.
from Extract Package (Data Management)—ArcGIS Pro | Documentation
perhaps, but untested
When extracting vector tile packages (.vtpk), the contents of the package will be extracted to the output folder. The cache storage format can be converted from compact (.bundle files) to exploded (.pbf files) using the Storage Format Type parameter.
Export Tile Cache (Data Management) with storage format "Exploded".
Check if this works.
