An LPK - ArcGIS Layer Package file is created and used by the ArcGIS program. The ArcGIS creates packaged files containing data and the associated map layer which the may imported and used with other maps and/or globes. The LPK can also be used for the convenient sharing of maps and associated data with anyone else that is using the software. The LPK file format can be opened for use by either ArcMap or ArcGlobe. Both the ArcMap and ArcGlobe are distributed in the ArcGIS software package.
