GeoPackage overview
The Open Geospatial Consortium (OGC) defines GeoPackage (*.gpkg) as an open, non-proprietary, platform-independent, standards-based data format for geographic information systems (GIS). It is designed to be a lightweight format that can contain large amounts of varied and complex data in a single, easy-to- distribute and ready-to-use file. GeoPackage is natively supported by numerous software applications.
GeoPackage offer users the following benefits:
The single file is easy to transfer and offers a rich end-user experience.
Attribute names are not limited in length, making the format user friendly.
The file size limit is large at 140 TB.
A file size limit could be imposed by the file system to which the file is written.
It supports raster, vector, and database formats, making it a highly versatile solution.
It is an OGC standard.
In most cases, it is a plug-and-play format.
