Geopackage is an OGC-compliant open file format for geospatial data that allows users to store data in a single file. As a file-based database built with SQLite, Geopackage stores vector and raster data, QGIS project files, and default symbology together, making Geopackage an efficient way to manage and share project data. This webinar reviews Geopackage specifications and demonstrates how Geopackage in QGIS can be used to store, analyze, and exchange geospatial data within the QGIS environment.
