GeoServer is a web service for publishing your geospatial data using industry standards for vector, raster and mapping. It powers a number of open source projects like GeoNode and geOrchestra and it is widely used throughout the world by organizations to manage and disseminate data at scale.

GeoPackage is becoming a pervasive tool to share data among systems. But how well does it transfer meta-information, and how well does it handle large datasets? The presentation will introduce the work GeoSolutions performed during OGC Testbed 16, to answer those questions. In particular:

• An introduction to two large vector datasets by Ordnance Survey, ZoomStack and MasterMap topography.
• Embedding full meta-information in a GeoPackage, including metadata, styles and icons, as well as operational pictures and provenance information.
• Handling arrays and enumerated fields in an efficient, queryable way.
• Optimizing the internal structure of a GeoPackage for more efficient data retrieval.
• Splitting large GeoPackages in parts to gain both efficiency and ease of update.

In addition to the above, we’ll discuss handling large raster GeoPackages and how GeoServer handles all of the above.
