GeoPackage Encoding Standard
A GeoPackage is a platform-independent SQLite database file that may contain:
- vector geospatial features
- tile matrix sets of imagery and raster maps at various scales
Since a GeoPackage is a database, it supports direct use, meaning that its data can be accessed and updated in a "native" storage format without intermediate format translations. GeoPackages are interoperable across all enterprise and personal computing environments, and are particularly useful on mobile devices like cell phones and tablets in communications environments with limited connectivity and bandwidth. This OGC® Encoding Standard defines the schema for a GeoPackage, including table definitions, integrity assertions, format limitations, and content constraints. The allowable content of a GeoPackage is entirely defined in this specification.
OGC GeoPackage reference implementation
The OGC GeoPackage reference implementation used for the Plugfest was created by the US Army Engineer Research and Development Center (ERDC). This raster tile pyramid GeoPackage was created with free imagery obtained from Geomatics Yukon, and covers an approximately 30 square-kilometer area centered on the City of Whitehorse. The OGC GeoPackage Plugfest reference implementation uses the Web Mercator (EPSG:3857) coordinate reference system, 256x256 pixel tiles, contains zoom levels 11-18, and is 135.25MB in size. The Python scripts used to create this GeoPackage can be found at https://github.com/GitHubRGI/geopackage-python.

This specification is currently stable, however, Working Groups are put in place to actively address future changes.The GeoPackage SWG group has a public page at: http://www.opengeospatial.org/projects/groups/geopackageswg
