GeoPackage (*.gpkg) is an open, non-proprietary, platform-independent, standards-based data format for geographic information systems (GIS), as defined by the Open Geospatial Consortium (OGC). 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.
The naming of attributes between GeoPackage and the Geography Markup Language (GML) file is very similar as GeoPackage files are not limited in the number of characters for an attribute name.
Therefore, the following tables map the GML attribute name to the attribute name in the GeoPackage files. The GML contains an attribute which describes the geometry of the feature; this is not applicable for a GeoPackage file as they are separated by their geometry.
Please note that the use of an asterisk symbol (*) in the following tables indicates that a particular attribute is not mapped to GML.
GeoPackage offers users the following benefits:
The single file is easy to transfer and offers the end-user a rich experience.
Attribute names are not limited in length, making the format user-friendly.
The file size limit is very large at 140 TB*
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.
* A file size limit might be imposed by the file system to which the file is written.
For information on how to open, use and understand a GeoPackage dataset, please refer to our Getting Started with GeoPackage guide. For further information on GeoPackage, please see the GeoPackage website.
