GeoPackage overview
The Open Geospatial Consortium (OGC) defines GeoPackage (*.gpkg) 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.
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.
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.
OS Open Rivers is supplied as a national GeoPackage file.
Attribute mapping
The naming of attributes between GeoPackage and GML is very similar as both formats do not limit the number of characters for an attribute name. The following tables map the GML attribute name to its GeoPackage equivalent for the WatercourseLink and HydroNode features.
