GeoPackage (.gpkg) is an open, non-proprietary, platform-independent, and standard data format for geographic information systems (GIS), as (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.
GeoPackage offers users the following key features and 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, so lots of data can be easily accommodated (please note that a file size limit may be imposed by the file system to which the file is written).
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.
Data will be supplied in British National Grid (ESPG:27700), World Geodetic System (WGS84: EPSG: 4326), or British National Grid + ODN Height (EPSG: 7405), depending on your selection when ordering OS NGD data.
The following sub-sections provide step-by-step instructions on how to access GeoPackage data via various GIS software packages, all current versions of these support GeoPackages natively.
It is possible to use Extract, Transform, Load (ETL) tools to convert the data into different formats and to load into databases.
