Sample data for the collections is available in GeoPackage and CSV (comma-separated values) formats.

One zip file of sample data is provided per OS NGD collection. Within each of these zip files, the individual feature types for each collection are separated into their own folder.

The sample data for each OS NGD collection covers three 10km by 10km areas in Great Britain: Exeter (England), Newport (Wales), and Inverness (Scotland). The exception to this is the OS NGD Boundaries Collection sample data which provides national coverage for Great Britain.

Please note that sample data is not available for the OS NGD Islands Address Collection.

Sample data always use the latest data schema version available for each collection.

Please note that as we are publishing three 10km x 10km sample data areas for most of the OS NGD collections, a small number of feature types are not represented within these areas and therefore their record counts will be zero:

• Landform Point (OS NGD Land Features Collection)

• Maintenance Point (OS NGD RAMI Collection)

• Railway Link Set (OS NGD Transport Network Collection)
