Comments

National map data is published by Ordnance Survey (https://www.ordnancesurvey.co.uk/) for Great Britain and is open data: https://www.ordnancesurvey.co.uk/opendatadownload/products.html

Ordnance Survey's OpenData suite of digital products includes 1:250,000 scale raster mapping for all of Great Britain, and additional national mapping at higher resolution (OS StreetView, OS Open Map - Local, OS Open Roads, OS Open Rivers and OS Boundary-Line).

The Ordnance Survey's OpenData product suite is released under the Open Government Licence, which complies with the Open Definition. The mapping is actively maintained and updated regularly.

As Ordnance Survey is the national mapping agency for Great Britain only, the coverage excludes Northern Ireland, the Isle of Man and the Channel Islands.

Separate national mapping data for Northern Ireland is produced by Ordnance Survey for Northern Ireland (OSNI) (https://www.nidirect.gov.uk/ordnance-survey-of-northern-ireland). However open data mapping for Northern Ireland is not currently available at resolutions of 1:250,000 or better.(https://www.nidirect.gov.uk/index/information-and-services/property-and-housing/your-neighbourhood-roads-and-streets/ordnance-survey-of-northern-ireland/product-range/digital-products.htm). OSNI mapping is available for re-use on commercial terms.

Data is correct. I included this as bulk although Northern Ireland is not a part of this dataset.
