description: This dataset provides the Country boundary for Northern Ireland as a polygon layer, delineating the land area at the country level. It is derived from the OSNI (Ordnance Survey Northern Ireland) Largescale database, with the boundary topologically cleansed and attributed to form a seamless, consistent dataset. Published as open data in 2016, it is distributed via the Office for National Statistics open data channels, though it is explicitly noted as not being an official ONS statistical product. It is suited to mapping and geographic analysis requiring accurate national-level boundary geometry for Northern Ireland.
