Latest County (Boundary)

Correspondance table reference: TBC Size: The combined size of the layer(s) in this feature service is approximately 53.8 MB Description: Counties were formerly administrative units across the whole of the UK. Due to various administrative restructurings, however, the only administrative areas still referred to as ‘counties’ are the non-metropolitan (shire) counties of England. The English metropolitan counties, although no longer administrative units, are also used for statistical purposes. Which layer should I choose from the list of layers below? This dataset is available in four layers: BFE , BFC , BGC and BSC . Select the layer that best suits your intended use. For analytical work, use the full-resolution BFC or BFE layers. For mapping or visualisation, use the generalised BGC or BSC layers. Layer Description BFE Full Extent – Full-resolution boundaries extend to the Extent of the Realm (Low Water Mark) and are the most detailed. BFC Full Clipped – Full-resolution boundaries clipped to the coastline (Mean High Water Mark). BGC Generalised Clipped – Generalised to 20 m and clipped to the coastline (Mean High Water Mark). BSC Super Generalised Clipped – Generalised to 200 m and clipped to the coastline (Mean High Water Mark).
