Latest Local Authority District (Boundary)

Which layer should I use? (choose from the list 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). Layer Description: Each Local Authority District (LAD) had responsibility for local planning, housing, local highways, building, environmental health, refuse collection and cemeteries as part of the two tier administrative system, along with the counties. Change log: 18/05/2026: Initial release如何选择适配的图层？（请从以下列表中选取）本数据集包含BFE、BFC、BGC及BSC四种图层，请根据实际使用需求选择最适配的图层。若用于分析工作，请使用全分辨率的BFC或BFE图层；若用于制图或可视化展示，请使用经简化处理的BGC或BSC图层。 图层说明： BFE：全范围（Full Extent）图层——全分辨率边界延伸至领海范围（低潮线），细节最为丰富。 BFC：全裁剪（Full Clipped）图层——全分辨率边界经裁剪至海岸线（平均高潮线）。 BGC：简化裁剪（Generalised Clipped）图层——已简化至20米精度，并裁剪至海岸线（平均高潮线）。 BSC：超简化裁剪（Super Generalised Clipped）图层——已简化至200米精度，并裁剪至海岸线（平均高潮线）。 图层说明： 各地方当局辖区（Local Authority District, LAD）作为两级行政体系的组成部分，与郡级行政单位一同承担地方规划、住房保障、地方道路管理、建筑监管、环境卫生、垃圾收运及公墓管理等职能。 更新日志：2026年5月18日：首次发布
