2011 Middle layer Super Output Area (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: Middle layer Super Output Area boundaries are a polygon representation of MSOAs. They were created and designed to improve the reporting of small area statistics. Change log: 20/05/2026: Initial release应选择何种图层？（请从以下列表中选取） 本数据集共包含四种图层：BFE、BFC、BGC与BSC，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，则请使用经过概化处理的BGC或BSC图层。 图层说明： BFE 全范围图层（Full Extent）：全分辨率边界延伸至国家管辖范围（低潮线，Low Water Mark），为细节最为丰富的图层。 BFC 全裁剪图层（Full Clipped）：全分辨率边界已以平均高潮线（Mean High Water Mark）为基准，裁剪至海岸线。 BGC 概化裁剪图层（Generalised Clipped）：已概化至20米精度，并以平均高潮线（Mean High Water Mark）为基准裁剪至海岸线。 BSC 超级概化裁剪图层（Super Generalised Clipped）：已概化至200米精度，并以平均高潮线（Mean High Water Mark）为基准裁剪至海岸线。 图层说明：中层超级输出区（Middle Layer Super Output Area，MSOA）边界为MSOA的多边形矢量表示，其设计初衷为优化小区域统计数据的报告发布工作。 更新日志：2026年5月20日：首次发布
