Combined Authorities: Digital Vector Boundaries for England

December 2025 boundaries provide the full-resolution digital vector extent for Combined Authorities in England, typically defined by the Mean Low Water mark. The dataset contains intellectual property rights from both Ordnance Survey and the Office for National Statistics. It is available via multiple geospatial web services, including a Feature Access Service and a WFS Server.

Use Cases

• Mapping regional governance structures based on the official Combined Authority boundaries.
• Performing spatial joins for demographic or economic data using the high-resolution vector polygons.
• Creating base maps for regional planning and analysis in England.
• Integrating administrative boundaries into GIS systems via the provided WFS service.

Strengths

• Provides full-resolution (BFE) vector boundaries, a specific and detailed geographic representation.
• Contains intellectual property from two authoritative UK sources: Ordnance Survey and ONS.
• Available on multiple platforms, indicating its importance and widespread use.

Limitations

• Key metadata such as row count, file size, specific column names, and license details are missing from all sources.
