Combined Authorities: Super-Generalised Boundaries for England

Ordnance Survey and Office for National Statistics vector boundaries define the administrative geography of England's Combined Authorities. The dataset provides a 'Super Generalised' (200m) representation, clipped to the Mean High Water coastline mark. Its cross-platform presence on UK and EU open data portals signals its importance for official geographic referencing.

Use Cases

• Mapping regional governance structures based on the official Combined Authority boundaries.
• Performing spatial joins for demographic or economic statistics using the 200m generalised geometry.
• Creating base maps for regional planning and policy analysis in England.
• Integrating administrative geography into GIS systems via the provided WFS or FeatureServer endpoints.

Strengths

• Contains intellectual property from two authoritative UK sources: Ordnance Survey and the Office for National Statistics.
• Provides a consistent, generalised (200m) boundary representation suitable for small-scale mapping and analysis.
• Available via multiple access methods (WFS, FeatureServer) facilitating integration into geospatial workflows.

Limitations

• Sources conflict on the reference date: one platform lists December 2025, another lists December 2023.
• Key metadata such as row count, file size, and specific license terms are not provided on any platform.
• The 'Super Generalised' scale (200m) is not suitable for high-resolution or parcel-level analysis.
