Combined Authorities: Ultra-Generalized Boundaries for England

Ordnance Survey and Office for National Services intellectual property underpins this official vector boundary data for England's Combined Authorities. The dataset provides ultra-generalized (500m) boundaries, clipped to the Mean High Water coastline mark. It is available for multiple reference years, including December 2020 and December 2025, and is accessible via multiple geospatial web services.

Use Cases

• Mapping regional governance structures based on official Combined Authority boundaries.
• Conducting spatial analysis of socio-economic indicators across these administrative units.
• Creating generalized, small-scale cartographic products using the 500m-clipped coastline data.

Strengths

• Contains intellectual property from two authoritative UK mapping and statistics bodies: Ordnance Survey and ONS.
• Provides boundaries for multiple specific reference dates (December 2020 and December 2025).
• Available via multiple standardized web services (Feature Access Service, WFS Server) for programmatic access.

Limitations

• Key metadata such as row count, file size, specific column names, and license details are not provided on any platform.
• The dataset's temporal coverage is unclear as sources list different 'as at' dates (2020 and 2025) without explanation.
• Descriptions are identical across platforms for different years, suggesting potential duplication or lack of version-specific documentation.
