Combined Authorities in England, Super Generalised Boundaries from March 2017

March 2017 boundaries for Combined Authorities in England are provided in five vector resolutions, from full detail to ultra generalised. The dataset contains intellectual property from both Ordnance Survey and the Office for National Statistics. File sizes range from 22 KB for the most simplified version to 2 MB for the full-resolution, coastline-clipped version.

Use Cases

• Create simplified regional maps based on the super generalised (200m) or ultra generalised (500m) boundaries.
• Perform spatial joins with other UK datasets using the full-resolution boundaries clipped to the coastline.
• Visualize the extent of Combined Authorities for web mapping applications using the smaller file size generalised versions.

Strengths

• Offers five specific boundary resolutions, including super generalised (200m) and ultra generalised (500m).
• File sizes are explicitly listed, with the smallest being 22 KB for the ultra generalised version.
• Contains authoritative intellectual property from Ordnance Survey and the Office for National Statistics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is specific to a single snapshot date (March 2017) and may not reflect later boundary changes.
