Combined Authorities in England, Super Generalised Boundaries from March 2017

Office for National Statistics provides digital vector boundaries for Combined Authorities in England as of March 2017. The dataset includes five boundary versions, from full resolution to ultra generalised (500m), each clipped to the coastline. It contains both Ordnance Survey and ONS Intellectual Property Rights.

Use Cases

• Mapping regional governance structures based on the provided vector boundaries.
• Performing spatial joins with other datasets using the super generalised (200m) boundaries for computational efficiency.
• Analyzing coastal administrative extents using the boundaries clipped to the Mean High Water mark.

Strengths

• Provides five distinct boundary resolutions, with file sizes ranging from 22 KB to 2 MB, allowing for flexibility in application.
• Contains intellectual property from both Ordnance Survey and ONS, indicating authoritative source data.
• Boundaries are temporally specific, representing the administrative geography as of March 2017.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
