Combined Authorities Boundaries in England, March 2017

England's Combined Authorities digital vector boundaries as of March 2017, provided by the Office for National Statistics. The dataset includes five boundary versions, from full resolution to ultra generalised (500m), each clipped to the coastline. File sizes range from 22 KB for the ultra generalised version to 2 MB for the full resolution clipped version.

Use Cases

• Map creation and visualization based on the provided ultra generalised (500m) boundaries for web mapping.
• Spatial analysis of Combined Authorities based on the full resolution boundaries clipped to the coastline.
• Data integration with other geographic datasets based on the generalised (20m) or super generalised (200m) boundary files.
• Compliance with INSPIRE directive mapping services based on the linked ArcGIS REST services.

Strengths

• Provides five distinct boundary resolutions, with file sizes explicitly listed (e.g., 22 KB for ultra generalised).
• Contains intellectual property rights from both Ordnance Survey and the Office for National Statistics.
• Offers multiple access methods including direct download and ArcGIS REST services for INSPIRE compliance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is specific to a single snapshot in time (March 2017), limiting temporal analysis.
• Row count is unknown, which may limit suitability assessment for large-scale statistical projects.
