Combined Authorities in England: Generalised Clipped Boundaries from March 2017

Five vector boundary resolutions for Combined Authorities in England as of March 2017, ranging from full resolution to ultra generalised (500m). The data contains both Ordnance Survey and Office for National Statistics intellectual property rights. File sizes for the clipped coastline versions range from 22 KB for the ultra generalised version to 2 MB for the full resolution version.

Use Cases

• Create thematic maps of Combined Authorities based on the provided vector boundaries.
• Perform spatial analysis on administrative regions using the generalised (20m) or super generalised (200m) boundaries for computational efficiency.
• Integrate boundary data into Geographic Information Systems (GIS) for regional planning based on the coastline-clipped versions.
• Visualise the extent of Combined Authorities for public information services using the ultra generalised (500m) boundaries.

Strengths

• Provides five distinct boundary resolutions, including full resolution and four generalised/clipped versions.
• Specific file sizes are listed for each boundary type, with the ultra generalised version being 22 KB.
• Contains intellectual property rights from two authoritative sources: Ordnance Survey and the Office for National Statistics.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is specific to a single snapshot in time (March 2017), which may limit current applicability.
