Local Authority District Boundaries for Great Britain, December 2009

Office for National Statistics provides digital vector boundaries for Local Authority Districts in Great Britain as of December 2009. The dataset includes five boundary resolutions, from full resolution to ultra generalised (500m), each clipped to the coastline. It contains both Ordnance Survey and ONS Intellectual Property Rights.

Use Cases

• Create thematic maps of Great Britain based on the ultra generalised (500m) boundaries for web visualization.
• Perform spatial analysis of administrative units using the full resolution boundaries clipped to the coastline.
• Integrate historical district boundaries into a geographic information system using the provided GeoJSON or KML formats.

Strengths

• Offers five specific boundary resolutions, including ultra generalised (500m) at 367 KB for lightweight use.
• Provides clear file size estimates for each resolution, such as 49 MB for full resolution clipped to the coastline.
• Includes multiple access methods via REST URLs for ArcGIS INSPIRE View and Feature Download services.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a specific historical snapshot (December 2009) and may not reflect current boundaries.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
