Great Britain Local Authority District Boundaries from December 2009

Great Britain's Local Authority District boundaries as of December 2009, provided by the Office for National Statistics. The dataset includes vector boundaries at multiple 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

• Map historical administrative units based on the December 2009 boundaries.
• Perform spatial analysis on generalised (20m) or ultra generalised (500m) boundary files for performance.
• Integrate clipped coastline boundaries into regional planning or demographic studies.

Strengths

• Provides five distinct boundary resolutions, including full resolution and ultra generalised (500m) versions.
• Specific file sizes are listed, such as 6 MB for the generalised (20m) clipped version.
• Contains intellectual property rights from both Ordnance Survey and the Office for National Statistics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to a single snapshot from December 2009.
• Row count is unknown, which may limit suitability assessment for some analyses.
