Great Britain Country Boundaries with Multiple Resolutions

Countries (December 2015) Full Clipped Boundaries in Great Britain provides digital vector boundaries for the constituent countries of Great Britain. The dataset includes five distinct boundary versions, ranging from full-resolution 'extent of the realm' to ultra-generalised (500m) versions clipped to the Mean High Water coastline. It contains intellectual property from both the Ordnance Survey and the Office for National Statistics.

Use Cases

• Creating national-level thematic maps based on the generalised (20m) boundaries for visual clarity.
• Performing coastal zone analysis using the full-resolution boundaries clipped to the Mean High Water mark.
• Integrating administrative boundaries into web mapping services using the super generalised (200m) version for faster loading.

Strengths

• Provides five distinct geometric resolutions, with file sizes ranging from 168 KB to 29 MB, catering to different use cases.
• Contains boundaries with specific temporal validity, representing the administrative state as of 31 December 2015.

Limitations

• The dataset's columns and exact record count are not specified in the provided metadata.
• There is a conflict in the temporal coverage, as one source mentions boundaries 'as at December 2016', while others specify 31 December 2015.
