European Electoral Regions: Vector Boundaries for Great Britain

Digital vector boundaries for European Electoral Regions (EER) in Great Britain, representing constituencies for European Parliament elections. The dataset provides multiple geometry resolutions, including full, generalised (20m), super generalised (200m), and ultra generalised (500m) versions, clipped to the Mean High Water coastline or extending to the realm's extent. It contains intellectual property rights from both the Ordnance Survey and the Office for National Statistics.

Use Cases

• Mapping European Parliament constituencies for Great Britain based on the provided vector boundaries.
• Performing spatial analysis of electoral regions using the multiple geometry resolutions (e.g., 20m, 200m, 500m generalisation).
• Integrating electoral boundaries into GIS systems via the provided ArcGIS INSPIRE REST service URLs.
• Creating coastline-clipped or full-extent maps for different cartographic purposes.

Strengths

• Provides five distinct geometry resolutions, with file sizes ranging from 197 KB (ultra generalised) to 31 MB (full resolution clipped).
• Contains boundaries for a specific, documented date (as at 31 December 2016 in the most detailed source).
• Cross-platform presence on uk_data indicates established use and official provenance.

Limitations

• Sources conflict on the effective date, with one describing boundaries as of December 2015 and another as of December 2016.
• Column names and the exact number of regions (rows) are not specified in the provided metadata.
• The 'last updated' platform metadata (2026) appears to be a future date, suggesting potential system errors in timestamp recording.
