European Electoral Regions: Vector Boundaries for Great Britain

Digital vector boundaries for European Electoral Regions in Great Britain as of December 2016. The dataset provides five boundary versions, including full-resolution and multiple generalized versions clipped to the coastline. It contains intellectual property rights from both the Ordnance Survey and the Office for National Statistics.

Use Cases

• Electoral mapping based on high-resolution vector boundaries.
• Spatial analysis of voter demographics using region geometries.
• Creating generalized maps for web visualization using the 20m, 200m, or 500m simplified boundaries.
• Integrating administrative boundaries into GIS systems via the provided ArcGIS REST services.

Strengths

• Provides five distinct boundary versions for different use cases, from full resolution (26-31 MB) to ultra-generalized (197 KB).
• Contains intellectual property from authoritative UK sources: Ordnance Survey and the Office for National Statistics.
• Available via multiple formats and an ArcGIS INSPIRE Feature Download Service for programmatic access.

Limitations

• Metadata is incomplete; specific column names, row counts, and exact file sizes for some entries are unknown.
• There is a conflict in the temporal reference; sources cite boundaries for both December 2015 and December 2016.
• The dataset is static and does not reflect boundary changes after the referenced date.
