National Assembly for Wales Electoral Regions: Vector Boundaries

December 2015 and December 2016 boundaries for the National Assembly for Wales Electoral Regions. The dataset provides digital vector boundaries in multiple resolutions, including full extent, coastline-clipped, and several generalised versions (20m, 200m, 500m). It is intended for mapping and geographic analysis of Welsh electoral geography.

Use Cases

• Electoral mapping based on vector boundary geometries.
• Spatial analysis of regions using coastline-clipped or full-extent boundaries.
• Creating generalised maps for visualization using the 20m, 200m, or 500m resolution files.
• Integrating Welsh electoral geography into larger UK-wide administrative datasets.

Strengths

• Provides multiple geometric resolutions, from full detail (2-3 MB files) to ultra-generalised (23 KB file).
• Contains intellectual property from both Ordnance Survey and the Office for National Statistics, indicating authoritative sourcing.
• Available via standardized INSPIRE-compliant ArcGIS REST services for programmatic access.

Limitations

• Key metadata such as row count, specific column names, and author are not provided.
• There is a conflict in the temporal coverage, with sources referencing boundaries from both December 2015 and December 2016.
• The 'last updated' metadata fields show future dates (2026), which may indicate system errors or placeholder values.
