National Assembly for Wales Constituency Boundaries, 2016 Super Generalised Clipped

Office for National Statistics provides digital vector boundaries for National Assembly for Wales Constituencies as of 31 December 2016. The dataset includes four boundary resolutions: full extent of the realm, full resolution clipped to the coastline, and generalised (20m) and super generalised (200m) versions clipped to the coastline. It contains Ordnance Survey and ONS intellectual property rights and is available via ArcGIS REST services.

Use Cases

• Map electoral constituencies for Wales based on the super generalised (200m) boundaries mentioned in the description.
• Conduct spatial analysis of Welsh political units using the coastline-clipped vector data.
• Integrate administrative boundaries into a GIS platform using the provided ArcGIS REST service URLs.
• Compare different boundary generalisation levels (20m vs 200m) for cartographic or computational purposes.

Strengths

• Provides four specific boundary resolutions with stated file sizes (e.g., 87 KB for super generalised).
• Contains a specific snapshot date (31 December 2016) for the constituency boundaries.
• Includes direct access to authoritative ArcGIS REST services for viewing and download.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
