Great Britain Electoral Ward Boundaries for December 2015

Four resolution versions of digital vector boundaries for electoral wards and divisions in Great Britain are available, ranging from full resolution to super-generalised 200m. The dataset contains intellectual property rights from both Ordnance Survey and the Office for National Statistics. It is served via ArcGIS REST APIs for INSPIRE View and Feature Download services.

Use Cases

• Electoral mapping and constituency analysis based on the official ward boundaries.
• Geographic Information System (GIS) integration using the provided ArcGIS REST service URLs.
• Creating simplified maps for publication using the generalised (20m) or super-generalised (200m) boundary versions.
• Coastal and maritime boundary analysis using the full-resolution versions clipped to Mean High Water or extending to Mean Low Water.

Strengths

• Provides four distinct boundary resolutions, with specific file sizes listed (e.g., 3 MB for super-generalised, 135 MB for full resolution clipped).
• Contains intellectual property from two authoritative UK sources: Ordnance Survey and the Office for National Statistics.
• Offers direct machine-readable access via documented ArcGIS REST API endpoints for INSPIRE services.

Limitations

• Column names and the total number of features (rows) are not specified in the provided metadata.
• The dataset is static and represents a single snapshot from December 2015, which may not reflect subsequent boundary changes.
• Metadata for 'last updated' (2026-07-08) appears to be a platform timestamp and conflicts with the dataset's reference year of 2015.
