Northern Ireland Electoral Ward Boundaries from 1993

OSNI provides a polygon dataset of Standard Electoral Wards set in 1993. The data has been extracted from the OSNI Largescale database, topologically cleansed, and attributed to create a seamless dataset. This service is published for OpenData by the Government Digital Service.

Use Cases

• Create thematic maps for demographic analysis based on 1993 electoral ward boundaries.
• Perform spatial joins for business planning using the topologically cleansed polygon dataset.
• Visualize administrative regions for public information services based on the generalized boundary data.

Strengths

• Dataset is topologically cleansed to create a seamless polygon layer.
• Data is provided in multiple common geospatial formats including ESRI SHAPE and GEOJSON.

Limitations

• Boundaries have been generalized, reducing vertex count and deviating from official detailed lines.
• Row count and last update date are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
