OSNI 50K Boundaries: Northern Ireland Wards (1993)

Northern Ireland's 1993 Ward boundaries are defined in this mid-scale vector polygon dataset. It is published for open data use under the LPS Open Government Data Licence. The data is suitable for desktop and web mapping applications, though direct browser access to the Esri REST API is not supported.

Use Cases

• Historical boundary analysis based on the 1993 administrative delineation.
• Spatial joins for demographic or socio-economic data using Ward polygons.
• Creating base maps for regional planning and public service delivery.
• Integrating administrative boundaries into desktop GIS or web mapping applications.

Strengths

• Provides a specific, historical administrative snapshot from 1993.
• Cross-platform availability on uk_data and eu_open_data indicates established use.
• Available in multiple geospatial formats including ESRI SHAPE, GEOJSON, and KML.

Limitations

• Metadata is incomplete; column names, row counts, and precise data size are unknown.
• The dataset's age (1993) limits its utility for current administrative analysis without updates.
• A future update date (2026-07-08) listed on uk_data is inconsistent with the dataset's historical nature.
