OSNI Largescale Boundaries: Northern Ireland Local Government Districts (1993)

Northern Ireland's Local Government Districts, as defined in 1993, are represented in this polygon dataset. The data was extracted from the Ordnance Survey of Northern Ireland (OSNI) Largescale database, topologically cleansed, and attributed to create a seamless geographic layer. It is available in multiple geospatial formats for use in desktop and web mapping applications.

Use Cases

• Mapping administrative boundaries for regional planning based on the 1993 district definitions.
• Performing spatial joins for demographic analysis using the topologically cleansed polygon data.
• Creating base maps for web applications using the provided WMS or GeoJSON services.
• Conducting historical comparisons of local government structures using the fixed 1993 snapshot.

Strengths

• Data is topologically cleansed, ensuring geometric consistency for analysis.
• Available in multiple standard geospatial formats (e.g., GeoJSON, Shapefile, WMS).
• Cross-platform presence on EU open data portals indicates official importance and reuse.

Limitations

• Metadata for row count, file size, and specific column attributes is unavailable.
• The dataset represents a historical snapshot from 1993 and may not reflect current administrative boundaries.
• Last update date and original author information are not provided.
