OSNI 50K Boundaries: Northern Ireland Administrative Outline

A mid-scale vector polygon dataset provides the official administrative outline of Northern Ireland. The data is published for open use under the LPS Open Government Data Licence and is available in multiple geospatial formats. Its primary use is for mapping and spatial analysis requiring the national boundary.

Use Cases

• Creating base maps for Northern Ireland based on the official administrative outline.
• Performing spatial joins for regional statistics using the national boundary polygon.
• Integrating the outline into web or desktop mapping applications via the provided Esri REST API endpoint.

Strengths

• Published under a clear open government license (OGL-UK-3.0), facilitating reuse.
• Available on multiple open data platforms (OpenDataNI, EU Open Data), indicating established utility.
• Offered in several standard geospatial formats (SHP, GeoJSON, KML, WMS) for broad compatibility.

Limitations

• Key metadata such as row count, file size, and specific column schema is unavailable across all sources.
• The dataset description is identical and sparse across all platform entries, suggesting limited documentation.
• Future update dates are listed (e.g., 2026-07-08), which may indicate placeholder or incorrect metadata.
