OSNI 50K Transport Points: Roads and Railways of Northern Ireland

OSNI 1:50,000 transport layer is a vector dataset providing information on all motorways, A, B, C class, and minor roads in Northern Ireland. The dataset includes road names and railways, published by the Government Digital Service under an Open Government License. It is available in multiple geospatial formats including KML, GeoJSON, and ESRI Shapefile.

Use Cases

• Mapping road networks based on the described motorway and road class hierarchy.
• Analyzing transportation infrastructure density based on the vector layer of all roads.
• Geocoding or address matching based on the included road names.
• Integrating railway data with road networks for multimodal transport planning.

Strengths

• Covers all road classifications (motorways, A, B, C, and minor roads) for a complete region.
• Provides vector data at a standardized 1:50,000 scale.
• Available in multiple interoperable geospatial formats (KML, GeoJSON, ESRI Shapefile, CSV).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment.
