OSNI 1:1Million Raster Map of Northern Ireland

OSNI Open Data provides a 1:1,000,000 scale raster map image of Northern Ireland, suitable for use as background mapping. The dataset includes place names for towns, cities, and other administrative locations. It is the smallest scale raster product from OSNI, offering a broad overview of the region's geography.

Use Cases

• Creating background map layers for web or desktop GIS applications based on the raster image format.
• Providing geographic context for data visualizations focused on Northern Ireland using the overview scale.
• Referencing town and city locations for regional planning or administrative analysis based on included place names.

Strengths

• Published under the Open Government Licence (OGL-UK-3.0), facilitating reuse.
• Represents an official product from the Ordnance Survey of Northern Ireland (OSNI), indicating authoritative sourcing.
• Available on multiple open data platforms, suggesting established utility and accessibility.

Limitations

• Critical metadata such as file size, row count, author, and last update date are consistently missing or listed as 'unknown' across all sources.
• The dataset is a static raster image, which limits analytical capabilities compared to vector data.
• The 1:1,000,000 scale provides only a broad overview, lacking fine geographic detail.
