OSNI Mid-Scale Raster: Northern Ireland Base Maps at 1:10,000

A 1:10,000 scale raster map series provides a detailed cartographic base for Northern Ireland. These maps include water bodies, rivers, main roads, town names, and townlands, serving as a foundational layer for spatial analysis. The data is published under the Open Government Licence, facilitating reuse as a background or overlay in desktop and web mapping applications.

Use Cases

• Providing cartographic context for local planning applications based on townland and road features.
• Overlaying thematic data like environmental or demographic information onto a consistent base map.
• Creating regional reference maps for public information or tourism using named towns and water bodies.
• Integrating raster tiles into web mapping services as a background layer for spatial data portals.

Strengths

• Provides a standardized, detailed base map at a consistent 1:10,000 scale for the entire region.
• Includes multiple key geographic features: water bodies, rivers, main roads, town names, and townlands.
• Published under the permissive Open Government Licence, enabling broad commercial and non-commercial reuse.

Limitations

• Metadata is incomplete; specific row counts, file sizes, and last update dates are not provided across sources.
• The dataset is a static raster image, limiting direct querying or analysis of individual features compared to vector data.
• Platform notes indicate the Esri REST API endpoint requires specific GIS software and will not open in a standard web browser.
