OS 50k Raster Tiles by UK County & Shire (1:50,000 Ordnance Survey GeoTIFF Maps)

OS 50k Raster Tiles by UK County & Shire (1:50,000 Ordnance Survey GeoTIFF Maps)

OS 1:50,000 raster tiles are georeferenced GeoTIFF map tiles providing complete coverage of Great Britain at a national mapping scale. This product supplies OS 50k mapping data pre-packaged by UK counties and historic shires, making it easy to obtain full regional coverage without selecting individual tiles.

Based on the Ordnance Survey 1:50,000 colour raster dataset, these tiles are ideal for GIS mapping, strategic planning, and large-area analysis. County-based bundles simplify data acquisition and ensure consistent mapping across administrative regions.

What Makes These Tiles Different?

Unlike standard OS raster tiles supplied individually, this product groups tiles into county and shire-based datasets, allowing you to:

  • download full county coverage in a single purchase
  • avoid selecting multiple 20km tiles manually
  • ensure seamless mapping across large areas
  • streamline workflows for regional and national projects

This makes the dataset particularly suitable for broad-area mapping and multi-region analysis.

What are OS Raster Tiles?

OS 50k raster tiles are digital map images supplied in GeoTIFF format, fully georeferenced to the National Grid. Each tile covers an area of 20km × 20km, providing a wider geographic overview than larger-scale datasets.

They include:

major roads and transport networks
towns and settlements
rivers, lakes, and terrain features
key landscape and topographic information

This dataset is the digital equivalent of the OS Landranger map series, widely used for national and regional mapping.

Key Features & Specifications

  • Scale: 1:50,000
