OS Terrain 5 (T5) Tiles by UK County & Shire | 5m Grid Elevation & Contour Data

OS Terrain 5 (T5) Tiles by UK County & Shire | 5m Grid Elevation & Contour Data

OS Terrain 5 (T5) tiles provide detailed elevation and contour data for Great Britain, supplied as a high-resolution Digital Terrain Model (DTM). This product offers OS Terrain 5 data pre-packaged by UK counties and historic shires, allowing you to access complete regional terrain datasets without selecting individual tiles.

With elevation points spaced at 5 metres and contour lines at 5m intervals, this dataset is ideal for GIS analysis, 3D modelling, planning, and environmental assessment. County-based delivery simplifies workflows by providing ready-to-use terrain data aligned to administrative areas.

What Makes These Tiles Different?

Unlike standard OS Terrain 5 downloads supplied as individual grid tiles, this product groups data into county and shire-based datasets, enabling you to:

  • obtain full county terrain coverage in one purchase
  • avoid managing thousands of individual tiles
  • ensure consistent elevation data across regions
  • streamline GIS, CAD, and modelling workflows

This makes it particularly useful for regional terrain analysis and large-scale planning projects.

What are OS Raster Tiles?

OS Terrain 5 is a mid-resolution digital terrain model that represents the physical shape of the land surface, removing buildings and vegetation to show true ground elevation.

The dataset includes:

elevation data at 5m grid intervals
contour lines at 5m intervals
spot heights and terrain features

Each tile is georeferenced and aligned to the UK National Grid, providing accurate and consistent elevation modelling across Great Britain.

Key Features & Specifications

  • Data type: Digital Terrain Model (DTM)
  • Resolution: 5m grid spacing
  • Contours: 5m interval contour lines
  • Tile size: 5km × 5km
  • Coverage: Great Britain
  • Formats available: GeoTIFF, ASCII Grid, GML, Shapefile
  • Fully georeferenced to the National Grid
  • Supplied as grouped county or shire datasets

This dataset provides accurate elevation modelling with typical vertical accuracy of around 1.5–2.5m depending on terrain.

Coverage by UK Counties & Shires

Terrain data is grouped into county and historic shire areas, enabling efficient access to elevation datasets for:

  • English counties (e.g. Cumbria, Devon, Yorkshire)
  • Scottish historic counties
  • Welsh counties

This approach is ideal for projects requiring complete terrain coverage across administrative regions, such as:

  • infrastructure planning
  • flood risk modelling
  • environmental impact assessments
  • land and estate analysis

Common Uses

OS Terrain 5 data is widely used for:

  • GIS terrain modelling and spatial analysis
  • flood risk and drainage modelling
  • 3D visualisation and landscape modelling
  • planning and development projects
  • environmental and geological studies

It is particularly valuable where accurate elevation data is required to understand the shape and behaviour of the land.

Why Choose County-Based Tile Bundles?

Combining OS Terrain 5 data with county-based delivery provides:

  • faster access to large terrain datasets
  • simplified purchasing and data management
  • reduced GIS setup time
  • consistent elevation coverage across project areas

This is especially useful for professionals working across multiple sites or entire regions.

Delivery & Licensing

  • Fast digital delivery
  • Licensed Ordnance Survey data
  • Supplied in industry-standard GIS formats
  • Suitable for GIS, CAD, and 3D modelling software
