OS Terrain 5 is a detailed digital terrain model (DTM) of Great Britain, available as a grid of heighted points and contours, both at five-metre intervals. Both OS Terrain 5 and OS Terrain 50, provide detailed three-dimensional digital terrain models (DTMs) of Great Britain. A DTM primarily defines the ground surface, having removed all protruding features (such as buildings and trees) elevated above the bare earth.

OS Terrain 5 is published as both grid and contour data, each in a variety of formats. Both data types are created from the same source data and are supplied as 5km-by-5km tiles.
OS Terrain 5 is ideal for 3D visualisations. It models significant landscape features including roads, railways, slopes, quarries and lakes – offering a typical accuracy level greater than 2m RMSE.
OS Terrain 5 provides the height data needed to model construction projects within the wider landscape. This helps give planners an accurate virtual view of plans and the steps you’re taking to minimise their visual impact on the surrounding area.
You can quickly understand the impact of flash floods on roads, homes and other major infrastructure. You're able to assess the lie of the land on-screen, reducing the need for time-consuming site visits.
OS Terrain 5 helps you to analyse wind speed and signal propagation. This is important when siting wind turbines, best located in exposed upland areas to maximise their power output, and mobile phone masts, which serve ever more data-hungry users.
You can try out a sample of OS Terrain 5 data for evaluation and testing through the product page here. Alternatively, you can try out the full product by applying for a Data Exploration license.
