What OS Terrain 5 provides you with

Ideal for 3D visualisations

OS Terrain 5 is ideal for 3D visualisations. It models significant landscape features including roads, railways, slopes, quarries and lakes, and offers a typical accuracy level greater than 2m RMSE.

A true virtual landscape

OS Terrain 5 is the height data you need to model construction projects within the wider landscape. This helps you give planners an accurate virtual view of your plans and the steps you’re taking to minimise their visual impact on the surrounding area.

Reduce the need for site visits

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.

Harness the elements

OS Terrain 5 helps you 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.
