Overview
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.
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 adds the third dimension to OS MasterMap Topography Layer. You won't find another height product with this level of consistency, currency and detail.
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.
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.
Affordable
With both 5m grid and 5m contours in GML, Esri shape and ASCII grid available for one price, OS Terrain 5 puts the detailed analysis of Great Britain’s landscape within reach.
