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.

Use cases

  • Ideal for 3D visualisations, modelling significant landscape features including roads, railways, slopes, quarries and lakes.
  • Analysing the impact of flash floods on critical infrastructure such as roads, homes and utilities. 
  • Provides an ideal base to enable the third dimension for other data within an appropriate geographical information system (GIS).
