What is Height Map Data?
​

The two products provide a detailed three-dimensional digital terrain model (DTMs) or digital surface model (DSMs) of Great Britain, enabling a full height map of the UK. A digital terrain model primarily defines the ground surface, having removed all protruding features (such as buildings and trees) elevated above the bare earth. A digital surface model includes features such as buildings and trees.

Why use Height Map Data?
​

A true virtual landscape; OS Terrain 5 is the height map 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 use our height maps to quickly understand the impact of flash floods on roads, homes and other major infrastructure. In addition to view shed analysis, traffic noise and drainage. With our height map data, 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 height map data 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
