Standard Height Data

Our detailed digital terrain and surface models (DTM and DSM) of England and Wales is available as a grid of heighted points and contours, both at 5m intervals (for the DTM) and 25cm intervals (for the DSM).

Whether you’re interested in the terrain, or surface features such as buildings and trees, our data provides detailed height measurements at high accuracy and resolution. Bluesky height data facilitates the understanding, analysis and management of the environment that surrounds us.

Bluesky has an unrivalled National catalogue of height data, which ensures that no matter where your area of interest is, we can provide you with the right information for your application. The data can be provided in a number of formats, enabling utilisation across a variety of software packages.
