Regional geological visualisation models

Geological visualisation model areas

A series of geological visualisation (GV) models, covering 14 regional areas of England, Wales and Northern Ireland, provides unique tools for interactive exploration of the diverse geology of the UK to depths of 1.5 km below the surface.

The GV models are constructed from UK3D, the national fence diagram (v2015), combined with the BGS 1:625 000-scale bedrock geological map of the UK. Within each region, the GV model is split into smaller blocks created by the pattern of cross-sections. A description of how the GV models were created is provided in this report.

The models

The extents of the 14 GV models follow the British Regional Geology (Regional Guides) series. Whilst the GV models for England and Northern Ireland show the onshore geology only, the GV models for North and South Wales include offshore areas up to 20 km from the coast. In these areas, a simplified offshore bedrock map has been derived from the BGS 1:250 000-scale marine bedrock map.

The GV models are designed to be interactive, allowing the user to explore them in a number of ways — rotating them, zooming in and out, turning different geological units on and off, and querying key information. A detailed legend provides information on each geological unit in the model, such as the age and type of rock.


We are always striving to improve the accessibility of our GV models, ensuring they are easy to use and understand. Your feedback will help us to develop future resources for presenting and communicating our 3D geological models.

If you would be willing to provide feedback on the models please contact the BGS enquiry service.


The development of the GV models has been financially supported by Radioactive Waste Management (RWM) and forms part of a wider BGS National Programme, funded by a range of stakeholders, to make our science publicly available and accessible to all.
