We are excited to announce that our new, free-to-use, BGS Geology Viewer is now available as a replacement. For more information about this change, please visit our FAQ section.

The Geology of Britain viewer is a simple tool, aimed at the general public, which helps you explore the geology where you live.

The Geology of Britain viewer includes:

Geology of Britain update FAQs

What is happening to the the Geology of Britain map viewer?

The Geology of Britain map viewer will be retired on 1 August 2022 and will no longer be available. This includes both the classic 2D Geology of Britain and the 3D version.

Since 2009, BGS has maintained three core map viewer applications: 

  1. Geology of Britain (classic and 3D versions): a web viewer aimed at the general public 
  2. iGeology:  a native mobile app aimed at the general public 
  3. GeoIndex: a web viewer aimed at GeoScience professionals. 

In the years since their launch, there have been a number of advancements in both browser and mobile technology. We believe that now is the correct time to consolidate some of these services, and our resources, into a new bespoke map viewer that provides greater accessibility and is available to a wider audience. As a result, the BGS have made the decision to retire both iGeology and Geology of Britain, replacing them with an intuitive web-based application aimed at the public for both a web and mobile audience. GeoIndex will remain available as our premium map viewer service. 

We will be retiring the map viewer on 1 August 2022. Any changes to this date will be updated on this page. 

Yes! BGS Geology Viewer, a new free-to-use, browser-based, app has launched which offers improved accessibility and larger number of users. The new app is also being designed so that the intended purpose and functionality is distinct from our other services.

For example, BGS GeoIndex is a web tool for professional users who need to access BGS data as part of their business requirements, whilst the new app is designed to make our geological data more accessible to the general public. 

3D cross section data is available via our UK3D dataset on the BGS website. 

Our borehole data is available through a number of BGS sources:
