Geology of Britain viewer

BGS Map Viewers

As part of our ongoing programme of application upgrades and redevelopment, the Geology of Britain map viewer was retired on 1 August 2022.

If you are looking for an interactive geological map of Great Britain then you may be interested in one of our newer online map viewers listed below:

  • BGS Geology Viewer is a lightweight viewer designed to provide geology enthusiasts and the general public with bedrock and superficial geology maps of Great Britain
  • BGS GeoIndex, which is recommended for professional users and provides access to a wide range of data, including both borehole scans, fault information and interactive 3D models

Geology of Britain update FAQs

The Geology of Britain map viewer was retired on 1 August 2022 and is no longer 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.  BGS made the decision to retire both iGeology and Geology of Britain, replacing them with the BGS Geology Viewer, a lightweight web-based application aimed at the public for general use, and the BGS GeoIndex, a premium map viewer service for professional use. 

BGS host a number of mobile optimised map viewers that offer many of the same features and data as was available in the Geology of Britain viewer.

The BGS Geology Viewer is a free-to-use, lightweight viewer, offering access to bedrock and superficial deposit data across most modern browser-enabled devices.

The BGS GeoIndex is a web tool for professional users who need to access BGS data as part of their business requirements, including borehole records, fault information, and interactive 3D models.

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

Interactive 3D models are also available on the BGS GeoIndex.

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