Geology Digimap

General

Following an agreement made between the Higher Education Funding Council for England (HEFCE) and the Natural Environment Research Council (NERC), EDINA have developed a subscription service to deliver geological maps and data from the British Geological Survey to Tertiary Education.

Geology Digimap is part of the Digimap Collection of on-line mapping and data delivery facilities. Users can view maps through their web browser, save maps for printing and download the geological map data for use in geographical information systems. There is also access to the Lexicon of Named Rock Units which has details for many of the rocks found on the map.

Geology Digimap, available since January 2007, is free at the point of use for staff and students at subscribing higher and further education institutions and research councils (special conditions apply). Details of how to access the service can be found here.

There are extensive help pages detailing how to use every aspect of the service and the data in your own GIS or CAD software:

The Digimap Blog, YouTube Channel, Facebook Page and Twitter Account all provide additional support for the service.

        

Data

Geology Digimap contains map data at scales ranging from 1:625,000 to 1:50,000 available for making maps online or for download. For a full list and detailed description see the Products Available page.

Complete coverage of Great Britain is available for all the products listed, except for a few areas of Wales at the most detailed level, at the moment. It is expected that the range of datasets that are available through Geology Digimap will increase over time.

If you want to know what you can and can't do with the maps and data from Digimap please read the Copyright Terms and Conditions. There is a set of Licence FAQs if you need more clarification about what you intend to do with the maps or data.
