DiGMapGB: onshore Digital Geological Map of Great Britain data

DiGMapGB information downloads

The Digital Geological Map of Great Britain (DiGMapGB) project has made digital geological map data available for much of Great Britain. It ranges from national (small-scale) to detailed (large-scale) resolutions with the availability of the five geological themes tabulated below.

DiGMapGB-625 dataset download

Content and formats

The 1:625 000 scale Digital Geological Map of Great Britain (DiGMapGB-625) dataset covering Great Britain and Northern Ireland is available for free download. Separate bedrock geology and superficial deposits themes, in ESRI® and MapInfo® vector formats, are compressed into zip files that can be downloaded and their contents unzipped to the user’s own machine.

Note: The new (Version.5) Bedrock geology does not necessarily fit well with the older (Version 1) Superficial deposits as they were prepared using different coastlines. The cartographical accuracy is approximately 1 mm which is about 625 m (usually rounded to 1 km) on the ground.
