Geological map data

Many of our maps are now available digitally, as vector data and raster images. All of our maps are prepared digitally. Our archive of 'paper-only' maps are being digitised in an ongoing programme.

Digital maps

Geology map of UK Boreholes
The Single Onshore Boreholes Index (SOBI) is an index of over one million records of boreholes, shafts and wells from all forms of drilling and site investigation work held by the BGS.

Geology map of UK DiGMapGB: Digital Geological Map of Great Britain
DiGMapGB has 1:625 000, 1:250 000, 1:50 000, 1:25 000 and 1:10 000 scale datasets for England, Wales and Scotland.

Parent material properties map DiGMap-Plus: value-added geological data
DiGMap-Plus provides a very wide range of value-added geological data and information based on the digital geological map — DiGMapGB-50.

UK offshore geology Offshore geology: DigRock250 and DigSBS250
The 1:250 000 scale offshore geological maps are available digitally as two themes: bedrock geology (DigRock250) and sea bed sediments (DigSBS250).

Sample DigBath250 data DigBath250: bathymetry
Vector attributed digital bathymetry of UK and adjacent European waters including North Sea, English Channel, South West Approaches, Irish Sea and north west Scotland.

Parent material properties map Soil Parent Material Model
A parent material is a soil science name for a weathered rock or deposit from, and within which a soil has formed. The Soil Parent Material Model details the distribution of physiochemical properties of the weathered and unweathered parent materials of the UK.

Superficial thickness Superficial thickness
The Superficial Deposits Thickness Models show the depth of the bedrock surface. This information is critical in civil engineering, the evaluation of groundwater resources and possible water pollution, and in the prediction of surface hazards such as landslides and the collapse of underlying rocks.

The vector data are structured into themes and available in a variety of formats, allowing them to be used in geographical information systems (GIS) where they can be integrated with other types of spatial data.

Data licences

Digital geological map data are available both onshore and offshore at a range of resolutions from small to large scale.
