Geological Mapping

British Gelogical Survey (BGS) is a data-rich organisation with over 400 datasets in its care including: environmental monitoring data, physical collections (borehole core, rocks, minerals and fossils), records and archives. A few of the more popular datasets are available on the Bluesky Mapshop.



Products available:

DiGMapGB-10

Detailed digital geological map data based on BGS's National Grid and County series 1:10 000 and 1:10 560 scale (six-inch to one-mile) maps with updated nomenclature.

Contains:

  • Bedrock geology
  • Superficial deposits
  • Mass movement
  • Artificial ground
  • Linear features

Scale: 1:10,000

Formats: ESRI shp, tab

Coverage: Partial Great Britain


DiGMapGB-50

Generalised digital geological map data based on BGS's New Series 1:50 000 and 1:63 360 scale (one-inch to one-mile) maps with updated nomenclature. Includes a few 1:100 000 scale maps of Orkneys and Hebrides.

Contains:

  • Bedrock geology
  • Superficial deposits
  • Mass movement
  • Artificial ground
  • Linear features

Scale: 1:50,000

Formats: ESRI shp, tab


GeoSure

GeoSure national datasets provide geological information about potential ground movement or subsidence that can help planning decisions. We currently sell all 6 themes in one:

  • collapsible deposits
  • compressible ground
  • landslides
  • running sands
  • shrink swell
  • soluble rocks

Scale: 1:50,000

Formats: ESRI shp, tab


Susceptibility to Groundwater Flooding

BGS has produced the first national hazard dataset for groundwater flooding. Based on geological and hydrogeological information, the digital data can be used to identify areas where geological conditions could enable groundwater flooding to occur and where groundwater may come close to the ground surface.

Scale: 1:50,000

Formats: ESRI shp, tab

NOTE - This data is not shown in the Mapshop viewer.


Aquifer Designation Data

The aquifer designation dataset has been created by the Environment Agency and British Geological Survey and identifies the different aquifers of England and Wales.

From 1 April 2010 the Environment Agency's Groundwater Protection Policy will be using aquifer designations that are consistent with the Water Framework Directive.

These designations reflect the importance of aquifers in terms of groundwater as a resource (drinking water supply) but also their role in supporting surface water flows and wetland ecosystems.

The maps are split into two different type of aquifer designation:

  • Superficial (drift) — permeable unconsolidated (loose) deposits. For example, sands and gravels
  • Bedrock — solid permeable formations e.g. sandstone, chalk and limestone

The maps display the following aquifer designations:

  • Principal aquifers
  • Secondary aquifers (further subdivided into Secondary A, Secondary B, and Secondary Undifferentiated)
  • Unproductive strata

Scale: 1:50,000

Formats: ESRI shp, tab

Coverage: England & Wales


Geological Indicators of Flooding

Geological maps show where all the floodplains and coastal plains in Britain are located and therefore the main areas at greatest risk of flooding; from this information BGS has produced the Geological indicators of flooding dataset.

Scale: 1:50,000

Formats: ESRI shp, tab

NOTE - This data is not shown in the Mapshop viewer.


Infiltration SuDS Map

This dataset is suitable for those involved in the planning and design of sustainable drainage systems (SuDS) and for those who approve SuDS planning applications within local authorities.

Scale: 1:50,000

Formats: ESRI shp, tab


Permeability Data

Permeability data is often used in studies of groundwater and in particular during investigations of pollution or aquifer contamination.

Scale: 1:50,000

Formats: ESRI shp, tab


WellMaster Hydrogeological Database

Digital version of Water Well Archive. Index level data is available for all water boreholes known to the BGS.

Superficial related themes digitised from 1977 first edition Quaternary map (North and South).
