BGS DigMap10 data map

BGS Geology 10k and 50k

Generalised digital geological map data based on BGS's New Series 1:50 000 and 1:63 360 scale maps with updated nomenclature.

Product Details

 

Geology maps are the foundation for many other types of earth science related maps and are of potential use to a wide range of customers. 

This product is available at 1:10,000 or 1:50,000 scale

The geological areas (or polygons) are labelled or attributed with a name (based on their lithostratographical, chronostratographical or lithodemic nomenclature) and their composition (rock type or lithology). This information is arranged in up to four themes as available: bedrock geology; superficial deposits; mass movement; and artificial ground. Faults and other linear features are available in a separate theme.

BGS DigMap250 data map

BGS DiGSBS250k

A digital dataset that provides accurate mapping of the distribution of sea-bed sediment types.

Product Details

Sea-bed sediments are mapped offshore, where the most recent deposits commonly form a veneer or superficial layer of unconsolidated material on the seabed. Their distribution and composition is determined using a range of remotely sensed and physical ground truthing data. The sediment divisions on the map are primarily based on particle size analysis (PSA) of both surface sediment samples and the uppermost sediments taken from shallow cores.

Sediments are classified according to the modified Folk scale (Figure 1).The modified Folk diagram and classification used by BGS differs from that created by Folk (1954) in that the boundary between “no gravel” and “slightly gravelly” is changed from trace (0.05%) to 1% weight of particles coarser than -1Ø (2mm). The boundaries between sediment classifications or types are delineated using sample station particle size analyses and descriptions, seafloor topography derived from shallow geophysical data and, where available, multibeam bathymetry, backscatter and side scan sonar profiles.

This dataset can be used in conjunction with other BGS offshore datasets that include DiGRock250k and the DiGHardSubstrate250k datasets.

BGS Geosure map

BGS GeoSure

DigMapGB-50 geology translated into 6 perils layers - swell-shrink, slope instability, dissolution, compressible deposits, collapsible deposits and running sands.

Product Details

The BGS GeoSure datasets identify areas of potential hazard and, therefore, potential natural ground movement, in Great Britain. These data have been produced by BGS geologists and geotechnical specialists and are presented as six GIS data layers relating to the cause of the geohazard:

* Collapsible deposits: Some types of ground can collapse when a load (such as a building or road traffic) is placed on them and when they become saturated. Such collapse may cause damage to overlying property.

* Shrink-swell: Some types of ground can change volume due to variation in moisture. The changing volume can cause ground movement which could potentially affect building foundations, pipes or services.

* Compressible ground: Some types of ground can contain layers of very soft materials like clay or peat. These may compress if loaded by overlying structures, or if the groundwater level changes, potentially resulting in depression of the ground and disturbance of foundations.

* Landslides: Some types of ground may be susceptible to a landslide hazard. Downslope movement of materials, such as a landslide or rockfall may lead to a loss of support and damage to buildings.

* Running sand: Some types of ground can contain loosely packed sandy layers that can become fluidized by water flowing through them. Such sands can 'run', removing support from overlying buildings and causing potential damage.

* Soluble rocks: Some types of ground contain layers of material that can be dissolved by water. This can cause underground cavities to develop. These cavities reduce support to the ground above and can lead to a collapse of overlying material.

BGS Groundwater Flooding map

BGS Groundwater Flooding

Groundwater flood risk types are shown as graded polygons and attributed as either "superficial deposits flooding" or "clearwater flooding".​

Product Details

Groundwater flooding is the emergence of groundwater at the ground surface. It can occur in a variety of geological settings including valleys in areas underlain by Chalk, and in river valleys with thick deposits of alluvium and river gravels. Groundwater flooding happens in response to a combination of already high groundwater levels (usually during mid- or late-winter) and intense or unusually lengthy storm events. Groundwater flooding often lasts much longer than flooding caused by a river over-flowing its banks. It may last many months and can cause significant social and economic disruption to the affected areas.


Data is available in Shapefile or Tab file format. Groundwater flood risk types are shown as polygons and attributed as either "superficial deposits flooding" or "clearwater flooding", and are graded into 5 categories from Very Low to Very High.

BGS Radon map

BGS Radon

This HPA-BGS radon potential dataset is for use in GIS software.

Product Details

The data can be used to answer one of the standard legal enquiries on house purchase in England and Wales (CON29 Standard Enquiry of Local Authority: 3.13 Radon Gas: Location of the Property in a Radon Affected Area). It also provides information on the level of protection required for new dwellings under BR211 (2007) Radon: guidance on protective measures for new buildings.

BGS Borehole data map

BGS Borehole Index

​The Single Onshore Borehole Index (SOBI) is an index of over 1 million records of boreholes, shafts and wells from drilling and site investigation work.​

Product Details

The collection covers onshore and near shore boreholes from Great Britain dating back to at least 1790 and ranging from one to several thousand metres deep. Some 50,000 new records are added each year. The majority of the records contain written descriptions of the ground encountered.

The SOBI index database originated in 1988 from a number of existing tables and from data input from a variety of coding forms. Therefore not all fields in the database are populated and data that should be in some fields may currently form part of the entries in another.

BGS SuDS data map

BGS SuDS

Sustainable Urban Drainage Systems - mapping environmentally beneficial drainage.

Product Details

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.

The dataset gives a preliminary indication of the suitability of the ground for infiltration SuDS. These are drainage systems that allow surface water to infiltrate to the ground, such as soakaways, infiltration basins, infiltration trenches and permeable pavements. The selection and design of an appropriate system depends on the properties of the ground and in particular the following four factors:

  1. the presence of severe constraints that must be considered prior to planning infiltration
  2. the drainage potential of the ground
  3. the potential for ground instability when water is infiltrated
  4. the protection of groundwater quality

The BGS Infiltration SuDS map is based on 15 nationally derived subsurface property datasets, some of which are a result of direct observations, whilst others rely on modelled data.

The dataset is structured using the above four factors, and allows consideration of the subsurface permeability, the depth to groundwater, the presence of geological floodplain deposits, the presence of artificial ground, ground stability (soluble rocks, collapsible ground, compressible ground, running sand, shallow mining, landslide and shrink–swell clays), potential for pollutant attenuation and the Environment Agency's source protection zones.

BGS Permeability data map

BGS Base Data - Permeability

GB-wide 1:50,000 scale hydraulic conductivity (permeability) data.

Product Details

Permeability values indicate the vulnerability of the rock to groundwater pollution from the surface and are a measure of the fastest route by which any pollutant could travel through rocks and enter the underground water resource.

Maximum and minimum permeability indices are given for each geological unit to indicate the range in permeability likely to be encountered and the predominant flow mechanism (fracture or intergranular). Neither of the assigned values takes into account the thickness of either the unsaturated or saturated part of the lithostratigraphical unit. The data is best displayed using GIS, and is available in vector format as ESRI shapefiles and MapInfo TAB files. Please contact us at sales@emapsite.com for further details or a quote.
