The dataset is a Soil Corrosivity Map for the U.K. based on the BGS DIGMapGB-PLUS Map. The creation of this dataset involves scoring the Soil Parent Material types for five different attributes that contribute towards the corrosion of underground assets. These are (i) high or low soil pH, (ii) general soil moisture, (iii) the likelihood that soil saturated and undergo periods of anaerobic conditions, (iv) the presence of sulphides and sulphates and (v) the resistivity of the soil parent material. The scoring of each of these parameters was undertaken based on the Cast Iron Pipe Association (CIPA) (now the Ductile Iron Pipe Research Association, DIPRA) rating system. By combining the scores of each parameter a GIS layer has been created that identifies those areas that may provide a corrosive environment to underground cast iron assets. The final map has been classified into three categories signifying: 'GROUND CONDITIONS BENEATH TOPSOIL ARE UNLIKELY TO CAUSE CORROSION OF IRON', 'GROUND CONDITIONS BENEATH TOPSOIL MAY CAUSE CORROSION TO IRON', 'GROUND CONDITIONS BENEATH TOPSOIL ARE LIKELY TO CAUSE CORROSION TO IRON'. The dataset is designed to aid engineers and planners in the management of and maintenance of underground ferrous assets.

The dataset uses the outline of the mining hazard not including coal in Great Britain data but has been re-attributed to reflect the potential affect of underground drainage. It excludes areas of Coal mining as these are covered by the Coal Authority and therefore are not included in this dataset. It has been reattributed from the A-E rating scale indicating the increasing likelihood of an underground mining hazard to a 1-4 scale identifying the likelihood of susceptibility to infiltration. The data was created using expert knowledge to reattribute the original mining area polygons.

This dataset is part of the infiltration SuDS map and infiltration SuDS GeoReport. It has been developed to help inform planning decisions. This dataset shows the permeability of the bedrock for the purposes of determining whether the installation of infiltration sustainable drainage systems is possible. It differs from the permeability indices dataset in the following ways: a score field has been added to polygons, polygons of equal attributes have been merged, a short and detailed description and an advice and layer ID field has been added.

A digital elevation model for the Holocene surface around the area known as Southampton Water. The model was created as part of the Estuaries Reasearch Programme (EMPHASYS)

This dataset classifies bedrock and superficial geologic units according to their aquifer designation - Principal Aquifers, Secondary Aquifers (Secondary A, Secondary B, and Secondary undifferentiated), and Unproductive Strata. The Environment Agency (EA) and Natural Resources Wales (NRW) help to protect groundwater by identifying different types of aquifers ‐ underground layers of water‐bearing, permeable rock or drift deposits from which groundwater can be extracted. The groundwater protection policies for the EA and Natural Resources Wales use aquifer designations that are consistent with the Water Framework Directive. These designations reflect the importance of aquifers in terms of groundwater as a resource (such as a drinking water supply) but also their role in supporting surface water flows and wetland ecosystems. The aquifer designation dataset is jointly owned by the British Geological Survey (BGS) and the Environment Agency (EA). The dataset covers geologic units mapped in England and is derived from BGS Geology 50k (DiGMapGB-50).

BGS identified a requirement to develop methane and carbon dioxide gas emission data holdings in a format that would be suitable both for BGS GeoReports and for value added resellers, such as Landmark, so that information on methane (CH4) and carbon dioxide (CO2) gas emission hazards from natural sources and coal mining can be included in reports for house buyers and developers. Rock strata and unconsolidated deposits can be classified using BGS 1:50,000 scale DiGMapGB data (or 1:250,000 for those sectors of Wales for which 1:50,000 scale geological data is not availabe) according to their susceptibility to gas seepages.

This dataset comprises the raster scans used as source information for capturing DiGMap 1:50000 scale data. The majority were processed under contract in India. Additions have been made. The images are georeferenced.

The data comprises information on the subsurface structure of stratigraphic levels and units in the United Kingdom, detailing depth to and thickness of the units. These result from projects in different parts of the UK performed at different times. Common working scales are 1:50 000 and 1:250 000 with appropriate differences in detail. Much mapping results from interpretation of seismic data, and as a result many of the structural maps are in time rather than depth, although some have been depth converted.

3D geology models have been created for London, Glasgow, Cardiff, Liverpool and Gateshead. Users can create geological cross-sections, synthetic boreholes and horizontal slices through the 3D models. Underpinned by BGS geological data and expertise, the models and reports provide an enhanced understanding of the geological structures and sediments for urban practitioners to inform construction projects, infrastructure design, groundwater assessments and land use planning. These models cover depths from +300 m OD (Ordnance Datum) to -600 m OD. The models which cover Liverpool and London include superficial and bedrock units. The models which cover Glasgow and Cardiff include superficial units on an undifferentiated bedrock base model. The Gateshead Model includes undifferentiated superficial deposits on a bedrock model, but the Superficial Deposits top layer shows the hydro domains map produced for Project Groundwater Northumbria. The models were constructed in the National Geological Model, Urban Geoscience programmes and Project Groundwater Northumbria between 2008-2025 in GSI3D, Groundhog and ASPEN SKUA for deployment to the web viewer. These datasets are managed by the 3D GeoModel project (National Geoscience).

The data is a simplified version of DiGMap for use on the web and for smart applications such as iGeology. Sourced from 1:50000 DiGMapGB-50 Version 6 where available.The attributes therefore include both superficial and bedrock plus their source. The geology is fitted to a relevant topographic base at the time of production. Near full Great Britain coverage is available. The data is available in vector format. BGS licensing terms and conditions apply to external use of the data.
