This dataset is a characterisation of discontinuity types found within rocks and soils in Great Britain. Discontinuities are breaks, fractures or planes of weakness in the rock mass. The dataset includes type, frequency and orientation of discontinuities within rock and soil materials at formation (local to regional) scale. The discontinuities are classified in 3 categories: stratification (bedding planes), foliation (mineral banding) and rock mass description. The dataset aims to facilitate the preliminary research for planning and design of buildings, infrastructure and resource extraction. It forms part of the DiGMap Plus dataset series of GIS layers which describes the engineering properties of materials from the base of pedological soil down to c. 3m depth (ie the uppermost c.2m of geology). These deposits display a variable degree of weathering, but still exhibit core engineering characteristics relating to their lithologies.

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).

BGS LithoFrame models provide 3D geological characterisation for parts of the onshore and offshore UK at a range of scales. They present framework geological interpretation consistent with the stratigraphic framing schemes and scales used in BGS geological maps. Models have been constructed under a range of project activities and include local-scale superficial and bedrock models covering sites and focused study areas, medium-scale superficial and bedrock models covering many urban areas, transport corridors and smaller catchments, and regional-scale bedrock models covering large catchments, district areas, and geological basins. The 3D geological models have been constructed in a period between 2003 and 2018 and is managed by the 3D GeoModel project (National and International Geoscience).
