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).
