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
- regional-scale bedrock models covering large catchments, district areas, and geological basins
BGS LithoFrame models are available to licence as gridded stratigraphic horizons. Fault surfaces may also be available for some regional-scale bedrock models. Standard outputs include stratigraphic unit bases supplied in ASCII and ESRI grid formats. Unit tops and thickness, as well as alternative data formats, may be available on request. Grid resolutions are dependent on the model scale and the nature of the input data.
Each model is accompanied by a metadata report describing the input data, model specifications, geological characterisation and limitations. Information on using geological models and model construction is provided here.
