Metadata report for the Superficial LithoFrame 50 London Basin Model (areas 1-12)

This report describes the methodology and datasets used in constructing the 3D superficial geology LithoFrame 50 resolution model of the London Basin. The London Basin project area was divided into twelve 20 x 20 km tiles, with construction of the first tiles beginning in 2006 and completion of the Areas 1-12 combined model in 2012. This time period coincided with the ongoing development of GSI3D software used to construct the model; therefore several versions of GSI3D were used in the model building process. The model complements the corresponding DigMap GB-50 tiles and consists of 65 modelled superficial and artificial geological units. A Glossary of technical terms used in this report is included at the end of this report.
