Waters, C N, Terrington, R, Cooper, M R, Raine, R B, and Thorpe, S. 2015. The construction of a bedrock geology model for the UK: UK3D_v2015. British Geological Survey Internal Report, OR/15/069.

Data sources consulted and decisions made in section construction were recorded in the specially designed Cross-Section Metadata Recording Database using MsAccess (Figures 16–18). This was formerly known as the GB3D Section Tracker (Mathers et al. 2014a[1] and b[2]). Figure 16 shows the main input form where all metadata details are held. Figure 17 shows a close up example of the diary entries (total over 3752) made for each individual cross-section, and Figure 18 shows part of the extensive list of data sources consulted. The sources were recorded section by section. There are 988 individual sources cited in this database including existing models, cross-sections, structural contour maps, scientific papers and BGS reports. The database also records the QA and approval decisions section by section.

The database was dynamically updated and was utilised by all the participating geologists simultaneously. It can be made available as required as an MsAccess database.
