Shelley, C, and Burke, H. 2018. Model metadata report for the South Downs teaching model. British Geological Survey Open Report, OR/18/003.

In order for a geological model to be approved for publication or delivery to a client a series of quality assurance checks are carried out. This includes visual examination of the modelled cross-sections to ensure that they match each other at cross-section intersections and fit the borehole and geological map data used. The model calculation is checked to ensure that all units calculate to their full extent within the area of interest and the modelled geological surfaces are checked for artefacts such as spikes and thickness anomalies. The naming convention of the modelled geological units is checked to ensure that recognised entries in the BGS Lexicon of Named Rock Units (http://www.bgs.ac.uk/lexicon/home.html) and the BGS Rock Classification Scheme (http://www.bgs.ac.uk/bgsrcs/) are used as far as possible. Geological models are accompanied by a standard metadata report, such as the London Basin superficial and bedrock Lithoframe 50 model metadata report (Burke et al., 2014), which describes the datasets used in the model and records any geological decisions made during the model construction process.

Any issues found in the QA checking process are recorded and addressed before delivery/publication of the model.
