Short summary
Boundaries on geological maps are drawn by geologists interpreting evidence (boreholes, surface features, etc.) in light of their geological knowledge. Boundaries are therefore uncertain, and this must be quantified so that map users can make sound decisions. In this paper we show how we can find statistical models of the uncertainty of boundary positions by a structured method to elicit the tacit model of uncertainty which experienced field geologists use when interpreting geological maps.
