Palaeocoastline polyline features delineating former coastlines and shorelines subdivided into those which have been mapped (direct observation) or modelled. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only, 4. Low: Reasonable without any direct evidence
