An example of a real DAR laid over the landscape where it occurred (left panel). The insets are used to depict the geographic location of our Harod valley study area. The plot uses Israeli Transverse Mercator (ITM) projection coordinates. The coordinate time series data is then used to compute the measures listed below, as illustrated using an imaginary trajectory (right panel). The whole-path metrics we used were: the maximum displacement from the green starting point (blue dashed segment), the maximum diameter (maximum distance between any two points; orange dashed segment); the maximum width (sum of the two purple dashed segments, which uses the points furthest on either side of the orange maximum diameter line), and net displacement (the green dotted line which is distance between the green start and red end points), which provides a sense of “DAR openness”
