Correction to: Scientific Reports https://doi.org/10.1038/s41598-018-34733-9, published online 05 November 2018 This Article contains errors in Figure 3. The top two images in the first column that show the minimum curvature and shape index after topographic correction, and the top two images in the second column that show the same fields after additional isostatic correction, have all been incompletely plotted. The complete correct Figure 3 appears below as Figure 1.
