A novel ensemble computational intelligence approach for the spatial prediction of land subsidence susceptibility.

The graphic below is from Arabameri et al. (2020),  “A novel ensemble computational intelligence approach for the spatial prediction of land subsidence susceptibility.” What suggestions do you have for the authors in regards to the figure 8 presented below? How would your suggestions for enhancing their analysis and figure aid with interpretation?
