*2.1. Cases*

To better evaluate and compare the results, our previous study had six classes in the scene [13]. However, it was found that Himalayan areas with shadows and melting ice are quite challenging in the task. Hence, the authors introduced two more cases that will help better understand the results. Figure 1 shows the Landsat 8 scene in pansharpened natural color composite image with water and non-water reference dataset and cases.
