Fig. 5

Grad-CAM visualizations for CASPIAN and SWIN-Unet. Column titles denote protection scenarios, while rows correspond to models. Heatmaps for each model share a common normalization across scenarios and are overlaid on the Abu Dhabi basemap with shoreline segments delineated by protection status. Darker colors indicate higher saliency. Coastal points are slightly dilated to improve legibility. The figure was created with Python (v3.10.13, https://www.python.org/) using Matplotlib (v3.10.1, https://matplotlib.org/), Contextily (v1.6.2, https://contextily.readthedocs.io/) and Pandas (v2.0.2, https://pandas.pydata.org/).
