Set higher regrid_shape when res_factor=1 is set for show_map
As discussed here, the image will be downsampled by default. Because res_factor=1
aims to plot the data in original resolution, we can set it like this:
if res_factor == 1:
regrid_shape = 3000
else:
regrid_shape = None
ax.imshow(image2plot, cmap=palette, interpolation=interpolation, vmin=vmin, vmax=vmax,
regrid_shape=regrid_shape,......
