Отображение Аляски и Гавайев на карте Картопии

Нанести карты-врезки как части основной карты непросто. Вам нужно будет создать axes для построения каждой карты-вложения и поместить его на figure в нужном месте и в относительном масштабе. Вот рабочий код, с которым можно поэкспериментировать.

# A function that draws inset map, ++
# ===================================
def add_insetmap(axes_extent, map_extent, state_name, facecolor, edgecolor, geometry):
    # create new axes, set its projection
    use_projection = ccrs.Mercator()     # preserve shape well
    #use_projection = ccrs.PlateCarree()   # large distortion in E-W for Alaska
    geodetic = ccrs.Geodetic(globe=ccrs.Globe(datum='WGS84'))
    sub_ax = plt.axes(axes_extent, projection=use_projection)  # normal units
    sub_ax.set_extent(map_extent, geodetic)  # map extents

    # add basic land, coastlines of the map
    # you may comment out if you don't need them
    sub_ax.add_feature(cartopy.feature.LAND)
    sub_ax.coastlines()

    sub_ax.set_title(state_name)

    # add map `geometry` here
    sub_ax.add_geometries([geometry], ccrs.PlateCarree(), \
                          facecolor=facecolor, edgecolor=edgecolor)
    # +++ more features can be added here +++

    # plot box around the map
    extent_box = sgeom.box(map_extent[0], map_extent[2], map_extent[1], map_extent[3])
    sub_ax.add_geometries([extent_box], ccrs.PlateCarree(), color='none', linewidth=0.05)
