如何從通過 cartopyfeature界面導入的數據中提取輪廓線？如果解決方案涉及geoviews.feature或另一個包裝器，那當然可以。例如，我將如何提取cfeature.COASTLINE如下例中繪制的數據？import matplotlib.pyplot as pltimport cartopy.crs as ccrsimport cartopy.feature as cfeatureax = plt.axes(projection=ccrs.PlateCarree())ax.add_feature(cfeature.COASTLINE)plt.show()我很感激你可能有任何提示！FWIW，在basemap，我會這樣做：import mpl_toolkits.basemap as bmimport matplotlib.pyplot as pltm = bm.Basemap(width=2000e3,height=2000e3,            resolution='l',projection='stere',            lat_ts=70,lat_0=70,lon_0=-60.)fig,ax=plt.subplots()coastlines = m.drawcoastlines().get_segments()
