The best feature so far is that cartopy fixes one of the most annoying bugs in basemap, the handling of datelines. This release has improved the Python experience a lot by adding an additional Python modules like Fiona, rasterio, cartopy, pandas, geopandas, mappyfile. If I plot 'physical', 'land' it behaves as expected (land is filled), but for 'physical', 'ocean' I would expect the opposite, but instead everything is filled. It does appear that the way cartopy treats the facecolor kwarg to the axes constructor leaves a little to be desired. This is your input. import cartopy. None of these examples make use of xarray's builtin plotting functions, since additional work is most likely needed to extend xarray in order to work correctly.
