A central_longitude value of -160 is recommended for the oceanic view. RotatedPole¶

class cartopy.crs.RotatedPole(pole_longitude=0.0, pole_latitude=90.0, central_rotated_longitude=0.0, globe=None)[source]

A rotated latitude/longitude projected coordinate system with cylindrical topology and projected distance.

Coordinates are measured in projection metres.

The class uses proj to perform an ob_tran operation, using the pole_longitude to set a lon_0 then performing two rotations based on pole_latitude and central_rotated_longitude. This is equivalent to setting the new pole to a location defined by the pole_latitude and pole_longitude values in the GeogCRS defined by globe, then rotating this new CRS about it’s pole using the central_rotated_longitude value.
