RotatedPole

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

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

Coordinates are measured in projection metres.

Create a RotatedPole CRS.

The class uses proj4 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.

Args:

  • pole_longitude - Pole longitude position, in unrotated degrees.

  • pole_latitude - Pole latitude position, in unrotated degrees.

  • central_rotated_longitude - Longitude rotation about the new

    pole, in degrees.
