RotatedPole

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

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

Coordinates are measured in projection metres.

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.

Parameters:

• pole_longitude (optional) – Pole longitude position, in unrotated degrees. Defaults to 0.
• pole_latitude (optional) – Pole latitude position, in unrotated degrees. Defaults to 0.
• central_rotated_longitude (optional) – Longitude rotation about the new pole, in degrees. Defaults to 0.
• globe (optional) – An optional cartopy.crs.Globe. Defaults to a “WGS84” datum.
