cartopy.crs.RotatedGeodetic

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

Define a rotated latitude/longitude coordinate system with spherical topology and geographical distance.

Coordinates are measured in degrees.

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.

__init__(pole_longitude, pole_latitude, central_rotated_longitude=0.0, globe=None)

Parameters:

• pole_longitude – Pole longitude position, in unrotated degrees.

• pole_latitude – Pole latitude position, in unrotated degrees.

• central_rotated_longitude (optional) – Longitude rotation about the new pole, in degrees. Defaults to 0.

• globe (optional) – A cartopy.crs.Globe. Defaults to a “WGS84” datum.
