cartopy.crs.CRS

class cartopy.crs.CRS(proj4_params, globe=None)

Define a Coordinate Reference System using proj.

__init__(proj4_params, globe=None)

Parameters:

• proj4_params (iterable of key-value pairs) – The proj4 parameters required to define the desired CRS. The parameters should not describe the desired elliptic model, instead create an appropriate Globe instance. The proj4_params parameters will override any parameters that the Globe defines.

• globe (Globe instance, optional) – If omitted, the default Globe instance will be created. See Globe for details.
