 The `pyproj.Transformer` has the capabilities of performing 2D, 3D, and 4D (time)
 transformations. It can do anything that the PROJ command line programs

 This means that it allows translation between any pair of definable coordinate systems,
 including support for datum transformation.
 
 
 .. warning:: The axis order may be swapped if the source and destination
     CRS's are defined as having the first coordinate component point in a
     northerly direction (See PROJ FAQ on

     You can check the axis order with the `pyproj.CRS` class. If you prefer to
     keep your axis order as always x,y, you can use the `always_xy` option when
     creating the :class:`~pyproj.transformer.Transformer`.
