Parameters
################################################################################
Required
--------------------------------------------------------------------------------
For the Oblique Cylindrical Equal Area projection a pole of rotation is needed.
The pole can be defined in two ways: By a point and azimuth or by providing to
points that make up the pole.
Point & azimuth
................................................................................
.. option:: +lonc=<value>
Longitude of rotational pole point.
.. option:: +alpha=<value>
Angle of rotational pole.
Two points
................................................................................
.. option:: +lon_1=<value>
Longitude of first point.
.. option:: +lat_1=<value>
Latitude of first point.
.. option:: +lon_2=<value>
Longitude of second point.
.. option:: +lat_2=<value>
Latitude of second point.
Optional
