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.
