The north direction as defined by the magnetic 
north pole at the time of the measurement. The magnetic north pole 
is the direction that a magnet will point to when freely rotating.

The north direction is defined by the coordinate 
grid in the projection coordinate system.

The north direction as defined by the true 
north pole. The true north pole is an average of the actual measured 
north axis, which is the axis of rotation of the earth.

The value is not known. This value should not be used
in normal situations. All reasonable attempts should be made to determine
the appropriate value. Use of this value may result in rejection in some situations.
