| Direction of this coordinate system axis. In the case of Cartesian projected
coordinates, this is the direction of this coordinate system axis locally.
Examples:
or

or

or
.
Within any set of coordinate system axes, only one of each pair of terms
can be used. For earth-fixed coordinate reference systems, this direction is often
approximate and intended to provide a human interpretable meaning to the axis. When a
geodetic datum is used, the precise directions of the axes may therefore vary slightly
from this approximate direction.
Note that an
org.opengis.referencing.crs.EngineeringCRS often requires
specific descriptions of the directions of its coordinate system axes.
