@UML(identifier="CS_SphericalCS", specification=ISO_19111) public interface SphericalCS extends CoordinateSystemA 3-dimensional coordinate system with one distance measured from the origin and two angular ordinates. Not to be confused with an
EllipsoidalCSbased on an ellipsoid "degenerated" into a sphere.
This type of CS can be used by coordinate reference systems of type
EngineeringCRS. The following examples describe some possible set of axes for spherical CS used with the above-cited CRS:
Example 1: used with a Geocentric CRS Axis name Abbr. Direction Unit Spherical latitude Θ
degree Spherical longitude Ω
degree Geocentric radius R
metre Example 2: used with an Engineering CRS Axis name Abbr. Direction Unit Distance r
kilometre Longitude φ
degree Elevation Θ
degreeNote: The above example uses two axis directions that are not defined in ISO 19111, but found in ISO 19162 as "
awayFrom" and "
