@UML(identifier="CS_SphericalCS", specification=ISO_19111) public interface SphericalCS extends CoordinateSystem
A 3-dimensional coordinate system with one distance measured from the origin and two angular coordinates. Not to be confused with anEllipsoidalCS
based on an ellipsoid "degenerated" into a sphere.This type of CS can be used by coordinate reference systems of type
GeocentricCRS
orEngineeringCRS
. 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 AxisDirection.NORTH
degree Spherical longitude Ω AxisDirection.EAST
degree Geocentric radius R AxisDirection.UP
metre Example 2: used with an Engineering CRS Axis name Abbr. Direction Unit Distance r AxisDirection.valueOf("AWAY_FROM")
kilometre Longitude φ AxisDirection.valueOf("COUNTER_CLOCKWISE")
degree Elevation Θ AxisDirection.UP
degree Note: The above example uses two axis directions that are not defined in ISO 19111, but found in ISO 19162 as "awayFrom
" and "counterClockwise
".
