Interface CartesianCS

All Superinterfaces:

@UML(identifier="CartesianCS",
     specification=ISO_19111)
public interface CartesianCS
extends AffineCS

A 2- or 3-dimensional coordinate system in Euclidean space with orthogonal straight axes. All axes shall have the same length unit of measure.

This type of CS can be used by coordinate reference systems of type GeodeticCRS, ProjectedCRS or EngineeringCRS, potentially in combination with DerivedCRS. The following examples describe some possible set of axes for Cartesian CS used with the above-cited CRS:

Example 1: used with a Projected CRS

Axis name	Abbr.	Direction	Unit
Easting	E	AxisDirection.EAST	metre
Northing	N	AxisDirection.NORTH	metre

Example 2: used with a Geocentric CRS

Axis name	Abbr.	Direction	Unit
Geocentric X	X	AxisDirection.GEOCENTRIC_X	metre
Geocentric Y	Y	AxisDirection.GEOCENTRIC_Y	metre
Geocentric Z	Z	AxisDirection.GEOCENTRIC_Z	metre

Example 3: used with an Engineering CRS for a station fixed to Earth

Axis name	Abbr.	Direction	Unit
Site north	x	AxisDirection.SOUTH_EAST	metre
Site east	y	AxisDirection.SOUTH_WEST	metre

Example 4: used with an Engineering CRS for a moving platform

Axis name	Abbr.	Direction	Unit
Ahead	x	AxisDirection.FORWARD	metre
Right	y	AxisDirection.STARBOARD	metre
Down	z	AxisDirection.DOWN	metre
