org.geotools.geometry.iso.topograph2D.Coordinate
A lightweight class used to store coordinates on the 2-dimensional Cartesian plane. It is distinct from Point, which is a subclass of Geometry . Unlike objects of type Point (which contain additional information such as an envelope, a precision model, and spatial reference system information), a Coordinate only contains ordinate values and accessor methods.
Coordinates are two-dimensional points, with an additional z-ordinate. JTS does not support any operations on the z-ordinate except the basic accessor functions. Constructed coordinates will have a z-ordinate of NaN. The standard comparison functions will ignore the z-ordinate. @source $URL$
