Detailed Description

Coordinate is the lightweight class used to store coordinates.

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.

Coordinate objects 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 DoubleNotANumber. The standard comparison functions will ignore the z-ordinate.
