public class MultiPoint extends MultiVertexGeometry implements Serializable
A Multipoint is a collection of points. A multipoint is a one-dimensional geometry object. Multipoints can be used to store a collection of point-based information where the order and individual identity of each point is not an essential characteristic of the point set.
