public class MultiPolygon extends GeometryCollection implements Polygonal
Polygons.
As per the OGC SFS specification, the Polygons in a MultiPolygon may not overlap, and may only touch at single points. This allows the topological point-set semantics to be well-defined.

Note that this is a different concept to the dimension of
the vertex Coordinates.
The geometry dimension can never be greater than the coordinate dimension.
For example, a 0-dimensional geometry (e.g. a Point)
may have a coordinate dimension of 3 (X,Y,Z).

GeometryGeometrys are exactly equal,
up to a specified distance tolerance.
Two Geometries are exactly equal within a distance tolerance
if and only if:
GeometryFactory, the SRID,
or the userData fields.
To properly test equality between different geometries,
it is usually necessary to Geometry.normalize() them first.
