public class MultiPolygon
Models a collection of Polygon
s.
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.

public int getDimension()
Geometry
Note that this is a different concept to the dimension of
the vertex Coordinate
s.
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).

it is usually necessary to Geometry.normalize()
them first.
