MultiPolygon(Polygon[])

Constructs a MultiPolygon.

Declaration
public MultiPolygon(Polygon[] polygons)
Parameters
Type Name Description
Polygon[] polygons

The Polygons for this MultiPolygon , or null or an empty array to create the empty point. Elements may be empty Polygons, but not null s. The polygons must conform to the assertions specified in the http://www.opengis.org/techno/specs.htm OpenGIS Simple Features Specification for SQL.
Remarks

For create this Geometry is used a standard GeometryFactory with PrecisionModel == Floating.

Parameters
Type Name Description

HasDimension(Dimension)

Tests whether an atomic geometry or any element of a collection has the specified dimension.

Declaration
public override bool HasDimension(Dimension dim)
Parameters
Type Name Description
Dimension dim

The dimension to test
Returns
Type Description
bool

true if the geometry has or contains an element with the dimension

[Obsolete("Call Geometry.Reverse()")]
public override Geometry Reverse()
Returns
Type Description
Geometry

An MultiPolygon in the reverse order
Overrides
Remarks
