CreateMultiPolygonGeometry

Creates a geometry made up of multiple polygons.

Parameters

polygonList

An array of the following geometries:

·          ILinearRing

·          IPolygon

·          The LinearRing WKB

·          The LinearRing WKT
See “ Well-KnownText Representation for Geometric Objects” in the “Overview” chapter for background information on WKT and WKB.

·          A Safe Array of Vertices– An array that contains triplets of doubles. Each triplet is composed of an x-coordinate, a y-coordinate, and a height. The height is represented in meters and the x- and y-coordinates are represented in the coordinate system’s units. You can use the ITerrain80 interface to retrieve information about the coordinate system.

Note: In JavaScript, use the VBArray object. E.g.,

var points = geom.Points.ToArray()

var arr = new VBArray(points).toArray();

Return Value

pVal

An IMultiPolygon representing the newly created geometry.

Exceptions

See: HRESULT Return Values for a list of possible values returned by the HRESULT.
