CreatePolygonGeometry

Creates a polygon.

Parameters

ExteriorRing

Any of the following geometries can be passed as the ExteriorRing parameter:

·          ILinearRing

·          LinearRing WKT
See “Well-Known Text and Well-Known Binary (WKT and WKB) 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();

interiorRingList

An array of rings of the following types:

·          ILinearRing

·          LinearRing WKT

Return Value

pVal

An IPolygon representing the created polygon
