GeometryEngineEllipseGeodesic Method

The function returns a piecewise approximation of a geodesic ellipse (or geodesic circle, if semiAxis1Length = semiAxis2Length). Constructs a geodesic ellipse centered on the specified point. If this method is used to generate a polygon or a polyline, the result may have more than one path, depending on the size of the ellipse and its position relative to the horizon of the coordinate system. When the method generates a polyline or a multipoint, the result vertices lie on the boundary of the ellipse. When a polygon is generated, the interior of the polygon is the interior of the ellipse, however the boundary of the polygon may contain segments from the spatial reference horizon, or from the GCS extent.

Type: Esri.ArcGISRuntime.GeometryGeodesicEllipseParameters
The geodesic ellipse parameter that describes how to create the geodesic ellipse.

Return Value

Type: Geometry
The geometry that contains the geodesic ellipse.
If the smaller axis is zero, the ellipse will degenerate to a line segment, a point, or an empty geometry (depending on the larger axis and output type). Otherwise, if MaxPointCount < 10, the number of vertices will default to 10. Supported output geometry types are Polygon, Polyline and Multipoint.
