    GeodesicEllipseParameter param = new GeodesicEllipseParameter();
    param.AxisDirection = 4 * Math.PI / 3;
    param.Center = new Coordinate2D(-120, 60);
    param.LinearUnit = LinearUnit.Meters;
    param.OutGeometryType = GeometryType.Polyline;
    param.SemiAxis1Length = 6500000;
    param.SemiAxis2Length = 1500000;
    param.VertexCount = 800;
    
    Geometry geometry = GeometryEngine.Instance.GeodesicEllipse(param, SpatialReferences.WGS84);
    // geometry.IsEmpty = false
    
    Polyline polyline = geometry as Polyline;
    // polyline.PointCount = 801
    // polyline.PartCount = 1
