ELLIPSE1
Anchor Points: This symbol requires one anchor point. This anchor point represents the center of an ellipse and, therefore, the geographic location of that ellipse.
Size/Shape: The size and shape of this symbol is determined by three additional numeric values; A major axis radius, a minor axis radius, and a rotation angle. The radii should be expressed in the appropriate map distance units.
Orientation: The orientation of this symbol is determined by the rotation angle provided, where 0 degrees is east/west and a positive rotation angle rotates the ellipse in a counter-clockwise direction.
