Detailed Description

Computes a point in the interior of an area geometry.

Algorithm

• Find the intersections between the geometry and the horizontal bisector of the area's envelope
• Pick the midpoint of the largest intersection (the intersections will be lines and points)

Note: If a fixed precision model is used, in some cases this method may return a point which does not lie in the interior.
