I am aware of Robert Picard's excellent GEOINPOLY command (available from SSC) which checks if a point is inside a polygon(s) and if so returns the polygon ID. I understand that this is called a "point-in-polygon" algorithm.
I was wondering if there is any equivalent Stata implementation for analogously checking whether a polygon is fully inside another polygon? Perhaps a ""polygon-in-polygon" algorithm?
