- (geopoint-in-closed-polygon? GP GPOLY [INTERSECTS? intersects?-pnp]) => booleanprocedure
Is the (: GP geopoint) in the (: GPOLY (or (vector-of geopoint) (list-of geopoint)))?
INTERSECTS? is a (procedure ((: PI geopoint) (: PJ geopoint) (: LAT real) (: LON real)) => boolean) testing for ray intersection.
Treats an open geopolygon as closed.
