addPoint ( Coordinate $point )
contains ( Coordinate $point ) : boolean	Determine if given point is contained inside the polygon. Uses the PNPOLY algorithm by W. Randolph Franklin. Therfore some edge cases may not give the expected results, e. g. if the point resides on the polygon boundary.
containsGeometry ( location\GeometryInterface $geometry ) : boolean	Determine if given geometry is contained inside the polygon. This is assumed to be true, if each point of the geometry is inside the polygon.
format ( Location\Formatter\Polygon\FormatterInterface $formatter ) : mixed
getArea ( ) : float	Calculates the polygon area.
getLats ( ) : float[]	Return all polygon point's latitudes.
