Function Details |
Determine direction of a polygon defined by a list, sequence, set or tuple of LatLon points.
Example: >>> f = LatLon(45,1), LatLon(45,2), LatLon(46,2), LatLon(46,1) >>> isclockwise(f) # False >>> t = LatLon(45,1), LatLon(46,1), LatLon(46,2), LatLon(45,1) >>> isclockwise(t) # True |
