    • concaveness

      public static double concaveness(Geometry geom)
      A concaveness measure defined in terms of the perimeter length relative to the convex hull perimeter. 
      C = ( P(geom) - P(CH) ) / P(CH)
      Concaveness values are >= 0. A convex polygon has C = 0. A higher concaveness indicates a more concave polygon.

      Originally defined by Park invalid input: '&' Oh, 2012.

      Parameters:
      geom - a polygonal geometry
      Returns:
      the concaveness measure of the geometry
