public static double ofRing(Coordinate[] ring)
Computes the area for a ring.
Parameters:
ring - ring the coordinates forming the ring
Returns:
the area of the ring
public static double ofRing(CoordinateSequence ring)
Computes the area for a ring.
Parameters:
ring - ring the coordinates forming the ring
Returns:
the area of the ring
public static double ofRingSigned(Coordinate[] ring)
Computes the signed area for a ring. The signed area is positive if the ring is oriented CW, negative if the ring is oriented CCW, and zero if the ring is degenerate or flat.
Parameters:
ring - ring the coordinates forming the ring
Returns:
the signed area of the ring
public static double ofRingSigned(CoordinateSequence ring)
Computes the signed area for a ring. The signed area is:
  • positive if the ring is oriented CW
  • negative if the ring is oriented CCW
  • zero if the ring is degenerate or flat
Parameters:
ring - ring the coordinates forming the ring
Returns:
the signed area of the ring
