Syntax

public static class Area

Methods

OfRing(Coordinate[])

Computes the area for a ring.

Declaration

public static double OfRing(Coordinate[] ring)

Parameters

Type	Name	Description
Coordinate[]	ring	The coordinates forming the ring

Returns

Type	Description
Double	The area of the ring

OfRing(CoordinateSequence)

Computes the area for a ring.

Declaration

public static double OfRing(CoordinateSequence ring)

Parameters

Type	Name	Description
CoordinateSequence	ring	The coordinates forming the ring

Returns

Type	Description
Double	The area of the ring

OfRingSigned(Coordinate[])

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.

Declaration

public static double OfRingSigned(Coordinate[] ring)

Parameters

Type	Name	Description
Coordinate[]	ring	The coordinates forming the ring

Returns

Type	Description
Double	The signed area of the ring

OfRingSigned(CoordinateSequence)

Computes the signed area for a ring. The signed area is positive if the

value	meaning
> 0	The ring is oriented clockwise (CW)
< 0	The ring is oriented counter clockwise (CCW)
== 0	The ring is degenerate or flat

ring is oriented CW, negative if the ring is oriented CCW, and zero if the ring is degenerate or flat.

Declaration

public static double OfRingSigned(CoordinateSequence ring)

Parameters

Type	Name	Description
CoordinateSequence	ring	The coordinates forming the ring

Returns

Type	Description
Double	The signed area of the ring
