Method Detail

intersection

public static Geometry intersection(Geometry geom0,
                                    Geometry geom1)

Computes the set-theoretic intersection of two Geometrys, using enhanced precision.

Parameters:

geom0 - the first Geometry

geom1 - the second Geometry

Returns:

the Geometry representing the set-theoretic intersection of the input Geometries.

union

public static Geometry union(Geometry geom0,
                             Geometry geom1)

Computes the set-theoretic union of two Geometrys, using enhanced precision.

Parameters:

geom0 - the first Geometry

geom1 - the second Geometry

Returns:

the Geometry representing the set-theoretic union of the input Geometries.

difference

public static Geometry difference(Geometry geom0,
                                  Geometry geom1)

Computes the set-theoretic difference of two Geometrys, using enhanced precision.

Parameters:

geom0 - the first Geometry

geom1 - the second Geometry

Returns:

the Geometry representing the set-theoretic difference of the input Geometries.

symDifference

public static Geometry symDifference(Geometry geom0,
                                     Geometry geom1)

Computes the set-theoretic symmetric difference of two Geometrys, using enhanced precision.

Parameters:

geom0 - the first Geometry

geom1 - the second Geometry

Returns:

the Geometry representing the set-theoretic symmetric difference of the input Geometries.

buffer

public static Geometry buffer(Geometry geom,
                              double distance)

Computes the buffer of a Geometry, using enhanced precision. This method should no longer be necessary, since the buffer algorithm now is highly robust.

Parameters:

geom - the first Geometry

distance - the buffer distance

Returns:

the Geometry representing the buffer of the input Geometry.
