Class Densifier

java.lang.Object

com.vividsolutions.jts.densify.Densifier

public class Densifier
extends java.lang.Object

Densifies a geometry by inserting extra vertices along the line segments in the geometry. The densified geometry contains no line segment which is longer than the given distance tolerance. Densified polygonal geometries are guaranteed to be topologically correct. The coordinates created during densification respect the input geometry's PrecisionModel.

Note: At some future point this class will offer a variety of densification strategies.

Method Detail

densify

public static Geometry densify(Geometry geom,
               double distanceTolerance)

Densifies a geometry using a given distance tolerance, and respecting the input geometry's PrecisionModel.

Parameters:

geom - the geometry to densify

distanceTolerance - the distance tolerance to densify

Returns:

the densified geometry

setDistanceTolerance

public void setDistanceTolerance(double distanceTolerance)

Sets the distance tolerance for the densification. All line segments in the densified geometry will be no longer than the distance tolereance. simplified geometry will be within this distance of the original geometry. The distance tolerance must be positive.

Parameters:

distanceTolerance - the densification tolerance to use

getResultGeometry

public Geometry getResultGeometry()

Gets the densified geometry.

Returns:

the densified geometry
