Class Densifier

java.lang.Object
org.locationtech.jts.densify.Densifier

public class Densifier extends Object
Densifies a Geometry by inserting extra vertices along the line segments contained in the geometry. All segments in the created densified geometry will be no longer than 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.

    • 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
    • densifyPoints

      private static Coordinate[] densifyPoints(Coordinate[] pts, double distanceTolerance, PrecisionModel precModel)
      Densifies a coordinate sequence.
      Parameters:
      pts -
      distanceTolerance -
      Returns:
      the densified coordinate sequence
    • 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 tolerance. 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
