Package org.locationtech.jts.densify
Class Densifier
java.lang.Object
org.locationtech.jts.densify.Densifier
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
Densifies a geometry using a given distance tolerance, and respecting the input geometry'sPrecisionModel
.- Parameters:
geom
- the geometry to densifydistanceTolerance
- 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
Gets the densified geometry.- Returns:
- the densified geometry
