Class CoordinatePrecisionReducerFilter

java.lang.Object

com.vividsolutions.jts.precision.CoordinatePrecisionReducerFilter

All Implemented Interfaces:

CoordinateSequenceFilter

public class CoordinatePrecisionReducerFilter
extends Object
implements CoordinateSequenceFilter

Reduces the precision of the Coordinates in a CoordinateSequence to match the supplied PrecisionModel. Uses PrecisionModel.makePrecise(double). The input is modified in-place, so it should be cloned beforehand if the original should not be modified.
