com.vividsolutions.jts.simplify.DouglasPeuckerSimplifier

Simplifies a {@link Geometry} using the standard Douglas-Peucker algorithm.Ensures that any polygonal geometries returned are valid. Simple lines are not guaranteed to remain simple after simplification.

Note that in general D-P does not preserve topology - e.g. polygons can be split, collapse to lines or disappear holes can be created or disappear, and lines can cross. To simplify geometry while preserving topology use {@link TopologyPreservingSimplifier}. (However, using D-P is significantly faster). @version 1.7
