Examples of com.vividsolutions.jts.geom.Geometry.union()

com.vividsolutions.jts.geom.Geometry.union()
Computes a Geometry representing all the points in this Geometry and other. @param other the Geometry with which to compute the union @return a set combining the points of this Geometry andthe points of other @throws TopologyException if a robustness error occurs @throws IllegalArgumentException if either input is a non-empty GeometryCollection

        Feature feature = (Feature) features.get(i);
        union = union.union(feature.getGeometry());
