Hi guys!
I want to cut the field(Multipolygon from the array of polygons,~ about
20000 of polygons) to another field(Multipolygon from shapefile) boundary.
I try the following:
/Geometry shapeMultipolygon = (Geometry) ((SimpleFeatureImpl)
shapeFeature).getDefaultGeometry();
List<Geometry> geometries = new ArrayList<Geometry>();
for (;;) { //start loop with adding Polygon to List
//some code with counting coordinates
Coordinate[] coords = new Coordinate[]{leftUp, rightUp, rightDown,
leftDown, leftUp};
LinearRing tmpRing = geometryFactory.createLinearRing(coords);
geometries.add(geometryFactory.createPolygon(tmpRing, null));
//end loop
}
Geometry geometry = geometryFactory.buildGeometry(geometries);
Geometry intersected = shapeMultipolygon.intersection(geometry);//there is
the TopologyException
/

And I get *com.vividsolutions.jts.geom.TopologyException: no outgoing
dirEdge found* ( http://pastie.org/private/n3yvvxdumv1onptcq7gria full
stacktrace ). Googled a lot about thism but can`t find the solution.
Also, it works ok(no exception) but very long time(about 150 seconds) if I
cut single Polygons one by one.
Is there any other approaches of cutting Multipolygon to another geometry
boundary?
Thank you,
Dmitry.
