I'm getting a "found non-noded intersection between LINESTRING ..." error
whenever I call union() on a piece of geometry. How do I fix this? Here is
the error:
Caused by: com.vividsolutions.jts.geom.TopologyException: found non-noded
intersection between LINESTRING ( 362288.81188113254 3579973.0203621145,

The piece of code where the error is being thrown is:
Collection<Geometry> bliss = new ArrayList<Geometry>();
for (FeatureReader<SimpleFeatureType, SimpleFeature> reader = store
.getFeatureReader(); reader.hasNext();) {
SimpleFeature feature = reader.next();
bliss.add((Geometry) feature.getDefaultGeometry());
}
System.out.println("done with bliss");
com.vividsolutions.jts.geom.GeometryFactory factory =
JTSFactoryFinder
.getGeometryFactory(null);
ShapeTemplate blissroadshape = new ShapeTemplate();
blissroadshape.setName("Bliss Roads");
blissroadshape.setDescription("Bliss Roads");
blissroadshape.setShapeType("CTC");
GeometryCollection blissCollection = (GeometryCollection) factory
.buildGeometry(bliss);
System.out.println("one");
Geometry obj = blissCollection.union();
Thanks in advance for your help.
