Yes, there is a way.
First, create a JTS polygon object :
// Creates the geometry factory
GeometryFactory factory = JTSFactoryFinder.getGeometryFactory(null);
// Here is your line string
LineString lineString = YOUR_LINESTRING;
// Creates a linear ring from the linestring (that has to be closed)
LinearRing shell =
factory.createLinearRing(lineString.getCoordinates());
// Creates the polygon
Polygon polygonA = factory.createPolygon(shell, new LinearRing[0]);
// Compares the polygons
boolean toto = polygonA.contains(polygonB);

Hi Everyone
I have a question about geotools. Is there a Way to determine if a
Polygone A contains a Polygone B?
For example.
Polygone A with LineStirng (1 1, 2 3, 4 5, 1 1)
Paygone B which would be inside Polygone A
Now is there a Way to find out, if Poylgone B is inside Polygone A ?
Thanks for an anwser
Mike
