Try as I may I cannot figure out this query. I am looking for a collection
contained by a shape.
Help please..

Subject: Re: [Geotools-gt2-users] Best filtering approach needed
You would do better to go the other way, grab the shape of your suburb and
create a query asking for the buildings that fall within that polygon.

SimpleFeature assetShape = it.next();
Point theGeom = (Point) assetShape.getDefaultGeometry();
Filter filter = CQL.toFilter("CONTAINS(the_geom, POINT(" + pt.getX() +
" " + pt.getY() + "))”)
SimpleFeatureCollection sfc = aggfc.subCollection(filter);
} finally {
it.close();
}
I don’t think this is the best way to do this, it seems very slow.
Additionally, I would like to make it shape agnostic, so it also handles
more complex shapes. not just points.
What is the best way to make this generic and faster?
Thanx
