Hi Bingtao, > If I want to implement query for other relations, should I just serialize shape to binary format(e.g. wkb) and fall back to jts?
Yes. There's a lot already there but you'd need to subclass some stuff to add some other predicates. See CompositeSpatialStrategy and ShapeValuesPredicate. You could cast the value, a Shape, to a JtsGeometry (a Spatial4j shape) and then call getGeom() to get the underlying JTS Geometry instance. If you find you need to fork entire classes then feel free to suggest improvements to the extensibility. ~ David On Tue, May 29, 2018 at 10:52 PM Bingtao Yin <ybts...@gmail.com> wrote: > Hi guys, > > Currently only limited spatial relations are supported(e.g. > withins/intersects in prefix tree).
