Hi,

I need to union adjoining polygons together. I use UnionWithUnionOp()
method in JTS 1.13.
However, sometimes, even if i reduce the geometry precision, it does not
end up with a unique polygon resulting a multi-polygon. In such instances
which method is the best to
avoid creating multi-polygon? I used buffer(0), but it did not work. What
about adding a small +- buffer?

Brian.
