If you're carrying extra precision in the points of your geometries, you
could try reducing the precision using snapToGrid. Sometimes this
allows union to proceed correctly.

Hello,
"TopologyException: found non-noded intersection."
I keep getting this on some datasets while doing the st_union. I know
some have encountered this before and the suggestion was to find the
incriminating geometry and tidy it up. The problem is that I'm
batching processing these huge quantities of polygons and am unable to
do that.
Any suggestions on how to find a way around this problem?
Many thanks,
Erik.
