#4843: GEOS error
-----------------------+--------------------------------
Reporter: ezimanyi | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 3.1.2
Component: postgis | Version: 2.5.x
Resolution: | Keywords: GEOS ST_Intersects
-----------------------+--------------------------------
Comment (by mdavis):
This looks like the usual overlay robustness error. PostGIS 3.0 with GEOS
3.9 introduced major improvements in overlay (ST_Intersection, etc). Can
you try out that version?
If that's not possible, then there are a few hacks to try and get it to
work. One is to snap one or both geometries to a small grid - this can
sometimes change the data just enough to get it to work.
