Hi there, I have a question on how to reproduce the QGIS "check Geometries" within PostGIS. I'm working with multipolygons layers...
So far i got features with issues using for geometry validity check: - WHERE NOT ST_IsValid(geom) and duplicated nodes with: - WHERE NOT ST_Equals(ST_RemoveRepeatedPoints(geom), geom) In QGIS there's the possibility to set a tolerance value that I have to respect in my check and is set to 1E-3. How can I apply this tolerance level in PostGIS? I looked at ST_QuantizeCoordinates() but it doesn't seems to me doing the right job... Any hints or help is well appreciated...
