Re: remove overlap polygons after union

Hi Richard,

I'm not sure to understand.
What do you mean by "union" ? Is it the union of two table --> select * from table1 union select * from table2 ?
Or "union" for "ST_Union" ?
I think that you're talking about the first proposition.

Now, what do you mean by overlaped ? Do you mean intersect (ST_Intersects) or duplicate (ST_Equals).

Have you used the DISTINCT operator to filter duplicate geometries ?

Have you any error message that you could copy/paste ?

Hope it helps.

Regards,

Gwendall
