[postgis-users] Trying to simplify a collection of polygons

[L Bogert-OBrien]

Hi Henri,

Did you try using ST_MULTI and then check the output?  I have had
success with this.

Regards,

Loretta

Hello,
 I have a collection of polygons none of which overlap except perhaps on parts 
of  their outer rings.
I have the impression this cannot be turned into a multipolygon because there is 
overlap.
Is there any way of simplfying this collection to make a normal multipolygon? I 
am thinking of "fusing" the ones that touch.
Thankyou 
Henri
