<div class="moz-cite-prefix">Hi<br>
You're right, but these problemes are occurred after the ST_Union
of few geométies.<br>
Thanks<br>

<div>You can also do the same trick, but reverted.<br>
</div>
This time use buffer (positiv), buffer(negativ).<br>
</div>
This should suppress the error in exterior ring.<br>
<br>
</div>
I have to say this kind of filtering is not ideal to correct
geometry ...<br>
</div>
<div>You would probably need a more serious way of cleaning you
polygon .<br>

<div>You should try st_buildArea, or st_polygonize, as
suggested by Remi. It corrects these kinds of errors.</div>

<div>Thanks for response<br>
The fourth proposition is
correct for external but not
internal lines : ST_Buffer
(ST_Buffer (the_geom), -0.1),
0.1 <br>
<br>
Look <a moz-do-not-send="true"
