Hi,<br>
<br>
I am wondering if this is correct to check if polygons are disjoint
when trying to add a new part to a multipolygon.<br>

<br>
Indeed if you try add a new part having a segment in common with an
existing part it won't be ok.<br>
<br>
Also, while trying to slit parts, I cannot use addPart method as it
is, because the parts are not disjoint.<br>
<br>
What do you think?<br>
Should we rather use GEOSOverlaps ?<br>
<br>
Thanks a lot<br>
