responded - Melissa Blackwell, Ashley Simmonds, Katrin, Warren Vick, Peter
Horsbøll Møller and Jamie Justham. It amazes me how much some of you put
into this list.

Hi all,
Is there any way to identify, by a query or other straightforward process,
all regions that have a hole or holes in them? The ObjectInfo function will

Hi all,
Is there any way to identify, by a query or other straightforward process,
all regions that have a hole or holes in them? The ObjectInfo function will
enable multi-polygon regions to be identified, but I can't see that it will

TIA,
