<DIV><FONT face=Arial size=2>I'm using a reference grid of small
polygons.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have been trying to collect concurrent polygons
into one geometry in order to establish the centroid of the region covered. I've
tried a number of operations such as union, contains, accum etc.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I haven't been successful.</FONT></DIV>
