<DIV><SPAN class=946073611-11032008><FONT face=Arial size=2>I've been doing a
lot of work using ST_Intersection, ST_Difference, ST_Union etc to cut out
slices of geometries I don't want and slicing up geometries into smaller pieces,
reunioning etc.</FONT></SPAN></DIV>

<DIV><SPAN class=946073611-11032008><FONT face=Arial size=2>I've been running
into a lot of Topological Exceptions of the form directed Edge this and
non-noded that. For the most part I've been able to overcome these by
slicing things smaller or skipping over problem regions (e.g. areas where the
difference is a line or point or something of that sort).</FONT></SPAN></DIV>

<DIV><SPAN class=946073611-11032008><FONT face=Arial size=2>I think a lot of
people have run into the same issues and have gotten frustrated and there
doesn't seem to be a simple solution suggested to overcome
these.</FONT></SPAN></DIV>

<DIV><SPAN class=946073611-11032008><FONT face=Arial size=2>Is there any way we
can change (add overloaded functions or some setting parameter) - that
take additional parameters to simply ignore these errors that says return empty
collection or NULL when a GEOS error is thrown. That way I can
simply ignore these and throw them out of my equation and move
on.</FONT></SPAN></DIV>

<DIV><SPAN class=946073611-11032008><FONT face=Arial size=2>Just a
thought. I'm sure my suggestion is rather simple-minded and I'm sure I'm
missing some reason of why this is not feasible. An explanation of why my
suggestion is stupid at anyrate would be nice.</FONT></SPAN></DIV>
