[postgis-devel] bug in simplify a polygon

[strk at refractions.net]

I've tried running your query on 0.8.2 and the bug is not there.

Note that the simplify code have been patched:

 * Revision 1.3  2004/04/27 13:50:59  strk
 * Fixed bug in simplify() that was using the square of the given tolerance.

The patch has been first included in 0.8.2.

Your 0.01 tolerance were squared to 0.0001, but this does really
not explain your problems, as the effects of this should be
simplifying much less!

If you're not using 0.8.2 try upgrading (0.9 is out!)
Otherwise let me know.

Thanks.
