Hi,

It seems that simplify still creates invalid geometries.

-> psql -f invalid.sql navteq
CREATE TABLE
psql:invalid.sql:5: NOTICE:  Self-intersection
 isvalid | isvalid
---------+---------
 t       | f
(1 row)

I'm using:

POSTGIS="1.1.1CVS" GEOS="2.1.4" PROJ="Rel. 4.4.9, 29 Oct 2004" USE_STATS

AFAICS, this is fixed in JTS 1.7, the attached java test program returns
"true true".

Thanks,
Markus
