Frank,<br>
I've reviewed your Geos Overview. It looks pretty good. I've made a
few changes, nothing too major.<br>
<br>
One thing I wish to check is the "Implemented Standards", which I've
introduced.<br>
Are we right to add the following:<br>
<br>
Implemented Standards<br>
<br>
OpenGIS Simple Features for SQL spatial predicate functions and
spatial operators<br>
<br>
<br>
You can see all my suggested changes here:<br>

Frank, do you have suggestions for a GEOS image?<br>

I have prepared a preliminary geos overview and checked it into
the
<br>
directory with the other overviews. There is no screen snapshot
for
<br>
GEOS.
<br>
<br>
<br>
I tried the online RST previewer but it was pretty limited so
hopefully
<br>
things will look ok when processed for real.
<br>
<br>
I have not linked the document in any index yet.
<br>
<br>
Best regards,
