Hi Martin, everyone;
The polygons were converted to linestrings in the previous step, and
I've checked...

Are there grid files in the proj directory?

your proj won't have the grids available for conversion.

I noticed this awhile back when we were running some NAD27 to NAD83
conversions but didn't get around to posting until the issue came up in

I have gotten things working under acceptable time constrains with C# by
writing to a file and using the COPY command. My new problem now is that I
have just figured out that the COPY command requires superuser permissions.
Does anyone know if there is any specific permission that I can grant to a
Did you convert your polygons to linestrings? If not, then you are
running the union operation on polygonal geometry. This is the usual
source of topology errors (which are caused by robustness & precision
issues in the underlying linework).

Hi folks;
I posted something a few days back on a noding problem I'm having, and
received no answer. At this point I have more details and I think there
is something seriously wrong.
This is Postgis 1.3.1 and GEOS 3.0.0rc4.

Luis,
I forgot to mention. If you want to output this as KML and save
yourself some work in your script code, you may want to look into using
AsKML instead of AsText function. I think AsKML exists in version 1.2
and up or somewhere around that vicinity.
Hope that helps,

Luis,
I'm not sure if anyone has answered your question, but I didn't see one
so here is my answer.
I think the problem you are having is that you are working in degree
coordinates so when you say buffer 0.1 that actually isn't a constant
radius.
If you can - the best way to fix the problem is t

My worst problem it seems is that I had expected the clear warnings as
described in the README and doc.
I just tried a freshly created DB, initialized with postgis 1.3.1 and
got none of those terrible errors.
So things are able to work. It looks like I will have to 'hard
