[geos-devel] RE: geos-devel Digest, Vol 99, Issue 2

[James.Sewell at lisasoft.com]

Sorry about that,

My version is:

POSTGIS="1.5.2" GEOS="3.2.2-CAPI-1.6.2" PROJ="Rel. 4.7.1, 23 September 2009"
 LIBXML="2.6.26" USE_STATS

I am running on CentOS 32 Bit

The error is:

GEOS union() threw an error!

Which is accompanied by the notice:

NOTICE: TopologyException: found non-noded intersection between LINESTRING (143.861 -36.881, 143.861 -36.881) and LINESTRING (143.861 -36.881, 143.861 -36.881) at 143.861 -36.881

It crashes the command.

All inputs are clean (and are multilinestrings at this stage)

Thanks for the reply, much appreciated.

You didn't include PostGIS and GEOS versions as well:
SELECT postgis_full_version();

That's a NOTICE, shouldn't be a show-stopper.
Did you really check your input with ST_IsValid, btw ?
