[postgis-users] GeomUnion returns a Null geometry

[Arnaud Lesauvage]

Hi List,

I have a problem with some geometries.
When I GeomUnion() them, the result is a null geometry.
I tested them for validity and PostGIS tells my they are valid.

Version :
"POSTGIS="1.1.3" GEOS="2.2.2-CAPI-1.1.0" PROJ="Rel. 4.4.9, 29 Oct 
2004" USE_STATS (procs 1.1.0 upgrade)"

I join to this message a csv of the problematic dataset.

Thanks a lot for your help !

Arnaud
