Interesting, well that may be your issue? 4326 is a two-dimensional SRS, please make use of a three dimensional SRS.
What does the SRID number say in PostGIS? It should be baked into each geometry (and should not work if if set to 4326). I guess it could be that you have a two dimensional XY geometry, with two measures depends how you have encoded it. -= Jody On Tue, Dec 6, 2022 at 12:35 AM Hans Yperman <hans.yper...@vliz.be> wrote: > Thanks for your help, Jody > > > > The data is indeed XYZM, and the srid is 4326. > > > > > > For reference: This is the full constraint on the column: > > constraint enforce_dims_the_geom > check (st_ndims(the_geom) = 4) > constraint enforce_geotype_the_geom > check ((geometrytype(the_geom) = 'MULTIPOLYGON'::text) OR (the_geom IS > NULL)) > constraint enforce_srid_the_geom > check (st_srid(the_geom) = 4326) > > > > This is a small fragment of the data (note I get the crash even on an > empty table): > > > > SELECT *st_astext*(the_geom) FROM the_relevant_table LIMIT 1 > > > > MULTIPOLYGON ZM ((( .. numbers ..))) > > > > Hans > > > > > > *Hans Yperman* > > Department IT > > > <https://www.google.com/maps/search/Jacobsenstraat+1+%0D%0A+8400+Oostende,+Belgi%C3%AB?entry=gmail&source=g> > > *Vlaams Instituut voor de Zee vzw* > > InnovOcean Campus, Jacobsenstraat 1 > <https://www.google.com/maps/search/Jacobsenstraat+1+%0D%0A+8400+Oostende,+Belgi%C3%AB?entry=gmail&source=g> > > 8400 Oostende, België > <https://www.google.com/maps/search/Jacobsenstraat+1+%0D%0A+8400+Oostende,+Belgi%C3%AB?entry=gmail&source=g> > > > > ☎+32 (0) 59 33 61 13 > > 📧 hans.yper...@vliz.be > > *www.vliz.be* <http://www.vliz.be> > > > > > > *From:* Jody Garnett <jody.garn...@gmail.com> > *Sent:* maandag 5 december 2022 14:45 > *To:* Hans Yperman <hans.yper...@vliz.be> > *Cc:* Geoserver-users <geoserver-users@lists.sourceforge.net> > *Subject:* Re: [Geoserver-users] Output dimension must be 2 or 3 > > > > We added support for dimensions and measures in that timeframe.
