shortly after the 1.5.1 release. The renderer is doing a bbox
query against the data to reduce the amount of data that
needs to be loaded, and the bbox reprojection fails to take
into account the middle of the box, but
considers only the perimeter, which lies more or less at the
latitude you mentioned for Antarctica.We fixed it, so you may want to try out a nightly of the 1.5.2 series
here:
http://geo.openplans.org/nightly/1.5.x/If the problem still persists, it means not all code paths
have been taken care of, and I'll need some sample data and
the full request.Cheers

Hi Andrea,
I'm afraid the problem does still exist. I tried the 071007 build.
Here's the request:
http://YOUR-GEOSERVER-HOST/geoserver/wms?bgcolor=0xf2AAAFF&bbox=-2661827
8078423585,-2489793.885787334,2750918.460493497,2321607.9999959785&SLD=
http://milesjordan.com/sld/geos-test.sld&Format=image/png&request=GetMap
&width=600&height=600&SRS=EPSG:3031
The above should show a blue map with yellow dots in opposite corners,
one at -45,-67 and the other at 135,-80, however only the one at -45,-67
appears. I took out the reference to the antarctic coastline layer
because I can't redistribute the data (although it it available from the
Antarctic Digital Database) - it's not needed anyway, as long as the SRS
in the request is set to EPSG:3031.
I noticed 3031 snuck it's way out of the EPSG codes that come with
geoserver releases again, but assume you already have it defined as you
seem to have been doing some work with it!
I see no difference at all with the nightly build - is it possible that
the changes aren't in it yet? Thanks for your help.
Regards,
Miles
