Hi Lena, Yes I was talking about the bursa wolf parameters issue. And yes you can fill in values for TOWGS84. Actually I am not sure how one can get an exact list of what these parameters should be. However I have noticed that all zero's usually works in most cases so I would try that. I have cc'd Reuben, he is one of the geotools crs experts. He should be able to give us a better answer as to how to obtain the values for these paramters. -Justin Lena Pahl wrote: > Hi Justin! > > I'm using GeoServer 1.3RC3. I don't know if I made clear that I never had that error from the StreamingRenderer Rob was writing about, the WMS is working fine when I put in the WGS84 coords for the BBOX. So both of these requests work: > > http://localhost:8080/geoserver1.3RC3/wms?bbox=3539209,5803566,3541356,5806154&styles=cool&Format=image/png&request=GetMap&layers=lasy:flurstuecke&width=800&height=800&srs=EPSG:31467 > > http://localhost:8080/geoserver1.3RC3/wms?bbox=9.57,52.36,9.61,52.39&styles=cool&Format=image/png&request=GetMap&layers=lasy:flurstuecke&width=550&height=250&srs=EPSG:4326 > > I only had the error 'SRS transformation error - missing Bursa parameters' when creating my feature types. But I would be grateful to get this working with the wkt file. Because the way I "generated" the geographic coordinates was a bit dodgy, I put the file in ArcGIS and let the coords display in WGS84 :-))) > > So, stupid question: where do I get those Bursa params from?
