Re: [Geoserver-users] Simple WMS query driving me mad!

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 w=
orking fine when I put in the WGS84 coords for the BBOX. So both of these =
requests work:

http://localhost:8080/geoserver1.3RC3/wms=3Fbbox=3D3539209,5803566,3541356,580=
6154&styles=3Dcool&Format=3Dimage/png&request=3DGetMap&layers=3Dlasy:flurstuecke&w=
idth=3D800&height=3D800&srs=3DEPSG:31467

http://localhost:8080/geoserver1.3RC3/wms=3Fbbox=3D9.57,52.36,9.61,52.39&style=
s=3Dcool&Format=3Dimage/png&request=3DGetMap&layers=3Dlasy:flurstuecke&width=3D550&h=
eight=3D250&srs=3DEPSG: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 worki=
ng with the wkt file. Because the way I "generated" the geographic coordin=
ates 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=3F EPSG database=
=3F
If I have those parameters all I need to do is to fill the zero values of =
this: 'TOWGS84[0,0,0,0,0,0,0]' in the *.prj file, right=3F And then I go and=
 create a new feature type and the bbox is generated automatically with th=
e help of the *.prj file=3F

Thanks for helping!

Regards,
Lena
