[udig-devel] wms BoundingBox question

[Tore Halset <halset@xxxxxxxxxxx>]

Hello.

I am working on a OpenMap based WMS server with uDig as the client.  
Over a period of time, I have added some new SRSs to the Capabilities  
for UTMs in different datums and so on. It has worked very well.

This time, I added EPSG:3301. The strange thing is that uDig display  
the orange warning sign when I switch to EPSG:3301 in uDig and the  
error message is something like "could not render". The even stranger  
thing is that uDig never tried to issue a GetMap to the server.

The solution was to add a BoundingBox to the Capabilities like  
"<BoundingBox SRS="EPSG:3301" maxx="800000" maxy="6.7e+06"  
minx="300000" miny="6.3e+06"/>"

Why did uDig need that? I have not added such BoundingBoxs for any  
other SRS that I have added. I have not found a reference in the wms  
standard requiring this BoundingBox. What SRSs need such a BoundingBox?

Regards,
 - Tore.
