[thredds] THREDDS & WCS

[Roy Mendelssohn]

Hi John:

I am having problems with WCS as we are testing 3.16.19.  We made the  
changes in the thredds config file, so the service is running, and I  
get a return on the getcapabilities request, but it doesn't contain  
the coverage itself and therefore all other requests break down.  Has  
the info that needs to be in the catalog.xml changed.  It would seem  
so if I compare:

http://www.unidata.ucar.edu/projects/THREDDS/tech/tutorial/ 
ConfigCatalogs.html

with

http://www.unidata.ucar.edu/projects/THREDDS/tech/reference/WCS.html

It is unclear on the last page which that info is required.

Thanks,

-Roy
