Re: [thredds] THREDDS & WCS

Hi Roy,

I found WCS GetCapabilities and DescribeCoverage requests were working
but GetCoverage was returning a 404 error with blank message because the
default wcs cachepath in my threddsconfig was not a valid path. Remming
out the default path eg. '/data/tmp/thredds/wcsCache/' or setting a
valid path fixed it.

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: 


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