Hi Glenn:
No problem. But we were interested in the general problem, as
there are other datasets which also do not have WCS and which we
would like to add it, rather than trying to get each of them to
add it (Some just have an OPeNDAP server, not a THREDDS
server). Yours allowed me to give Ethan a concrete example so
he could look at the catalogs.
Thanks,
-Roy

Hello Roy-
That particular dataset will be turned on shortly via WCS.
That was an oversight. Nice to have users telling us where we
need stuff! Glenn

Hi Roy,
Looks like you are referencing NCDC catalogs rather than
serving the datasets yourself. So, users would get redirected
to the NCDC server and access the data through the NCDC
server. So, as things stand, NCDC would have to add the WCS
service.
You could point to each NCDC dataset with an NcML wrapper and
actually serve the data from your server rather than
redirecting to NCDC. If you did that, you could add the WCS
service. However, the performance wouldn't be as good as
direct from NCDC.
I'm afraid I don't know about the WCS request for a time
range. So, I'll leave that for others to answer.

Hi Ethan:
I am not certain I follow. To be more specific, look at:
http://oceanwatch.pfeg.noaa.gov/thredds/catalog.html
and scroll down to the datasets " Remote test to Nomads
THREDDS catalog", which is actually on a THREDDS server on an
NCDC computer. They are remotely served through catalogs.
Can we add the WCS service on our end, or will it only work
if NCDC adds the WCS service.
While I have your attention, I have not been able to get a
straight answer if there is a way to send the WCS request to
get a time range, rather than a single time, and if so what
is the syntax for that.
Thanks,

Hi Roy,
If you are actually serving the dataset through your server
(which it sounds like you are since you mention existing
NcML for the dataset) rather than providing a link in your
catalog to the remote server, I believe you can simply add
the WCS service to your TDS configuration catalog and serve
the data via WCS. It shouldn't require any changes to the
NcML, just to the service element in the catalog.
Of course, this depends on the dataset meeting the WCS
server requirements, e.g., evenly spaced grid.
I'm not sure how it would perform. But I'll leave it for
John to respond on that.

Hi:
The question for today is if our TDS is "serving" a dataset
remotely (ie. the remote site has their own TDS and we
just link indirectly to it), can we add a service to our
version that they don't have (just like we can aggregate a
remote dataset that is not aggregated). In particular the
remote dataset only has an OPeNDAP response, but we would
like to be able to respond to both an OPeNDAP and a WCS
response.
If we change our NcML appropriately, will that work?
Thanks in advance,
-Roy
