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
