Roy,
I was able to get an image using the following query. The image looks fine
although I am not sure how many elements along time, elevation, x, and y are
included in the image because I don't know how to save it into a file (the
image was displayed in my browser).

Hi:
We are having trouble with getting WCS services working with TDS 3.10
serving aggregate data. If you look at the base URL:
http://oceanwatch.pfeg.noaa.gov:8081/thredds/catalog.html
and look at any of the datasets under "Aggregation Satellite
Datasets" those are the datasets we are talking about. They are all
time aggregated
Some info:
1. The OpeNDAP part of this works fine, including the aggregation.
2. I am just learning the WCS syntax, so I may be making errors, but I
get do a successful GetCapabilities, I can do a successful
DescribeCoverage but I fail when I try to actually get the data - I get a
"null" returned (this is using curl with the appropriate http commands)
3. I have tried the same things with Map Browser with the same results.
So, we besides possible help, we have some questions:
1. Is there an example site where aggregate data is being served using
TDS 3.10 and the WCS service works? Could we be pointed to that? Even
more, could we get the NcML and catalog xml files so we can see how they
are set up.
2. Has Map Browser been tried with an aggregated dataset being served by
TDS and shown to work?
3. As I am not certain that my GetCoverage request was correct, could
someone who knows what they are doing send me a properly formed one for
any one of the datasets above (or the same test and and let me know the
results)
We would really like to try and get this to work and are stumped as to the
problem. Once working,w e can add these to the Galeon project.
