[THREDDS #UCC-670485]: interfacing with ArcGIS

The catalog in the above URL (http://usgodae1.usgodae.org/catalog.xml) 
references data that is not being served by a THREDDS Data Server (TDS). You 
aren't able to get to the dataset pages because although the catalog is a valid 
THREDDS XML catalog it doesn't have everything our XML to HTML conversion 
requires to display the dataset pages. Another issue is that the datasets are 
only served via OPeNDAP and are therefore not available through WCS or the 
netCDF subset service.

I don't know of a way around this for the netCDF subset service but there is a 
way around it for WCS. I will double check on the netCDF subset service since 
that is the one you are after.

In the meantime, here is the info on how you could access these datasets 
through WCS. There was a discussion of it just this morning on our THREDDS 
email list. It isn't in our web archive yet so I'll include the relevant text 

> We made an extension of the WCS Dataset URL format to allow the TDS to serve
> remote datasets. Identify the dataset by adding the parameter dataset whose
> value is a URL:
>  http://servername:8080/thredds/wcs?dataset=datasetURL&;

> The URL must be a dataset readable by the NetCDF-Java library, typically an
> OPeNDAP dataset on another server. It must have gridded data, with
> identifiable coordinate systems, etc. For example, an OPeNDAP URL might be
>  http://las.pfeg.noaa.gov/cgi-bin/nph-dods/data/oceanwatch/nrt/gac/AG14day.nc
> This can be served remotely as a WCS dataset with this URL:
> http://servername:8080/thredds/wcs?dataset=http://las.pfeg.noaa.gov/cgi-bin/nph-dods/data/oceanwatch/nrt/gac/AG14day.nc&;
> This is non-standard WCS; we havent emphasized this feature until we have a
> chance to review security implications. The WCS service now if off by
> default, and must explicitly be turned on in threddsConfig.xml, mostly
> because of this feature. We should probably seperately allow users to
> enable/disable "remote WCS access".

I'll let you know what I find out about the netCDF subset service.
