Re: [thredds] Ncml Aggregration

[Jordan Walker <jiwalker@xxxxxxxx>]

I've experimented some with remote aggregation, and it is not possible, 
as far as I can tell, to use the scan element for remote datasets.  You 
have to do something like:

<aggregation ...>
<netcdf location="http://remoteserver/thredds/dodsC/dataset/file1.nc"; />
<netcdf location="http://remoteserver/thredds/dodsC/dataset/file2.nc"; />
</aggregation>

I built these aggregations by parsing the remote THREDDS catalog.xml, 
and it works in concept.  There are possible performance problems with 
this since it is not the normal usage.  The unidata guys might have more 
insight into this.
