I am using THREDDS 3.6, and like Bjørge Solli, I have been trying out the
example aggregation code. When I initialize the catalog, I get no errors or
warning in the catalog error file (with addition of dataType="Grid" to the
dataset element).
I am then able to select the "WEST-CONUS_4km Aggregation" dataset. However,
when I select the Access: OPENDAP link, I get the error:
Error { code = 1; message = "No data root for
dodsC/satellite/3.9/WEST-CONUS_4km"; };
In one of many attempted workarounds, I tried putting the ncml into its own
file so I could access it through an <access> element. However, it appears
that the <access> element ignores the dataFomat="NcML" attribute and tries to
open the ncml as a netcdf and throws an error.
If anyone has an example xml that uses netcdf aggregation elements please let
me know... I really need this to work!
BTW, my xml is:
