Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

back to the dataset parameter

NOTE: The galeon mailing list is no longer active. The list archives are made available for historical reasons.

I previously removed the dataset parameter to the WCS server, in favor of using the URL path to identify which _local_ dataset to serve.

Now Ive been asked to allow the WCS server to serve remote datasets, eg OPeNDAP datasets on another server. For this, I dont see any other good way to specify the dataset.

Heres a snippet of some preliminary documentation. Comments welcome. You can try this out on motherlode if you want (the example dataset is rather large and slow, but pretty).

-------------------------

A slight extension of the WCS Dataset URL format allows us 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 is

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&;
