Catalogs can contain references to local files but typically they are generated by a remote data server and contain opendap urls that point back to that server. I'm not sure how the above server is configured but they could look into installing a TDS server: http://www.unidata.ucar.edu/projects/THREDDS/ The IDV can read remote grid files via http if the http server is configured to support byte range requests. It should also handle the basic http authentication that the above server is using. However, there can be performance ramifications with this approach. -Jeff Ticket Details =================== Ticket ID: KOQ-374173 Department: Support IDV Priority: Normal Status: Open
