Overview

This import can be used to import the latest (grid) forecast from the netcdf storage from the Deltares Open Archive.

It might be possible to use this import for any THREDDS-server.  However the parsers used in this import are the parsers used in the Netcdf storage.

These parsers are quite generic so it is very likely that they are capable of parsing the content of an external THREDDS server, but it is not guaranteed!

The import will determine which file contains the latest forecast by using a filepattern.

By applying the file pattern to the file name the import can determine the date/time of the file. The file with the latest date/time will be imported. Files which do not have a matching file pattern will be ignored.

Several properties are mandatory when using this import:

• dataServerURL, The URL of the root of the HTTP-server of THREDDS. 
• relativePath. The relativePath of the THREDDS directory compared to the root of the THREDDS-server. It is possible to include a date/time pattern in the relativePath. Note that the parts which are part of the date/time pattern should be in between quotes (').
• filePattern. The file pattern which will be used to determine the date/time from the file name.
• importAsReferences. This properties is a boolean. It indicates if the grid data should be imported by references or not. The default is no.

Note that you have to configure two URL! The first one is the URL of the THREDDS catalogue. This URL is configured in the serverURL element.

The second URL is the URL of the HTTP-server of THREDDS. This URL is configured in the properties section as the property dataServerURL.
