Introduction

Currently, the only graphical user interface to access the Deltares Open Archive is via the Delft-FEWS GUI. In addition, data can be approached via the Geonetwork web client of via THREDDS web server.

...

This user guide is derived from the HyFS application as used at the Bureau of Meteorology.

Archived data

In the Delft-FEWS application, scheduled and manual archive workflows can take care of archiving the data (sets) from the database. The scheduled archive workflow is generally run once a day and will generally archive the following type of data:

...

Note: External data which is archived elsewhere should in general not be archived within the context of the Delft-FEWS application.

Events

Within Forecasting organisations, events are situations that can be distinguished from business as ususal as something special or interesting is happening, e.g. a flood, drought or calamity. Generally the operations during an event is hectic and no one wants to spent time on data archiving. however, after the event the archived data may be crucial for legal inquiries, performance assessment, or model calibration or to use as input for training. Therefore, the concept of Event has been introduced to label a period of interest for a certain area, such that one easily can find this data back.

...

Finally, events can play a crucial role in the data management of the archive. Data labelled for a specific type of event may be help longer in the archive compared to data not labelled for an event. E.g. Numerical Weather Predictions may be removed quickly, except for those external forecast that are part of a Flood Watch or training event.

Archive display

All data that is archived can be accessed and downloaded through the Delft-FEWS archive display. The archive display can be started from the Delft-FEWS Explorer from the Tools menu.

...

If you want to use the data within a different context, you may also copy the data to the normal Import folders, and setup a normal timeSeriesImport run module with idmapping to bring the data into the Delft-FEWS stand alone application registered under your timeSeriesImport run module.

Archive Database

A mongo database plugin can be added to the archives to store scalar data. This tab is only available if you added a <archiveDatabase> to your config. To search for or download data from the database, different filters can (or must be used). The list of areas available is loaded from the configuration.
