The drop-down menu bar provides access to all displays that are configured for your specific setup of FEWS.

File - Reload configuration (F5)

This menu option allows for the reloading of the configuration. This means that changes to the configuration can be tested without the need to exit and restart the FEWS Explorer. It’s a convenient feature for making adjustments and immediately seeing their effects.

File - Export timeseries

This menu option opens the “Export Time Series” dialog.

This dialog box can be used to filter the selected time series based on view period, module instance, reliability, and status. Once the filter options are selected, the time series that match the given criteria are saved to a file.

When the user selects “unreliable” in the Export Time Series dialog, only export formats that write quality flags are available. These include PI XML files, CSV files with quality flags, and Dutch CSV files with quality flags.

If “unreliable” is not selected in the Export Time Series dialog, then all export formats are available. This is necessary because if unreliable values were exported without quality flags, it would not be possible to identify which values are unreliable in the exported file. In the case of CSV format with quality flags, the complete text of the quality flags (including STATE and DETECTION flags, if they exist) are added to the time series.

The available export formats in the Export Time Series dialog are:

1. PI XML
2. GIN XML
3. CSV, Dutch CSV
4. CSV with Quality Flags
5. Dutch CSV with Quality Flags
6. iBever CSV
7. Hymos Transfer DB 4.50 MDB
8. Hymos Transfer DB 4.03 MDB
9. Menyanthes CSV
10. UM Aquo 2009 XML

File - Dock all undocked windows

Available since 2020.02. Clicking it docks all undocked windows.

File - Temporary import

Available since 2021.02, this feature provides a simple option to temporarily import files in PI XML, NetCDF, or CSV format. This allows you to inspect files without first having to configure a specific import and display.

1D time series (scalar) can be imported using either PI XML or NetCDF. Additionally, the NetCDF format also allows the import of 2D grid data for a single time step. The imported data is not stored in the datastore and will be disconnected when you exit the FEWS Explorer UI.

Please note that NetCDF is a very flexible format, so not every NetCDF file will be imported successfully. FEWS will try to use the NetCDF CF convention to identify location, parameter, and time-related dimensions. For 1-D scalar data, the NETCDF-CF_TIMESERIES import type is assumed, and for 2D grid data, the NETCDF-CF_GRID import type is used.

For the import of CSV format, some configuration is required. A Table Layout needs to be defined to control which columns of the CSV file contain location ID, parameter ID, and date/time information. The table layouts to use are to be configured in the explorer.xml config file.

        <table>
            <dateTimeColumn name="DateTime" pattern="dd-MM-yy HH:mm"/>
            <locationColumn name="Location"/>
            <parameterColumn name="Parameter"/>
            <valueColumn name="Value"/>
        </table>
	</temporaryImportFormat>
</temporaryImportFormats>
<explorerTasks>

For the CSV import, the General CSV parser is utilized. This means it might be possible to copy the table definition from an existing CSV import configuration. Multiple table definitions can be configured, each with a unique name. After this, the user will be prompted to select a table definition to use for the import.

Button bar

The button bar offers quick access to frequently used tools. These tools are plug-ins to the FEWS Explorer. See FEWSExplorer-StatusBar for more information.

In the Button Bar, there is a section further aiding location and parameter selection ()

There is also a button bar in the Data Viewer which allows storing selections you wish to reuse later.
