How to Work in This Dialog

Selecting the structure of the time series browser tree

You can determine the structure of the time series browser tree by selecting the following anchors in the drop-down list box above the time series browser:

▪Parameters

▪Collection list

▪Station

▪Station group (usage)

▪Station type

▪Transaction

▪Filter

You can make this selection in the drop-down list box above the time series browser tree.

Depending on the selection of the structure of the time series browser tree, the elements are arranged in the time series browser tree.

Search active stations in selected time range

A special feature of this time series browser tree configuration is the function "Search active stations in selected time range". This function is available to quickly record the stations that are or were active in a selected period.

▪In the upper part of the dialog, use the two calendar functions to select date limits for an entry range.

▪Now select the "Search active stations in selected time range" function in the context menu of the browser tree.

▪The system marks the stations (or the time series contained) that do not contain data for the specified date range with a red cross.

▪No time series are available in this station in the selected time range.

Time Series Selection

▪If you want to select time series,

▪double-click successively on the desired time series in the time series browser tree in the left-hand section of the time series browser.

Time series selected in this way are taken over in the time series selection window (in the right-hand section of the time series browser).

Entering the time range

Entering the time range to view the selected time series can be done in different ways.

You can

▪select the date directly in the date field using the calendar function,

▪or set it efficiently in the Most recent n days from today box as a relative time range without editing the date boxes,

▪or double-click on a time series in the time series browser selection window to select the time range for which measured values of the selected time series are available in the database.

Creating a new folder in the user time series collection list

With this function you can add as many additional collection lists as you like to the existing ones.

▪To create a new folder, click on the parent folder in the tree structure into which the new folder is to be integrated.

▪Open the context menu with the right mouse button to select the New folder function.

▪Select an identifier for the new folder and confirm with [OK].

Rename existing folder or collection list

▪To do this, click on the entry in the time series browser tree that you want to change.

▪Open the context menu of the tree entry by activating the right mouse button.

▪Now select the Rename folder/collection list entry.

▪Change the entry directly in the name field within the tree structure.

▪By activating the [Return] key, you confirm your entry.

Deleting a folder or a collection list

Note:

You can only delete a folder if it no longer contains another (sub)folder.

Should you nevertheless have made such a selection, you will be informed by an error message.

▪Select the desired subfolder and open the context menu with the right mouse button.

▪Select the Delete folder/collection list function.

▪Now confirm the dialog with [OK].

Manage time series selection as collection list

Time series that you have loaded into the time series selection dialog can be combined in a collection list:

▪To do this, mark a time series of the selection in the time series selection dialog.

▪This includes all existing time series.

▪Now open the context menu with the right mouse button, or the Graph main menu item, and select the Manage time series selection as collection list function.

New Time Series Collection List Dialog

Now select a folder in the tree view in the Folder selection box and mark it.

Now enter a new name for the new folder, or

select a name from the drop-down list box.

▪Click the [Save] button to confirm.

The new folder is created in the tree view and is ready for use.

Time series selection window

The time series selection dialog lists the time series that are selected to be displayed in the graph or table, for example.

If you do not want to display certain time series from this selection, you can remove these time series from the selection:

▪To do this, open the context menu (right mouse button).

▪Either select the Remove all time series from lists function, or

▪select the Remove selected time series from list function.

View options

For each measured value, there is a read-only "original time series" and a "production time series" in which the measured values can be validated. (As long as no measured values are changed, both time series are identical. With a validation, the production time series is changed in relation to the original time series.).

▪Specify the selection of a time series when loading the graph or table:

▪Mark the desired option in the View options box.

Context menu options

Remove selected time series from the list

This option allows you to remove one or more selected time series from the time series list. Select several time series by activating the [Ctrl] key and clicking with the mouse pointer

Remove all time series from the list

With this option you remove all time series from the time series list.

Combine selected time series into a collection list

Read section Combine selected time series into a collection list for further information.

Load predefined layouts

Preconfigured layouts by the user can be opened for graphical representations using the context menu.

▪If you have taken over one or more time series into the time series dialog, now open the context menu with the right mouse button.

▪Select the Load predefined layout entry.

▪You can now activate the desired layout in an additional menu.

▪Using this layout, AquisNet now activates the graph display.

The configuration of a layout can be opened using the main menu (Graph item)

Display graph and table

You have now selected one or more time series for viewing and defined a time range for the display.

▪Now click the [View] button, or

▪select the Default view function from the context menu of the time series selection window,

▪or the same function from the main menu item Graph.

You get the time series browser and the Show graph and Show table reports combined on the screen.

General functions of the browser tree view

Rename existing tree entry

The names of entries created by users (e.g. collection lists or station groups) in the tree view can be changed. This is not possible for entries that are used system-wide, such as parameters, station names, etc.

▪Select the tree entry you want to rename.

▪Open the context menu with the right mouse button.

▪Select the Rename folder/collection list function.

▪The field of the name in the tree view is activated for a user input.

▪Change the entry directly in the Name in the tree view field.

▪Confirm your entries with [Return].

Delete tree entry

Note:

You can only delete folders from the system as long as they do not contain any other folders. In this case, the system issues a notification message.

▪Select the (sub)folder you want to delete in the tree view.

▪Open the context menu with the right mouse button.

▪Select the Delete folder/collection list function.

▪Confirm your entries with [OK].

▪The (sub-) folder is now deleted.

Restore time series states in production time series (recovery)

Recovery means: Restore the previous data status of one or more time series by means of information available in a transaction for these same time series. Data is changed within a certain time range. The transaction used only contains data for this time range.

To ensure data consistency, this action is also saved as a transaction. This writes the changes concerning the specific time range into the base production time series. Information on the previous state is again saved ("Save recovery as another transaction").

Recovery for all time series of a transaction

With the Restore all affected time series states in their production time series function, you restore the state of basic production time series before the change that was saved in the opened transaction.

Recovery for individual time series of a transaction

With the Restore selected time series states in their production time series function, you restore the state of basic production time series before the change that was saved in the opened transaction.

Save recovery as another transaction

To ensure data consistency, a recovery is also saved as a transaction. This writes the changes concerning the specific time range into the base production time series. Information on the previous status is also saved.

▪The transaction is transferred to the data storage.

▪The transaction can now be opened in the time series browser in the tree view. To do this, select one of the transaction-related entry points from the drop-down list box.

Filter

Background

▪The time series filter in the data collection center is an important tool to pre-filter the large amount of time series in the system so that evaluations can be carried out more quickly. Thereby you determine the amount of data from which you want to create evaluations via the filter view.

▪The reduced amount of data applies to all selection options (station, station group, parameter, etc.).

▪To use a time series filter, it must have been created in the system beforehand.

Select existing filter

To use a time series filter,

▪select the desired filter from the drop-down list box.

▪The filter selection is located at the top left of the interface.

▪Then check the box on the left of the selection list. Only then the filter is used by AquisNet.

▪Note: You can only select filters that have already been created in the system.

Opening and editing time series filters

To edit a time series filter,

▪select the Filter option from the drop-down list box below the filter selection.

▪The browser tree now shows the existing time series filter.

▪Double-click to call up the configuration of a filter for editing, which is then displayed in the main window, see figure above.

▪Now transfer the desired objects to the lower selection cells with a mouse click.

▪Only these selected objects will be available later when using the filter.

▪By clicking on already selected objects, you deselect them.

Note:

▪For example, if you select only Bree as station, a user with the current time series filter will only have access to time series for station Bree.

▪If you select a station group, you have access to all time series recorded in the stations of this station group with the current time series filter.

▪If you select a parameter, you have access to all time series containing data for this parameter with the current time series filter.

▪If you select a station group, the stations contained in the selection cell are automatically taken over to the Station entity.

▪If you remove a station group from a filter configuration, the station entries are retained. Thus, there is a coupling in the selection, but not in the deselection of station groups!

▪Confirm your adjustments with [Save].

The edits are transferred and taken into account when the filter is selected via the selection list at the top left.

Origins

Background

"Persistent origins" are calculation rules (formation rules) for time series. "Persistent" stands for time series that remain in the system permanently, in contrast to time series that are created temporarily.

Such a formation rule specifies how defined source time series are to be calculated with each other according to a formula in order to obtain the measured values of the target time series.

You can define up to ten source time series depending on the origin type.

When you create a new time series, this means creating an origin for this new time series so that it can be calculated from a source time series.

Example:

The time series "daily mean values", for example, can be calculated from half-hourly mean values.

In this process, a value of the new time series is formed from the mean values of one day. The average value of the next day results in the next entry.

Call up origins

The dialog for origins is integrated into the time series browser. You can open details on the origin of a time series by clicking on the time series or the origin. You can open further functions for the creation of time series via the context menu.

To open origins for time series,

▪expand the tree view (independent of the browser tree configuration) to the time series level.

▪double-click the desired time series:

▪The Origin entry indicates that this is a time series generated by an origin. The plausibility check function is not available for time series generated by emergence:

▪If the time series can be extended with regard to plausibility check entries, the tree entry contains the type of plausibility check(s) used.

▪If the time series cannot be extended with regard to an origin entry or a plausibility checker, it is an import time series for which no plausibility checker has been created.

▪By clicking on an origin entry in the plausibility parameters section (in the right part of the dialog), the parameters of a type are displayed:

Structure of the Dialogue

In the right part of the dialog, three sections inform about the attributes of the time series selected in the tree. You also define the properties of a new time series to be created in these three sections.

The entries below indicate the properties of the displayed time series:

▪Time series section

▪Time series: The name of the time series, consisting of station abbreviation and time series definition, can be freely selected when creating a new time series if the time series is not imported into the AquisNet system.

▪Time series definition

▪Time series type

▪Time period

▪Integration time

▪Source time series section

▪Display of the time series that serve as source time series for the calculation of the time series.

▪The time period of the source time series is smaller than the time period of the target time series when it is created, and is also divisible by it.

▪When using an origin of the free formula type, the time periods of the source time series and target time series must be identical.

▪Origin specific parameters section

▪The origin-specific parameters are different for different types of time series. The table provides information on these correlations. Below you will find the list of origin-specific parameters and explanations of their respective meaning:

▪minimum coverage [%]: The percentage indicates what percentage of the possible measured values must be present in the source time series in order to obtain a value of the target time series that is valid.

▪maximum gap [values]: This value specifies the maximum number of consecutive time stamps in the source time series that can have invalid values during the integration time of a target value for the target value to be valid.

▪minimum coverage if last value is missing [%]: If the last value of the source time series is not present in the integration time, this additional setting of the minimum coverage serves as an additional check of the validity of the time series.

▪Percentile: A K-percentile value defines the value of a measured value time series below which K percent of all measured values lie.

▪Time-Hour-Start: Time with which the start of a period within a day can be defined at which the calculation starts.

▪Calm condition: The Calm condition (in m/s) represents an adjustable limit value with which you can define up to which wind speed calm is assumed. The usual limit value is 0.5 m/s.

▪For values equal to or less than this wind speed, no assignment of the wind direction is made in the display of the concentration rose

▪Limit value/threshold: The limit value defines a value against which all measured values of a time series with time series type "Exceedance frequency" are to be checked for exceeding or falling below.

▪Time offset [sec]: With a time offset, you specify the shift between the time stamp and the integration time. The integration time shifts backwards (clockwise with a positive sign) or forwards (counterclockwise with a negative sign) by the specified offset seconds.

▪With the time offset parameter you can create or calculate time slices (time raster and integration time equal to 24 hours) and time intervals (time raster and integration time unequal).

▪Parameter correction factor: This factor enables the subsequent correction of measured values based on manual input. This way, laboratory readings can be corrected later if laboratory conditions were not optimal. It is also conceivable that an incorrect calibration of a measuring device can be corrected in this way.

The correction is made by multiplying the measured values by the manually entered value. The correction factor is therefore dimensionless.

Time series type, time series definition, origins & origin specific parameters

The terms time series type, time series definition, origins and origin-specific parameters and their functions are closely linked using the two dialogs Origins/Create new time series and Configure time series definitions.

The functional context is therefore explained on the basis of the following points. These points should further anticipate some important information for creating a new time series:

In the Origins/Create new time series dialog, the selection of the time series type is done using the Data type/Time series definition type (TSD type). The time series type is a main component of the time series definition, and thus of the generation of time series.

A specific time series type is therefore created in the system for each time series.

If you want to create a new time series, but the desired time series definition is not listed in the time series definition drop-down list box, you have the option to create the desired time series definition in the Configure time series definitions dialog.

The selected time series type (arithmetic, percentile value, etc.) is decisive for the time series definition and thus ultimately also for the calculation of a new time series: This also determines which origination-specific parameters can be configured in the Origins dialog when creating a new time series.

Therefore, at this point of the "Create a new time series" workflow, the two dialogs Origins/Create new time series and Configure time series definitions are involved.

In the table below the relation of "Time series type" – "Number of source time series" – "Origin-specific parameters" is listed.

Origin templates for time series types

Create new time series

To create a new origin,

▪Open the context menu in the tree view.

▪Select the Create new time series entry.

The Create new time series dialog opens.

Delete time series

With this program function you can remove a time series you have created from the system again. Import time series can never be deleted.

To delete a time series,

▪first select the time series to be deleted in the tree view.

▪If you have marked the time series with a mouse click, open the context menu with the right mouse button.

▪Select the Delete time series function.

A confirmation dialog opens.

▪Now confirm with [Yes] to continue the process, otherwise cancel with [No].

▪By confirming, the system checks whether it can delete the time series without deleting other dependent time series.

▪If there are dependencies between the time series to be deleted and other time series, another dialog opens.

▪It displays how many dependent time series use the selected time series as a source time series.

▪Confirm the dialog with [Yes] to continue the process, otherwise cancel with [No].

▪If the time series has been removed from the system, you will get a message about this, which you should confirm by pressing the enter key.

This completes the deletion process.
