scrttv

Real-time trace view.

Description

scrttv visualizes waveform data in miniSEED format (see Figure below) in real-time or from archives with a defined window length (default: 30 minutes) of defined streams/stations (default: streams defined by global bindings). Additionally, phase picks are visualized.

scrttv can be used for view waveforms, visual waveform quality control or interactive signal detection.

When in message mode scrttv dynamically resorts waveforms: Normally, the trace order is given by configuration, e.g., ordering by epicentral distance from a location given by streams.sort.latitude and streams.sort.longitude. In the event that a new SeisComP event arrives from the messaging, the traces are sorted automatically by epicentral distance to the latest origin received. In addition to waveforms, information about gaps or overlaps, picks and the time of incoming origins are displayed.

scrttv overview

An example of scrttv and the dialog window to associate picks to new origins. Tabs: Enable/Disable; Amplitude: mean and maximum; Stream: station, network, sensor location and channel code; Filter: filter applied traces; Status = connection status to messaging.

scrttv shows two tabs: the Enabled and the disabled tab (see scrttv overview). Stations listed in the disabled tab are excluded from automatic processing (e.g. phase picking). To move a station from one tab to another just drag and drop the trace to the new tab. An alternative solution is to double click on the trace label to disable a trace. Read the section Waveform Quality Control for the details.

Normally, the raw data are displayed. Pressing f the predefined bandpass filter of third order from 0.5 Hz to 8 Hz, BW(3,0.5,8) is applied to the traces. Also zoom functions for the time and amplitude axis are provided. Read the sections <scrttv-filtering> and Waveform Visualization for more details.

Among the configurable parameters are:

• Global bindings:

  • default definition of traces to show (detecStream and detecLocid).

• Module configuration:

  • network, stations, locations and streams to show extending or overriding the default definition (streams.codes),

  • data filters,

  • buffer size controlling the length of loaded data (bufferSize),

  • sorting of traces upon arrival of new origins (resortAutomatically),

  • reference coordinate for sorting traces by default (streams.sort.*),

  • region filters (streams.region.*),

  • grouping of streams with different properties,

  • number of traces to show with fixed height (streams.rows).

• Scheme parameters in global module configuration:

  • trace properties and trace background colors,

  • font and general GUI parameters.

More parameters are available on the command-line:

scrttv -h

Modes of Operation

scrttv can be started in message mode or in offline mode.

• Message mode: scrttv is started normally and connects to the messaging, picks, origins and inventory are read from the database and received in real time from the messaging. Data are received from recordstream.

• Offline mode: scrttv is started without connection to the messaging, picks and origins are not received in real time from the messaging. However, they can be loaded from XML files using the File menu. Data are received from recordstream or from file. The offline mode is invoked when using the option --offline or when passing a file name to scrttv at startup. Example:

  scrttv file.mseed
  

Waveform Visualization

Stream selection

Without further configuration scrttv displays waveforms for streams defined in global bindings. The selection can be refined by configuring streams.codes. Streams with data latency < maxDelay are hidden but shown again when applicable. By default this parameter is inactive. For listing streams hidden from one tab press h.

Time windows

The reading waveforms from RecordStream, the data is displayed for a time window which by default ends at current time or as given by the command-line option --end-time. Initially, the time window takes the length defined in bufferSize or by the option --buffer-size. When reading data directly from file in offline mode, the time window is set from the time limits of the waveforms.

• The length of visible time windows can be adjusted by zooming.

• The end time of the data progresses in continuously in real time (UTC) with the time of the computer clock unless fixed (F8). The end time is fixed during startup when applying --end-time.

• For progressing or rewinding by 30 minutes press Alt right or Alt left, respectively. Data will be loaded immediately.

• You may also freely zoom into any time window. Data and picks will be loaded when pressing Ctrl + r

• Return to default real-time processing by pressing Ctrl + Shift + r or N.

Hint

Gaps and overlaps in waveforms are indicated by yellow and purple areas, respectively. The colors are configurable.

Zooming

Waveforms can be zoomed in and out interactively in amplitude and time. Use the View menu or refer to the section Hotkeys for options. In addition to the actions available from the View menu, zooming is supported by mouse actions:

• Zooming in in time: Right-click on time axis, drag to the right. A green bar appears which is the new time window. Dragging up or down (gray bar) disables zooming.

• Zooming out in time: Right-click on time axis, drag to the left. A red bar appears. The longer the bar, the more you zoom out. Dragging up or down (gray bar) disables zooming.

• Zooming in time and amplitude: Mouse over a trace of interest, use Ctrl + mouse wheel for zooming in or out.

• Zooming around a selected area: Press z and drag an area with while pressing the left mouse button. Press z again for leaving the zoom mode.

Stream grouping

scrttv allows grouping of stations and even streams with different properties, e.g. colors or color gradients.

Stations with 2 groups and different line color gradients. Ungrouped stations are visible with default line properties. The applied filter is shown in the lower left corner. The tooltip on top of station CX.PB19 is derived from streams.group.$name.title.

Configuration

Adjust the scrttv module configuration (scrttv.cfg).

1. Define the groups:

   • add a new group profile to streams.group.

   • set the properties for this group profile. Colors and color gradients are defined by hexadecimal values or by color keyword name. When choosing gradients the colors of the traces within one group will be varied in alphabetic order of the streams.

   • set a group title in streams.group.$name.title.

2. Register the groups in streams.groups.

Viewing groups

1. Open scrttv to view the data.

2. Select Sort by group in the Interaction menu or use the hotkey 5 to sort the traces by their groups.

3. Mouse over a station belonging to a group. The tooltips shows the group title.

4. For maintaining the sorting by groups adjust the scrttv module configuration (scrttv.cfg):

   resortAutomatically = false
   

Phase picks and arrivals

Previous versions of scrttv (< 5.4) only displayed picks with the colors indicating the pick evaluation mode along with the phase hint of the pick:

• red: automatic,

• green: manual.

This hasn’t really changed in later versions but additionally scrttv determines an additional state of a pick called arrival. In scrttv a pick is considered an arrival if it is associated to an valid origin. An origin is called valid if its evaluation status is not REJECTED. When scrttv loads all picks from the database for the currently visible time span it also checks if each pick is associated with a valid origin and declares the arrival state if the check yields true. The visibility of picks and arrivals can be toggled by pressing Ctrl + p and Ctrl + a, respectively. c removes all markers. The configuration parameter showPicks controls the default visibility.

Picks and arrivals can be differentiated visually by their colours. When configured in global module configuration, the same colours are being used consistently as in any other GUI displaying both types, namely

• scheme.colors.picks.automatic

• scheme.colors.picks.manual

• scheme.colors.picks.undefined

• scheme.colors.arrivals.automatic

• scheme.colors.arrivals.manual

• scheme.colors.arrivals.undefined

That visual difference should support the operator in finding clusters of picks and creating new location missed by the automatic system.

The next sections will only use the pick which can be used interchangeable for pick or arrival.

Record borders

The borders of records are toggled by using the hotkey b.

Record borders in box mode on top of waveforms.

Border properties can be adjusted and signed records can be visualized by colors configured in the scheme parameters in global.cfg or scrttv.cfg:

• scheme.records.borders.drawMode: Define where to draw borders, e.g. on top, bottom or as boxes.

• scheme.colors.records.borders.*: Define pen and brush properties.

Waveform Quality Control

Use scrttv for regular visual waveform inspection and for enabling or disabling of stations. Disabled stations will not be used for automatic phase detections and can be excluded from manual processing in scolv. They will also be highlighted in scmv and scqc.

To enable or disable a station for automatic data processing in SeisComP select a station code with the mouse and drag the stations to the disable / enable tab or simply double-click on the station code in the respective tab.

Stream Processing

Filtering

scrttv allows filtering of waveforms. The Filter selection dropdown menu (see Figure above) and the hotkey f can be used to toggle the list of filters pre-defined in filter or in filters. The applied filter is named in the lower left corner. To show filtered and raw data together use the hotkey r.

Note

The list of filters defined in filters overwrites filter. Activate autoApplyFilter to filter all traces at start-up of scrttv with the first filter defined in filters.

Gain correction

The stream gain is applied to waveforms and amplitude values are given in the physical units of the stream by default. For showing amplitudes in counts, deactivate the option Apply gain in the Interaction menu.

Interactive Signal Detection

Beside visual inspection of waveforms for quality control, scrttv can also be used for interactive signal detection in real time or for selected time windows in the past.

Artificial origins

Artifical origin.

In case the operator recognizes several seismic signals which shall be processed further, e.g. in scolv, an artificial/preliminary origin can be set by either pressing the middle mouse button on a trace or by opening the context menu (right mouse button) on a trace and selecting “Create artificial origin”. The following pop-up window shows the coordinates of the selected station and the time the click was made on the trace. Both are used to generate the new artificial origin without any arrivals. Pressing “Create” sends this origin to the LOCATION group. This artificial origin is received e.g., by scolv and enables an immediate manual analysis of the closest traces.

In order to send receive articifial origins and receive them in other GUIs commands.target of the global module configuration must be set and must be in line with connection.username of the receiving GUI module.

Alternatively, picks can be selected and origins can be located as preliminary solutions which are sent to the system as regular origin objects, see section Origin association.

Origin association

scrttv comes with a minimal version of a phase associator and manual locator (Fig. scrttv overview). Picks can be selected, relocated and committed to the messaging system as manual preliminary location. In contrast to the artificial origin operation which requires an immediate intervention with, e.g. scolv, this operation allows to store all those detected origins and work on them later because they will be stored in the database.

Note

More detailed waveform and event analysis can be made in scolv.

Pick selection

In order to select picks, the pick selection mode must be entered. Then dragging a box (rubber band) around the picks in question will add them to the “cart”. The “cart” refers to the list of picks of the manual associated widget used to attempt to locate an origin. Simply dragging a box will remove all previously selected picks. Further options are:

• Shift + drag: Add selected picks while keeping the previous selection.

• Ctrl + drag: Remove selected picks while keeping the previous selection.

If at least one pick has been added to the cart, the manual associator will open as a dock widget.

Note

A dock widget is a special kind of window which can be docked to any border of the application or even displayed floated as kind of overlay window. The position of the dock widget will be persistent across application restarts.

At any change of the pick cart, the associator attempts a relocation and will display the result in the details or an error message at the top.

To add more picks to the cart, shift has to be pressed while dragging the selection box. To remove picks from the cart, Ctrl has to be pressed while dragging the selection box. Picks can also be removed individually from the cart by clicking the close icon of each pick item.

Picks being part of the cart are also highlighted in the traces.

Locating from picks

The associator adds all available locators in the system and presents them in a dropdown list at the bottom. The locator which should be selected as default can be controlled with associator.defaultLocator. The profile which is selected as default can be controlled with associator.defaultLocatorProfile.

Whenever the operator changes any of the values, a new location attempt is being made which can succeed or fail. A successful attempt will update the details, a failed attempt will reset the details and print an error message at the top of the window.

Each locator can be configured locally by clicking the wrench icon. This configuration is not persistent across application restarts. It can be used to tune and test various settings. Global locator configurations in the configuration files are of course being considered by scrttv.

In addition to the locator and its profile a fixed depth can be set. By default the depth is free and it is up to the locator implementation to assign a depth to the origin. The depth dropdown list allows to set a predefined depth. The list of depth values can be controlled with associator.fixedDepths.

Committing a solution

Once a solution is accepted by the operator it can be committed to the system as regular origin as emitted by, e.g. scautoloc. Those origins will be sent to the message group defined by messaging.location and grabbed by connected modules, e.g., scevent and possibly associated to an event.

Alternatively, the button “Show Details” can be used to just send the origin to the GUI group and let scolv or other GUIs pick it up and show it. This will not store the origin in the database and works the same way as creating an artificial origin.
