scrttv

Real-time trace view.

Description

scrttv visualizes real-time waveform data (see scrttv overview) of a defined window length (default=30 minutes) and of defined streams/stations (default is primary station channels). scrttv switches between two modi. In the normal mode the trace order is given by the configuration file. In the event mode the traces are sorted by epicentral distance to the latest origin received from the messaging. Additional to the waveform traces information about gaps, picks and the time of incoming origins are displayed.

scrttv overview

An example of scrttv and the dialog window to set preliminary origin. Tab 1-2 = enable/disable tab; Counts = maximum counts of a stream; Info = stream information (station, network and channel code); Filter = filter status of the traces; Status = connection status.

scrttv shows two tabs: the enabled and the disabled tab (see scrttv overview: Tab 1-2). Stations listed in the disabled tab are excluded from processing (e.g. 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.

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.

Artifical origin.

In case the operator recognizes several seismic signals, 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 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.

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 lenght 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

Enable / Disable Stations

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.

Stream Filtering

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

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
   

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.

Offline Mode

To start scrttv without connection to the messaging use the option --offline or simply provide the miniSEED data file, e.g.:

scrttv [your miniSEED file]

In offline mode event parameters given in SCML files, e.g. from offline processing, can be loaded using the File menu.

If enabled, then all traces are sorted by distance when a new origin arrives.

showPicks

Default: true

Type: boolean

If enabled, picks are shown.

filter

Default: "RMHP(2)>>ITAPER(5)>>BW(3,0.5,8.0)"

Type: string

Define the filter to be used when filtering is activated. This is only being used if filters is not set otherwise it is overridden. This option is mainly for backward compatibility.

filters

Type: list:string

Define a list of filters that is cycles through when pressing ‘f’. This options supersedes the filter option. If not defined then filter is used instead. If defined then this filter list is used exclusively and the filter option is ignored.

autoApplyFilter

Default: false

Type: boolean

Activate the first filter of the configured filter list after startup. This is equivalent to pressing ‘f’.

bufferSize

Default: 1800

Type: int

Unit: s

Define the buffer size in seconds of the ring bu of each trace.

allTracesInitiallyVisible

Default: false

Type: boolean

If set to true, all traces will be visible on application startup independent of data availability.

autoResetDelay

Type: int

Unit: s

Time span in seconds to switch back to the last view after an origin caused resorting. The default is 15min.

streams.codes

Type: list:string

The channel list is intersected with all channels configured in inventory unless –no-inventory is used.

Examples:

default : display all streams configured by global bindings

default, PF.BON.00.HH? : display default and all HH streams of PF.BON.00

streams.blacklist

Type: list:string

If not empty then all stream patterns are part of the blacklist. The blacklist is only active if “streams.codes” is omitted and the default stream list according to the bindings is to be shown. Each pattern can include wildcards (either ? or *). The pattern is checked against the channel id which is a concatenation of network code, station code, location code and channel code separated with a dot, e.g. “GE.MORC..BHZ”.

The final trace color will be interpolated from the normalized gradient where the value range is scaled to [0,1].
