Customizing the Display of Data
3D Views
You can display 3D views of different elements from the system, for example the trawl doors or trawl speed sensors.
Displaying the Trident View
Trident sensors have a dedicated 3D view, showing the echogram beams, the sounding range, the depth and roll values of the sensor.

Display Configuration
Read this section to know how data are displayed on Scala2 and how to change their display.
- Control Panels
- Customization Panels
  The customization panels contain customization options for the data.
- Receiver Data
- Using the Virtual Charger Room
  You can display the fleet of sensors in Scala2 Virtual Charger Room, when sensors are connected to the Dock or trawling.
- Creating Data Pages
- Managing Windows
- Customizing the Display of Data
  - Echograms
    Echograms are a representation of what is detected by the sensors with the acoustic signals.
  - Zooming on Timestamp and Distance Scale
    In echograms and history plots, you can zoom in and out on the distance scale and timestamp and move them along.
  - Sensor Numerical Data
    Data such pitch and roll, temperature, depth can be displayed in dials, gauges, history plots or text format.
  - 3D Views
    You can display 3D views of different elements from the system, for example the trawl doors or trawl speed sensors.
    - Using the MultiTrawl View
      You can display data from A2S door spread sensors on a 3D view of the trawls and doors.
    - Using the MultiDepth View
      You can display a 3D view showing the trawl gear and the echogram images received from a Door Sounder and Door Explorer.
    - Changing the Number of Trawls
      You need to remove specific clumps when reducing the number of trawls in water.
    - Displaying the Trident View
      Trident sensors have a dedicated 3D view, showing the echogram beams, the sounding range, the depth and roll values of the sensor.
    - Displaying Trawl Door 3D View
      You can display a 3D view of the trawl doors and clump. This way, you can see the movements of the doors and clump.
    - Displaying Trawl Speed 3D View
      You can display a 3D view of the trawl speed sensor to see the positioning of the trawl and the across and along water speeds. You can use this view instead of the dial display, as this is more intuitive.
    - Displaying Vessel System 3D View
      You can display a 3D overview of the vessel system if you have the Scala Full version. To know if you have the 3D enabled, check in Menu > About Scala.
  - Displaying the Chart View
    You can display the location and trajectory of the trawl behind the vessel if you receive GPS data and have door positioning sensors.
  - Displaying a Position Marker
    You can place a marker on plots and echograms to display the GPS position at a given time on the timestamp.
- Setting an Alarm on Incoming Data
  You can be alerted by an alarm when data received have a given value.
- Changing the Default Units
  You can change the default units of data displayed in Scala2.
- Recording and Replaying Data
  Data received by Scala2 can be replayed with ScalaReplay2 application.

Displaying the Trident View

Trident sensors have a dedicated 3D view, showing the echogram beams, the sounding range, the depth and roll values of the sensor.

Procedure

Click Menu > Customize and enter the password eureka.
Open the Customize panel on the left side of the screen, then drag Trident View to a page.

The view is displayed. Port and starboard sides are indicated. The roll values appear in red in the center of the view, on both sides of the sensor.
Click and drag inside the view to move it.

Click the arrow on the right side of the view to show the display options.


Settings
	Display: Choose the viewing angle of the trawl between front and rear. Choose to display the filtered or raw data. True mode: the water surface is fixed so you can see the descent of the sensor. Draw bottom: show the detected seabed. Show sky: display a sky above the sea level. Show depth: display the distance between the sensor and the sea level. Beam width: increase the width of the echogram. Beam persistence (beams): the detections remain longer on the echogram image. Trawl opening Select Apply roll to trawl opening so that the trawl opening (yellow circle) follow the roll movements measured by the sensor. You can enter a value for the trawl vertical or horizontal opening in order to correspond to the reality. Trawl shape: change the shape of the trawl opening, from oval-shaped to a rounded rectangle.


Palettes
	Use these palettes to change the echogram colors. See Changing the Echogram Colors for more details about the palette settings.
