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 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.

  - 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.
    - 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 Scala.
- Recording and Replaying Data
  Data received by Scala can be replayed with Scala Replay application.

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.

About this task

A 3D view of the trawl doors is already in some page templates, for example Trawl Doors (Front)/Trawl Doors (Back).

Procedure

In the top toolbar, select a page with a 3D view of the trawl doors, for example Trawl Doors (Front).
If you have no page in the top toolbar with a 3D view of the trawl doors:
1. From the top left corner of the screen, click Menu > Customize.
2. Enter the password eureka.
3. In the top toolbar, click the add icon .
4. Select a page template in the Standard Pages or Custom Pages panel that has a trawl door 3D view.
If you have twin trawls you can display the clump and if you have twin outrigger trawls you can set which doors are displayed. Right-click the 3D view, then click Configure. Choose from the drop-down menu.
You can also change the viewing angle: looking from the trawl toward the vessel (front), or from the vessel toward the trawl (back).
To change the door or clump model:
1. From the top left corner, click Menu > Settings.
2. Click the Trawl tab and select the models from the drop-down lists.
To change the view angle of the door, right-click the 3D view and choose:
- Horizontal Camera to see the doors from the front:Or back:
- Vertical Camera to see the doors from above.
- Free Camera to adjust the viewing angle yourself, by clicking and dragging the 3D doors.
To display or hide the ground, right-click the 3D view and select or not Display Ground. You should leave the ground displayed, in order to see if the doors are touching it.
