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 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.

  - 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 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.

Before you begin

You must be in Customize mode to do this task.

You must have:

Incoming GPS data and heading data.
Spread or Slant Range sensors with bearing measurement
Warp lengths or Slant Range sensors giving distance to vessel

Procedure

From the lower part of the control panels, click Customize.
The Customize panel appears.
Click + drag Chart to the page.
Drop it in a yellow area.
The chart view is displayed. The blue trail is the heading of the vessel, red trail is the port door and green trail is the starboard door.
If the view looks empty it might be because the view is not centered on the vessel. Right-click the view and click Center on Ownship or Center on Ownship and Trawl.

What to do next

Deactivate the Customize mode when you have finished customizing pages: click Menu

> Customize again.
