You can display the location and trajectory of the trawl behind the vessel if you receive GPS data and have door positioning sensors.

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.
  - 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 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

Open the customization panel, then go to Geographic.
Click + drag Chart to the page.
Drop it in a yellow area.
The chart view is displayed.

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


View
	White Background: change the chart background to white instead of black. Center on Ownship: center the view on the vessel only. Center on Ownship and Trawl: center the view on both vessel and trawl. Tip: If the view looks empty it might be because the view is not centered on the vessel. Select one of these last two options.


Ownship
	Draw Ownship track: displays the path of the vessel, based on the GPS position. Draw GPS positions: displays points corresponding to the raw GPS positions.


Trawl
	Display Door Tracks: displays the path of the doors, according to the door positionning data. Green track is starboard door, red track is port. Display Net Tracks: displays the path of the headline. Tip: For a more accurate position of the headline, complete the trawl measurements in Settings > Trawl > Net. Display Positionning Filter Data: used for development only. Display Positionning Sensors Data: displays raw data used to get the trawl position.
