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

  1. Click Menu > Customize and enter the password eureka.
  2. 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.

  3. Click and drag inside the view to move it.
  4. 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.
