Navigation Plotter
The Navigation Plotter
The Navigation Plotter Window uses GPS data to display the current
location of the surface vessel. The boat is represented by an icon that is
pointed in the direction of the course or heading (if the heading is
available and if the boat icon option has been selected in the Plotter
Settings window).
3.2.4.1.1 Using the Plotter
The swath coverage
during an operation
The SONAR swath is displayed to show the estimated coverage. The
coverage for the left (port) channel is shown in red, and the swash coverage
for the right (starboard) channel is shown in green. The boat's path is
displayed with a black line. The Plotter will not draw a swath when the
SONAR is off or if that option has been deselected. Some data is necessary
for the Plotter to show a track; that data may be simply a rub check or by
having the SONAR on for a second.
No Layback
Layback set
If
a Layback Event has been created, the Plotter will
also show a towfish and the swath data will no
longer show from the back of the boat, but rather
from the back of the towfish icon. The position of
the towfish icon relative to the boat will depend on
the current entered data.
