objects.

Navigation Editor
Navigation editor overview
The Navigation editor gives the user the possibility of working with the electronic chart in the
same way as with the paper chart:
•
Preparation of a harbor arrival or a passage through a dangerous area by adding
temporary information on the chart.
•
Planning the route more safely by drawing restricted or dangerous zones.
•
Manually plotting the position of the ship.
Information and objects plotted with the NE (Navigation Editor) are stored and presented in
a special layer called NE layer that is displayed on the top of the electronic chart.
NE layer contains objects (lines, arcs, chart annotations, current information) that are
temporary objects, displayed on the chart until such time as they are deleted.
The ECDIS does not allow the possibility of storing these objects to file and reloading them in
the system on request.
The different objects available are:
•
•
•
•
•
•
•
"Parallel and perpendicular lines"
•
"Chart annotation and caution"
The Multi-plotting mode allows plotting several objects without having to select the plotting
tool for each object (see
Multi plotting mode
To plot an object requires:
1.
Select the appropriate tool, Bearing line, Arc, Point…
2.
Enter eventually additional information.
3.
Click on the chart.
In the current plotting mode, the plotting tool is deactivated when the object is defined.
To plot other objects of the same type requires selecting the same tool for each object.
When the tool is selected with the right button of the mouse it remains active after the
object is plotted and other object of the same type can be plotted on the chart without tool
selection.
This facility is available for the Arc, Point, Polyline and Chart annotation.
To de-select the tool click again on the tool button or select another tool.
