Radar overlay
You can combine the chart with the radar or MARPA functions to provide target tracking or to help you distinguish between fixed objects and other marine traffic.
You can enhance the use of your chart by combining it with the following radar features:
•Radar range synchronization.
•MARPA.
•Radar overlay (for distinguishing between fixed and moving objects).
Radar range synchronization
When synchronization is switched on:
•The radar range in all radar windows, changes to match the chart scale.
•‘Sync’ is indicated in the top
•If you change the radar range, in any radar window, all synchronized chart views change scale to match.
•If you change the scale of a synchronized chart window, all radar windows change range to match.
Using the radar to view MARPA targets on the chart
The Mini Automatic Radar Plotting Aid (MARPA) function is used for target tracking and risk analysis. When MARPA is set up in radar mode or radar overlay, all MARPA targets are displayed in the chart window and associated MARPA functions can be accessed via the chart.
Using radar overlay to distinguish between fixed and moving objects
You can overlay radar image data over your chart image allowing better distinction between fixed objects and other marine traffic. For best results, switch on
