A4.3 CM93/3 Chart Display
A4.3.1 Introduction
CM93/3 charts are vector charts displayed together with ENC (S57) and CM93/2 charts. These charts have the
priority order shown below.
CM- ENC
CM93/3 Prof and CM93/3 Prof
CM93/2
If there is available the same navigational purpose charts over the area, priority is as shown above. Areas where
ENC is not available CM-ENC are shown, CM93/3 Prof or CM93 Prof+ and CM93/2 are available, CM 93/3 is
displayed. Areas where ENC and CM93/3 Prof or CM93/3 Prof+ are not available CM93/2 is displayed.
The chart legend, which provides various data about the chart currently displayed, can be toggled on and off by
placing the cursor in the sidebar, clicking the right mouse button, choosing Chart Legend from the menu then
pushing the scrollwheel.
This system is capable of showing more than one S57 chart at a time. This feature is called the multi-chart display.
If one S57 chart does not cover the whole display, the system will open more S57 chart cells for display, if
appropriate cells for the displayed area are available. The chart legend shows information about S57 charts
displayed on the electronic chart display area. The information is displayed with reference to your ship's position if
automatic TM reset is active, or with reference to the current position of the cursor if automatic TM Reset is OFF.
