3.3
Existing Chart Symbols
3.3.1 Reproduction of paper chart symbols on ECDIS
Most of the symbols in IHO INT 1 "Symbols used on (paper) charts" have been
translated for use on ECDIS. The ECDIS Chart 1 gives details, and is divided into
lettered sections
in the same way as INT 1. The following notes apply to these symbols
(1) Depth contours are not labelled by the ECDIS. The Safety Contour is highlighted, and the mariner should use cursor picking for other contour values.
(2) Light sectors. It should be possible, on request, for the mariner to be capable of identifying the colour of the sectors affecting the ship, even if the lights involved are off the display.
