values for Shallow Contour, Safety Depth, Safety Contour and Deep Contour. Soundings on the electronic chart,
which are equal to or less than the value of Safety Depth, are highlighted. See below pictures for multi-colour
presentation and two-colour presentation. Selection of multi- and two-colour presentations can be done by selecting

In the multi-colour presentation four colours are used for depths. If input Safety contour does not exist in electronic
chart, system selects automatically next available deeper depth contour as Safety contour. For example input value is
8 m, but there is no 8 m depth contour in electronic chart, the system automatically selects next available deeper
depth contour (10 m) as Safety contour. Depth contour value of 10 m is presented as Safety Contour in this
electronic chart.
