Depth display settings
Various settings are available to visualize the depths and depth area:
• Shallow contour: Limit for shallow waters. Depth less than Shallow contour will be
displayed in dark blue color.
• Safety contour: Contour related to own vessel. To be used by the system to distinguish
between safe and unsafe water. Depths between Safety contour and Shallow contour
settings are displayed in medium blue color.
• Deep contour: Limit for deep waters. Depths between Deep contour settings and Safety
contour setting are displayed in light blue color.
• Safety depth: The ship's draft plus under keel clearance. Sounding are displayed in black
if they are equal to or more shallow than the safety depth settings. Soundings are
displayed in grey if they are deeper that the set value.
• Color mode: Number of colors used to indicate depth:
-
2 color mode: unsafe water (from the 0 meter contour to the safety depth) and safe
water (from the safety depth and deeper)
- 4 color mode: very shallow area (from the 0 meter contour to the shallow contour),
medium shallow area (from the shallow contour to the safety contour), medium deep
area (from the safety contour to the deep contour), and very deep area (from the deep
contour and deeper)
• Portrayal style: You can select to display the chart symbols in the S52 portrayal style or in
the INT1 portrayal style. The S52 portrayal style displays the chart symbols according to
the ECDIS standard, while the INT1 style displays the chart symbols and color as required
in the Symbols and Abbreviations Used on Admiralty Charts publication.
• Chart symbol size: Option for selecting size of chart symbols
• Symbolized boundaries: Displays boundaries lines as symbols rather than as plain lines
• Paper chart symbols: Displays navigation aids as paper chart symbols rather than as
simplified symbols. This option is available only for the S52 portrayal style.
• Danger symbol: Displays dangerous object with a danger symbol
• Scale min: Reduce the scale-dependent objects (objects with the attribute SCAMIN) scale
at which they are drawn. At display scales smaller than SCAMIN the object is not drawn.
For example, an object with a SCAMIN value of 50,000, indicating a scale of 1/50,000, is not
drawn on a display of 1/60,000.
• Shallow pattern: Fills the shallow area from the coast line to the safety contour with a
parallel pattern.
2 color mode 4 color mode Shallow pattern
• Full light lines: Displays light sector legs in real length rather than as short lines
• Leg activation scale: Set the scale to turn on the light sector feature. Additional options
appear:
-
Set the distance from the vessel to the navigation light (Light distance) and distance
from the vessel to the sector leg (Distance from leg) to determine when the sector
light is shown on the chart.
- Enable light character: Displays a blinking light character
