Which area boundary can clutter the screen when using the night palette?

• A. Plain
• B. Overlay
• C. Polygon
• D. Grid

Answer: (A)

The plain area boundary can clutter the screen when using the night palette. In an ECDIS, a night palette is typically designed to enhance visibility and reduce glare in low-light conditions, which means that it uses colors that are easier on the eyes in the dark. The plain area displays colors meant to be straightforward and unobtrusive, but when overlaid with other data or navigational elements, they can create a cluttered appearance, making it harder for the navigator to discern critical information. Overlay boundaries, on the other hand, are meant to display additional navigational information, such as radar or AIS data, and are often more transparent to prevent clutter. Polygon boundaries, which are used to define specific areas for representation (such as restricted zones or environmentally sensitive areas), can be clear and distinct and are typically designed to stand out rather than blend in. Grid boundaries serve a different purpose in navigation that relates more to referencing positions than to creating visual clutter. In summary, when using the night palette, the plain area boundaries can inadvertently add visual noise, making the navigation data harder to interpret, thus significantly cluttering the screen.
