What type of display screen shows the direction for navigation?

A digital map is an essential tool for navigation as it provides real-time graphical representations of the geographical area, including various features such as waterways, landmarks, and navigational aids. This type of display screen allows users to view their vessel's current location, set waypoints, and visually track courses while showing the direction to be taken.

Digital maps often incorporate GPS data, which provides accurate positioning and can continuously update the displayed information as the vessel moves. This capability makes navigating more efficient and effective, as it simplifies course plotting and helps in avoiding hazards.

In contrast, other display types like analog gauges are primarily used for monitoring specific parameters, such as speed or fuel levels, but do not provide directional guidance for navigation. Electroluminescent screens can enhance visibility for various displays but are not specifically designed to show navigation paths. A projector interface may present information visually to a group but is not typically used for direct navigation by an individual on a vessel.
