Which of the following describes a chart plotter's functionality?

A chart plotter is primarily designed to enhance navigation by integrating GPS data, allowing mariners to determine their position and plot their course on electronic nautical charts. This capability enables real-time visualization of the vessel's location, aids in route planning, and enhances situational awareness by displaying other important data such as depth soundings, hazards, and waypoints.

The integration of GPS data is crucial because it provides precise and reliable positioning, which is vital for safe navigation in various maritime conditions. This functionality helps navigators make informed decisions, ensuring that they stay on course and avoid potential obstacles or dangers.

In contrast, while organizing crew schedules and safety drills, providing real-time weather updates, and measuring fuel consumption offer valuable functions in maritime operations, these features are not central to the chart plotter's primary purpose. The essence of a chart plotter lies in its ability to combine navigational data through GPS, thereby facilitating safe and efficient maritime navigation.
