In E-NAV, what does "chart accuracy" refer to?

Chart accuracy in electronic navigation refers to the degree to which the electronic chart aligns with real-world features and geography. This is crucial because navigational decisions are based on the information provided by the chart, and any discrepancies can lead to errors, miscalculations, or accidents. A highly accurate chart will represent landmarks, hazards, depths, and other critical maritime information correctly, ensuring that navigators have reliable data to make informed decisions while at sea.

Other aspects like the cost of creating charts, the frequency of updates, and the usability of chart software, while important in their own contexts, do not directly pertain to how accurately the chart correlates with the actual environment. Thus, focusing on accuracy ensures safe and effective navigation, which is the fundamental purpose of electronic charts.
