An Electronic Chart is a digital representation of navigational information used primarily in maritime and aviation contexts. It replaces traditional paper charts, providing real-time data about the environment, such as water depths, hazards, and navigational aids. These charts are often integrated with Global Positioning System (GPS) technology, allowing users to track their position accurately. Electronic charts enhance safety and efficiency by offering features like zooming, layering of information, and automatic updates. They are commonly used in conjunction with systems like Electronic Chart Display and Information System (ECDIS), which helps mariners make informed decisions while navigating through various waterways.
