Marine charts are specialized maps designed for navigation on oceans, seas, and other large bodies of water. They provide essential information about water depths, underwater hazards, and coastal features, helping sailors and boaters safely navigate their routes. These charts often include symbols and color codes to represent different types of information, such as buoys, lighthouses, and shipping lanes. Marine charts can be found in both paper and digital formats, with the latter often offering interactive features like real-time updates and GPS integration. They are crucial tools for mariners, fishermen, and researchers who rely on accurate data to ensure safe and efficient travel on the water.
