Nautical charts are specialized maps designed for maritime navigation. They provide essential information about water depths, coastlines, and navigational hazards, helping sailors safely navigate through oceans, seas, and rivers. These charts include symbols and markings that indicate features like buoys, lighthouses, and shipping lanes. Nautical charts are produced by various organizations, including national hydrographic offices. They come in different formats, such as paper and electronic versions, and are regularly updated to reflect changes in the marine environment. Mariners rely on these charts to plan routes and avoid dangers while at sea.
