A digitally formatted chart detailing the interconnected inland waterways along coastlines, typically the Atlantic and Gulf coasts of the United States, is used for navigation. This type of digital chart, often in Portable Document Format, allows for easy access and display on electronic devices, providing boaters with essential information regarding channel depths, markers, hazards, and points of interest.
These digital charts are vital tools for safe and efficient navigation along protected waterways. They offer advantages over traditional paper charts, including portability, zoom capabilities, and the potential for integration with GPS systems. Historically, these waterways facilitated commerce and transportation, and the charts continue to support recreational boating and commercial shipping.
