Including: 3 parts. The International Hydrographic Office and other hydrographic authorities publish Electronic Navigation Charts (ENC) for navigators and mariners. ENCes conforms IHO standard S-57, which sets out the specifications for such publications. ENCs are perhaps the most anticipated and most critical component of navigation tools. Built to international standards, ENCs are essentially a database of vector chart features that can be intelligently processed and displayed by electronic charting systems. As smart charts give the user much more information than what paper charts offfer. They can be incorporated with Global Positioning System satellite data and other sensor information (water levels, winds and weather) to significantly improve navigation safety and efficiency by warning the mariner of hazards to navigation and situations where the vesseles current track will take it into danger.
