Introduction
Nautical charts are fundamental to safe and efficient maritime navigation, providing critical information on water depths, seabed features, hazards, and navigational aids. As maritime operations become increasingly data-driven and technology-oriented, the need for accurate and standardized chart production has become more essential than ever.
This program, developed by Global Horizon Training Center, provides a comprehensive and practical approach to nautical chart production. It integrates hydrographic data processing, cartographic principles, and international standards such as IHO S-57 and S-101, enabling participants to produce high-quality nautical charts for both traditional and electronic navigation systems.
Participants will develop the competencies required to transform raw hydrographic data into reliable chart products, ensuring accuracy, compliance, and support for maritime safety and operational efficiency.
Course Objectives
By the end of this program, participants will be able to:
- Understand the principles and importance of nautical chart production
- Apply international hydrographic and cartographic standards
- Process and integrate hydrographic data into chart formats
- Design and produce paper and electronic nautical charts (ENC)
- Ensure quality assurance and accuracy in charting processes
- Utilize GIS and specialized chart production tools
- Represent navigational features and hazards effectively
- Support maritime safety through accurate chart outputs
