ATON PRODUCT SPECIFICATIONS – S-201 DATA PRODUCTION TRAINING

LA COFA, Santo Domingo, DOMINICAN REPUBLIC, 25 to 29 May 2026

About the course

This course provides a structured introduction to the principles and processes required for the production of S-201 Aids to Navigation data within the S-100 Universal Hydrographic Data Model. It offers participants a comprehensive understanding of the S-201 Product Specification, relevant markup and modelling languages, and the transition from legacy AtoN data formats to S-100-compliant structures. Through guided instruction and practical exercises, participants will develop the competencies needed to create, manage, and validate S-201 datasets in accordance with international standards

This training is primarily aimed at coastal States in the Meso American and Caribbean Sea Hydrographic Commission (MACHC) region to support the implementation of the S-100 framework, with a particular focus on the S-201 Product Specification for Aids to Navigation data. The course is also open to coastal States outside the MACHC region, as well as maritime professionals interested in developing knowledge and capabilities in S-100 and S-201 data production

Learning Objectives

By the end of this training, participants will be able to:

• Understand the S-100 framework, UHDM, and the role of the GI Registry in developing S-200 data models.
• Interpret GML structures and create basic datasets using relevant markup and modelling languages.
• Read & Apply the S-201 Product Specification to interpret features, attributes, and encoding rules.
• Produce & validate S-201 datasets, including the use of S-101 inputs and standard validation tools.
• Explain the principles of Service Specifications and their relation to service products and service instances in the S-100 ecosystem.
• Perform practical data-production workflows through use cases, guided exercises and scenarios.

Target audience

This training is designed for Aids to Navigation (AtoN) Managers and technical staff responsible for managing, updating, and migrating AtoN data. It is particularly relevant for professionals working in Lighthouse or Marine Aids to Navigation Authorities, Coast Guards, Port Authorities, and other organizations that maintain AtoN registries and databases.

Participants are expected to be familiar with existing AtoN data formats or tools (e.g., spreadsheets, legacy databases, older IALA exchange formats) and now need to transition to the S-201 standard within the broader S-100 framework. Knowledge and basic understanding of Markup and model languages (GML, XML,…) is recommended. The course will support them in understanding, preparing, and implementing this migration.

Lecturers

The Seminar will be facilitated by global experts in S-100, S-200 and data product specification development.

Course Duration and Venue

The course will be held at LA COFA, Dominican Republic Naval Club For Officers, between Monday 25^th to 29^th May 2026.
