The International Organization for Marine Aids to Navigation (IALA) and the International Hydrographic Organization (IHO) in association with the Turkish Directorate General of Coastal Safety, are hosting the third joint workshop on S-100/200 development and portrayal to be held in Istanbul, Türkiye from 01 to 04 September 2026.

Background
In January 2010 the International Hydrographic Organization (IHO) published S-100 – Universal Hydrographic Data Model, a framework geospatial standard for hydrographic-related digital data. S-100 is aligned with the ISO 19100 series of geographic standards, thereby making the use of hydrographic and other geographic data more interoperable than using the present IHO S-57 data transfer standard.
IALA is establishing the S-200 domain, in consultation with IHO. This domain uses the range S-201 to S-299 for Product Specifications compliant with the IHO S-100 standard, covering fields within the Organization’s remit, including Marine Aids to Navigation (AtoN), Vessel Traffic Services (VTS), positioning systems and communication systems.
The Norwegian Coastal Administration hosted the first joint session in September of 2022 followed by the second hosted by USCG in September 2024.
Process
The workshop will consist of presentations from a range of expert speakers covering topics including an update on S-100 and S-200, various Hydrographic Offices and Marine Aids to Navigation competent authorities sharing their experiences, views and opinions.
Following these presentations, working group sessions will be held with a focus on identifying challenges and experiences covering operations, equipment and training in the S-100 series data, S-200 seriesplus S-98 interoperability and AtoN portrayal from the operational, technical and training perspective.
Objectives
The objective of the workshop is to continue to harmonize and open feedback channels between IHO and IALA regarding Product Specification requirements, development processes, implementation gaps and a way forward.
Topics
The workshop deals with S-100 / S-200 aspects. This will include a range of topics, such as:
- Alignment of international standards
- Operational Data Domain
- Data Quality and Validation
- Secure exchange
- Shared Experiences (lessons learned)
Attendees
Managers, competent authorities, engineering and technical staff responsible for the delivery, operation and management of AtoN would benefit from attending the workshop.
