S-200 Data Modelling

IALA is responsible for managing the S-200 domain and creating product specifications for the GI registry. This range, which spans from S-201 to S-299, is compliant with the IHO S-100 standard and covers various areas within IALA’s scope, such as Aids to Navigation (AtoN), Vessel Traffic Services (VTS), positioning systems, and communication systems.

IALA has collaborated closely with IHO and other organizations to establish product specifications in its respective areas of responsibility, particularly in AtoNs and VTS. To oversee this domain, IALA has created a supervisory structure, as outlined in IALA Guideline G1087, and has been granted the numbering series S-201 to S-299 through IHO approval.

The IALA ARM Committee is responsible for managing this work, and IALA Guideline G1106 outlines the process for developing S-200 product specifications, which have been updated based on previous experiences. Some of the product specifications are currently available for the test and validation process.
