Data Modelling

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 IALA remit, including Aids to Navigation (AtoN), Vessel Traffic Services (VTS), positioning systems and communication systems.

IALA has worked closely with IHO and other bodies to develop S-200 product specifications within its areas of responsibility, in particular AtoNs and VTS. A supervisory structure (IALA Guideline 1087) has been established within IALA to manage its domain, which, with the approval of IHO, has been allocated the numbering series S-201 to S-299.

The IALA eNAV Committee oversees this work through the Harmonization Working Group (WG1). IALA Guideline 1106 sets out the process for preparing S-200 product specifications and has been revised and updated as experience has been gained. 2 product specifications (S-201 and S-240) are ready for review and approval and several others are under development.

S-201 Product Specification

The S-201 Aids to Navigation (AtoN) Information Product  Specification provides a common structure  for the exchange of information about AtoNs. This includes buoys, beacons, racons, lights, sound signals and AIS. The product  contains the positions, properties, operational status and general comments related to an AtoN.

The S-201 PS can be used to exchange AtoN information in a consistent  form between Lighthouse Authorities, Hydrographic Offices and other organizations, including commercial and professional agencies.

The draft version of S-201 is attached below.

Please note that the Product Specification includes zip files, containing potentially executable code (xml). Every effort has been made to ensure that this does not present a cyber security risk. However files are opened and used at your own risk.

It should also be noted that this code is not finalised and no attempt should be made to run it.
