AIS Application-Specific Messages (ASMs) transmitted in binary format will be increasingly used to digitally communicate maritime safety/security information between participating vessels and shore stations. This includes time-sensitive metrological and hydrographic (met/hydro) information that is critical for safe vessel transits and efficient ports/waterways management. IMO recently published a new Safety-of-Navigation Circular (SN.1./Circ.289) that includes a number of meteorological and hydrographic message applications and data parameters. While there are no specific display standards for AIS ASMs on shipborne or shore-based systems, IMO Has also issued general guidance for the presentation/display of ASMs (SN.1/Circ.290). It includes specific mention of conforming to the e-Navigation concept-of-operation. For any new IHO S-57 or S-100-related product specifications dealing with dynamic met/hydro information, IHO and its Member States should use the same data content fields and parameters that are defined in IMO SN.1/Circ.289. Also, there is a need to consider the implications of IMO guidance regarding the presentation/display of AIS ASMs on ECDIS.
