Data Management and Issuance of Nautical Warnings
The content discusses the development and implementation of the PING project by Shom in Valparaiso, Chile, focusing on the availability of NAVAREA II navigational warnings and the use of PING for nautical information. It emphasizes the automatic generation of S-53 and S-124 forms, ergonomics in NWs production, and the transition to structured NWs. The system ensures equivalence between S-53 and S-124 forms, streamlining the drafting process. Considerations include the adoption by French coordinators, ergonomic adjustments, and efficient NW production with standardized expressions.

S S- -124 Development 124 Development French PING project Shom Valparaiso, Chile 2 - 6 September 2024
S124 DEVELOPMENTS 1. Shom is aiming to have NAVAREA II, coastal and local navigational warnings S-124 datasets available on January 1, 2026 2. Use of PING, the new web national platform for nautical information 1. Online tools for NWs production and NWs cycle of life management 2. Used by Shom (NAVAREA II) and French regional coordinators (coastal and local NWs) 3. S-53 and S-124 automatic dual issuing 4. Online delivery of NWs Valparaiso, Chile 2 - 6 September 2024
WHERE WE STAND 1. Since April 10th, 2024 PING is officially the primary system for issuing NWs in mainland France and PING s portal is open to the public. (https://portail.ping-info-nautique.fr) 2. Operators create and manage NWs using an HMI designed according to their job and skills and reflecting S-124 data model in an ergonomics manner, including drawing tools for geometries. 3. NWs created are stored in the PING s database based on S-124 data model. 4. S-53 form of NWs are automatically generated from PING s database, and next S-124 datasets will also be generated, Valparaiso, Chile 2 - 6 September 2024
CONSIDERATIONS 1. Dual S-53 and S-124 issuing: Principles 1. When a NW is published in PING, the S-53 and the S-124 forms are automatically generated from the same entered data. 2. There is no possibility to alter manually the S-53 form after the generation (no failure in translation encountered). PING automatically delivers the S-53 NW to the NAVTEX station. 3. PING software guarantees that the S-53 and the S-124 forms convey the same information (the two forms are equivalent) with the unique condition that the operator inserts the Position into the Information field. 4. PING provides a facility to insert the figures of the position from the drawing of the geometry. 5. When editing a NW, the operator can see the draft S-53 result.
TRANSLATION INTO S-53 Valparaiso, Chile 2 - 6 September 2024
CONSIDERATIONS 1. NAVAREA II and French regional coordinators in mainland France used PING since 2023 (dozen of operators) 2. French coordinators had the habit to use a lot of S-53 NWs text models. Ergonomics adjustments were necessary to facilitate the drafting of the structured NWs. Ergonomics of HMI is crucial to swift from a textual NW to a structured NW. Valparaiso, Chile 2 - 6 September 2024
CONSIDERATIONS 1. Thousands of NWs had already been produced using PING and so, using the S-124 data model. There is no case where it was impossible to apply the data model. In some cases, different encoding options are possible. 2. The NW is drafted and published in few minutes (less than the maximum 30 minutes). 3. To reduce the drafting of free text, we added a list of standardized expressions to be inserted into WarningInformation/information Wide berth requested, Navigate with caution, Hazardous to navigation, In progress, Until further notice, etc. => The quality of NWs is improved (less typos, less position mistakes) Valparaiso, Chile 2 - 6 September 2024
CONSIDERATIONS 1. The use of some S-124 concepts by coordinators still needs to be reinforced: 1. Hazards types 2. Period of an hazard 3. NW divided into parts Valparaiso, Chile 2 - 6 September 2024
CONSIDERATIONS 1. Some notions of the S-124 data model are not implemented because, for the time being, we consider that they are not useful for French NWs. This simplifies the drafting of the NW. Not implemented: 1. NAVWARNPreamble/title 2. NAVWARN/affectedChartPublication 3. NAVWARNPart/featureName 4. NAVWARNPart/featureReference 5. NAVWARNPart /restriction 6. TextPlacement 2. No validation checks implemented - We expect to use a third-party software when available Valparaiso, Chile 2 - 6 September 2024
NEXT 2024-25 1. First experimental delivery of S-124 ed.1 datasets from the PING database 1. S-124 Exchange sets including metadata, based on files (1 NavWarning is 1 file), files signed for authentication & integrity 2. With a basic implementation of SECOM: secured delivery in pull mode of all the NWs in-force in a series using SECOM GET REST API 3. Note : PING already offers a REST API but it is not compliant with S-124 ed. 1 and SECOM. This API is used by our Nav&Co mobile app for pleasure boaters. 2. PING s code in open source (EUPL) 3. PING to be deployed in French oversea territories Valparaiso, Chile 2 - 6 September 2024
NEXT 2024-25 1. A training instance is available for everyone to experiment NW production using PING at your pace 2. Contact Yves Le Franc to get an access (your IP address is the only requirement) yves.le.franc@shom.fr Valparaiso, Chile 2 - 6 September 2024
