MSC.530(106) requires user-selectable categories to be created for the navigational hazards alerts #159
Comments
Decisions made at Portrayal subWG meeting on 09/04/24 Leave issue open until MSC.530(106) implementation details are finalised (currently in discussions with the ENCWG). Below is the latest A&I mapping table for references to existing Alert Highlight'' VGs |
Any update? If not, I will retarget the PC implementation to v1.4. |

My Proposal: Note: My understanding is that the ENCWG change proposal is not looking at changes to VGs for managing of A&I. This would be an S101 specific implementation (an enhancement to get us closer to MSC.530 requirements). Functionality: By switching the 'Alerts Highlights' VG layers OFF, mariners won't get an A&I when their 'safety framework' in Route Planning or Monitoring clashes with the corresponding feature/attribute combinations as listed in https://github.com/S-101-Portrayal-subWG/Working-Documents/files/15241188/S-101.Alerts.Mapping.Table.v10.20240507.xlsx. This means no yellow/red highlight, sound or entry in the Alerts Panel. |
Decision at PsWG meeting on 10/7/2024 IHO interpretation of requirements is that there is only one user-selectable category for NavHazards, which is supported by the current implementation. Some changes were done to remove the Alert highlights from VGL and treat them as Independent Mariners' selctors not linked to ECDIS Display Modes, etc @DavidGrant-NIWC -Need confirmation of any PC changes done during the meeting Refer to iho-ohi/S-164-Sub-Group#88 regarding the impact the deselection of Alerts highlights would have on the entries reported in an ECDIS Alerts panel. |
Implemented by PC 414 NOTE: Since Hannu indicated the alert highlights should not be exposed to the user these are now only provided using viewing groups. The viewing groups are not included in any viewing group layer or display mode. I expect that the ECDIS will not directly expose these viewing group selectors to the user but will instead tie their operation to existing GUI components of the ECDIS.

Implemented in PC 1.4.0 |

User-selectable object categories need to be created for the navigational hazards alerts. Each category requires a separate viewing group which will be associated with the corresponding alert highlight. Alerts associated with prohibited areas/areas with special conditions already provide user-selectable categories corresponding to viewing groups 53012-53024.
Note that there are only five unused viewing groups available in the 53010-53029 block currently being used for alert highlights. We may need to also use values from 53001-53009 if more than five user-selectable categories are added.
