This means that UpdateInformation should be able to 'retain and expose' the symbology of the deleted feature when Mariners perform the 'ENC Update review' process in ECDIS. The feature must not be part of the dataset in the sense that it can't be visible during route monitoring or planning or trigger alarms, etc. In practical terms a deleted feature does not longer exist but, somehow its symbology should be retained so it can be used when reviewing ENC updates.

with it through a new information type.UpdateDeletion
) which can carry the characteristics of the deleted feature/spatialDecisions made at Portrayal subWG meeting on 18/10/23
The group decided to proceed with Option C above:
Portrayal wise, only the Update (delete) pattern will be shown
the symboogy of the feature which has been deleted will not be shown.
Encoding wise:
Also, if UpdateINformation end up replacing the current 'ENC Update Review' functionality in ECDIS, S-98 Annex C (C-12.11.2.2) will have to be updated to remove the requirement to 'overwrite' or 'superimpose' CHRVDEL01 or CHRVDEL02 on the original symbology as this one won't be retained in S-101.
Proposal - Symbology Update: If the 'original ' feature won't be depicted anymore it may be worth considering the following changes to the 'Delete' symbology:
Point: Enclose the CHRVDEL01 symbol using a thin line (same than the 'moved' arrow).
Curve and Surface: Add a thin line (same than the 'moved' arrow) underneath the CHRVDEL0n symbols
[ ] Alvaro - Create Test datasets (once production tools are updated to handle FC 1.2.0) and supply to NIWC for testing of portrayal rules.
Decisions made at Portrayal subWG meeting on 10/04/24
Do not approve the use of an orange circle to support the current symbology for UpdateInformation Point features having updateType=2 (delete).
Approve the use of an orange thin (0.32mm) solid line for UpdateInformation Curve & Surface features having updateType=2 (delete) (as per screenshots in previous comment).
The line symbology above is to be added to the existing 'Delete' symbology (CHRVDEL1). It does not replace it.
[x] NIWC to update UpdateInformation rule for Curves and Surfaces having updateType=4 to support Testing - Target is PC 1.3.0**. Upload screenshots when available.
Portrayal of delete (ignore the adds with no associated feature - there's some issues with this old data):
Implemented in PC 1.3.0
