OpenCPN S52 Display Principle Error

[epilot10]

In OpenCPN Version 2.1.0 Build 624a,

I see something that I consider a major S52 mistake :

In the ToolBox menu,

Vector charts /Mariner's Standards :

the Mariner's standards are not the objects written there. These objects are those belonging to the 3 different categories: Base, Standard and Others.
According to S52, you are not allowed to remove any object belonging to Base category.

The Mariner's objects are objects that the mariner can add on the chart like a waypoint, a route, a legline, a VRM, the OwnShip shape.

At the present type, a user can remove anything, like a buoy, a bridge. He shouldn't be able to do so. These objects are in the Base category.

You make a good point.

The intent of this user selection is to allow arbitrary display of object feature classes, whether or not S52 compliant. This capability is not normally available in Type Approved ECDIS systems. Some users find this valuable, especially for cm93 which has some non-standard classes.


Perhaps we should change the terminology of "Mariners Standard" on OpenCPN to something like "Mariners Choice". We could also display some onscreen warning to the effect that some features may be suppressed when this mode is enabled.

Thanks for the feedback

What about providing both? Make "Mariners Standard" comply, but have another set "Full Control" or something that is fully customizable? That may reduce the confusion... Just an idea...

I would keep the term "Mariner" for S52 Mariner's objects.

I would rather use the term User choice. Charted objects can only belong to one of the 3 groups: Base, Standard and Other.

If the user selects one of the 3 groups, he will get all the objects belonging to his specific choice. If he wants to change his display by adding objects to Standard, or removing some objects from Others, he can do so but he can only do it if he chooses the "user" .

So there are 3 groups of objects, but there are 4 choices of display for the navigator : Base, Standard, Other and User.

One thing to keep in mind, we cannot remove any object that belong to the Base group.

On some ECDIS, this classification is not clear. On others, it is too permissive.

I hope that these few words clarify the subject.
