I failed finding your proposal in this thread, fraidf or frahdf. Where else did we talk about departement / district border label names? I'm sure that I was told to replace Xxx/Yyy non-region border labels by the road number of the route beyond the border. Minimum when the border / wp is at a junction. Which regions out of France have systems changing at district borders? I think it's important because there are a lot of wp labels named according to this approach... Was it when talking about wp label rules?
I did say this one, but it's not the route over the border:
D924
- HDF/IDF -> D929
but that's as it meets
D929 in that system and region. In fact it also meets D4 from that system, but not in that region.
And here, I ask you to rename
a point which you've named after the intersecting side street rather than the border. Note that I don't have you call it D54a (the departmental road in Nord), but instead the border.
D163Oig - RueFus -> PdC/Nor (no intersecting route, but the route on the continuation of this route on the other side of the border)
I believe the confusion is coming from this one:
D173 - Yvl/HdS_N -> Yvl/HdS, Yvl/HdS_E -> D907 (I know the D907 is in HdS, and the D307 ends at this point, but a border point in middle of the route is wrong)
You will, however, note that I explicitly make a comment that the route I'm asking you to label is in a different department (and system)
due to the mutual assumption that this was not good labelling, but point out that it's better than the terrible alternative we start with.
Which regions out of France have systems changing at district borders?
Obviously there's the Corse/Alsace exceptions where two departments share a system because the departments don't maintain roads but the collectivity does, and a few places where one department maintains a route in another department, but the Route Departmental systems explicitly change at departmental boundaries such as these - after all that's sort of their whole schtick!
And all-but-two of the routes I've reviewed so far have used departmental boundary labels where the route ends at one (providing it doesn't meet another route of the same system at that point). Both of which are in this system - and are exceptional even within this small system - at least 10 times that number of points use the boundary labels
within this system, despite that system being small.
