[Tagging] Where should name tags be added on administrative boundaries?

[Julien Etienne]

I’m thinking about expanding the administrative boundaries in my area, and
from what I’ve found in my research, the most effective approach involves
creating a relation and specifying roles like ‘outer,’ ‘admin_center,’ and
‘label’ as detailed on the wiki page:


https://wiki.openstreetmap.org/wiki/Relation:boundary 2



However, I’m a bit unsure about where to add name tags. Should I
exclusively add them on the label node, only on the relation, or on both
the label and relation?


Looking at examples from around the world, it seems that name tags are
often found on both entities but aren’t consistently synchronized, which
could lead to inconsistencies.

I was under the impression that the definition of the coastline was 
the average between high and low, not the high tide mark, based on 
what I had read on some wiki page.  I think that there must be 
conflicting guidelines on the wiki since I've noticed two conflicting 
mapping styles.


What style do people think is better?  Is there an advantage to one 
over the other?


For a mapper gathering data it is much easier to estimate the high tide 
mark - either from being there at hi tide or estimating it from wave 
patterns and float-sum left behind. For low tide you'd have to get your 
timing right.
If you want the middle then you need both hi and low - at least twice 
the work. So for making the map data gathers job easiest - high tide 
only please.


Also, is there a good way to map the coastline as an area representing 
the low tide to high tide difference? Adding some tag like tidal=yes 
to areas representing that shape is the best I've found, but tidal=yes 
can also be used to mark that some water or marsh is tidal.


Sorry but I don't map low tide ... too many other things to map! Good 
luck if you want to do that.
