[Tagging] Rio de la Plata edit war

[Frederik Ramm]

Hi,

it appears that once again mappers are in diasgreement about how to map
the Rio de la Plata, here

https://www.openstreetmap.org/#map=8/-35.154/-56.310

This is a disagreement that had already flared up three years ago, and
is now coming back.

According to Wikipedia, the International Hydrographic Organization
defines the eastern boundary of the Río de la Plata as "a line joining
Punta del Este, Uruguay and Cabo San Antonio, Argentina", which is what
has been the case in OSM until now:

https://www.openstreetmap.org/way/186710973 (the coastline across the
"mouth" of the "river")

and

https://www.openstreetmap.org/relation/3474227 (the "river")

This current representation in OSM leads to a few strange situations
especially in toolchains/map styles that use different colours for
inland water and oceans, or that draw sea depths, or just highlight the
coastline. Buenos Aires, according to OSM, is currently not a coastal city.

One of the involved mappers who aligned the coastline more closely with
the coast wrote (https://www.openstreetmap.org/changeset/79201390) "I
believe this is inline with guidance
(https://wiki.openstreetmap.org/wiki/Tag:natural=coastline)".

I'm not so clear about how to interpret the wiki page myself when it
comes to river mouths. There's a clarifying proposal here
https://wiki.openstreetmap.org/wiki/Proposed_Features/Coastline-River_transit_placement
but this is still at the proposal stage.

Opinions?

Bye
Frederik
