<p>Hi,
<br>
<br>
Tagging seas as multipolygon has good benefits some renderers but
the name of the sea in any viewed part of this sea. So you are not
compelled to navigate the middle of the sea to know his name.
This is an easy process for the renderer it looks up for a sea
relation where the coastline is member of it and put the name from
the relation on the right side of coastline.
<br>
<br>
But when there are difficulties of large sea I suggest new key for
coastline will named "sea_label" this key must refer to the node
id of the sea so the renderer will get main of benefits of sea
relation. With less maintain and less DWG headache.
<br>
<br>
Someone may say it may be difficult to beginner users to get sea
node id but editors can put all nearby sea in a drop down menu to
easy selecting as they translate most key values to user language.
<br>
</p>
<p>I send this massage also to tagging mail list.<br>

<div>Hello,<br>
</div>
<div>I actually thought about creating a
multipolygon for Black Sea, for helping to data
consumers and therefore visualizing more easily
by creating a multipolygon for Black Sea, which
is currently tagged as a node at <a target="_blank" href="https://www.openstreetmap.org/node/7015642404" rel="noopener noreferrer" moz-do-not-send="true">https://www.openstreetmap.org/node/7015642404</a><br>
</div>
</div>
</div>
<div><br>
</div>
</div>
<div>I think this can be done very easily, like the one
for <a target="_blank" href="https://www.openstreetmap.org/relation/3987743" rel="noopener noreferrer" moz-do-not-send="true">Caspian
Sea</a> or <a target="_blank" href="https://www.openstreetmap.org/relation/4594226" rel="noopener noreferrer" moz-do-not-send="true">Aegean
Sea</a>. About naming, I am going to follow the same
convention done at Caspian Sea: putting a name that
encompasses all of the official languages of countries
neighbouring to Black Sea. About the complexity of
multipolygon, I think it will not be more complex than
the Aegean Sea or the Caspian Sea. Also, while
uploading, I am going to divide the upload to chunks
via JOSM. <br>
</div>
<div><br>
</div>
</div>
<div>The reasons for writing that to talk mailinglist is
getting input from the community about whether the
multipolygon should be created or not as the
multipolygon covers a big area, or should I do any kind
of corrections while uploading.<br>
</div>
<div><br>
</div>
<div> Feedback is very much appreciated.<br>
