<p>Hi,</p>

<p>pleasse see this way:</p>

<br>
</p>
<p>It was changed more than 3 days ago and the change is not
rendered.</p>
<p>I understand that coastline ways are special, but that seems
too long for me.</p>
<p>Any hints why this takes so longĀ ?</p>

Hi Gerd,<br>
<br>
This part of the coastline of 3.3 km consists from 238 nodes. It is
not too much yet. Sometimes I meet a small lake which could be seven
hundred nodes.<br>
<br>
In JOSM there is a tool SHIFT+Y (Simplify Way). After Simplify Way
the same 3.3 km would be just 102 nodes. <br>
<br>
I did not change this particular coastline. But usually when I see
too many nodes (in my opinion) for a way in JOSM, I make SHIFT+Y and
then add some more nodes to adjust the shape. I do not know if it is
the right way, but I think that too large number of nodes could be a
heavy load for the database and for the rendering program.<br>
<br>
On the other hand, I am in doubt, - perhaps, people invested a lot
of time and labor in clicking these hundreds and hundreds of nodes,
to make a nice looking map, and I am not sure if I am doing the
right thing with the tool SHIFT+Y (Simplify Way). Maybe this
excessive number of nodes is negligible for the database and
rendering?<br>
<br>
Still this tool, SHIFT+Y (Simplify Way), exists. And it also could
be that a large quantity of nodes is created automatically by some
image recognition AI program, or from a GPS trace, and a user was
just not aware of this tool.<br>
<br>
With best regards,<br>
Oleksiy<br>
