Why do you edit coastlines while you don't know how...?

First of all coastline MUST be a closed line and thus you either have to leave it as is or to tag the whole river as coastline which is much more complex since you have to both edit the river relation _and_ to add coastline tag to islands... Hence it is common use of tagging the coastline at the border between river and sea/ocean.
You are free to remove the coastline tag again _IF_ you add the coastline tag to the whole river... have fun...

Hi Gescriey,
just for your information. The coastline update process has stopped because of a bigger edit at antarctica. I've informed the talk-list and hope that someone will take care of it...
You can follow the discussion here: https://lists.openstreetmap.org/pipermail/talk/2022-January/087193.html

Hi Gescriey,
it's because coastline tags are not allowed for relations. They are on the enclosing way of the islands itself, which is correct.
The reason, why it is (yet) not rendered correctly is that the tag was added at 24th and these changes may take several days to appear on the map. So my advice would be to simply wait a few more days...

I simply don't know a better way of tagging this correctly. The problem is, that both bare_rock and coastline use the natural key. And the only way of using this both is a MP. Since this existing island was not visible on the map, I added the coastline. As coastline must be tagged on the way, the bare_rock goes to the MP. If you know a better way, please let me know.

Well roared lion! If you think you can fix it a better way, than simply do it!!

May be, but a relation as coastline is more wrong. I did only fix that and took tagging out of history. If you have local knowledge, then you are free to fix it!

Direction of coastline is always land on left hand side!

Erstere Frage kann eigentlich nur jemand von der lokalen Verwaltung beantworten.Ggf. ist der dazugehörige "B-Plan" öffentlich und kann eingesehen werden.

Zweite Frage... keine Ahnung...

Please do NOT define new coastlines over existing ones!
I will now delete ALL of them!

Please have a look to the change of benoitdd...

Hi Colin, maybe you didn't look close enough to what I changed... I only changed the direction of an already defined coastline which was wrong...

This island is not visible on any aerial image. Please proof its existance!

This island is not visible on any aerial image. Please proof its existance! Which "map" did you use? Did you check the copyright?

I've just looked more closely to the aerial image and it could be that the area between the island is intermittend water. If that is the case then the island are _not_ connected... But that can not be decided due to the aerial images, only a local can know this...

Hi SnailMiner. OK, sorry for beeing harsh... The area is still not rendered correctly (because of the rendering delay), but I think it will at least beeing rendered with the not mapped gap in a few days. I would suggest to wait until this happens. After that I would offer my help to "fix" the gap... The correct mapping would have been how I did it. The coastline should enclose the whole land area, while the separate islands then would go into two separate multipolygone relations.

Overlapping coastlines are WRONG! Please fix! I will NOT fix it again! The render will also NOT render this correctly... It was correct until you "fixed" it. Remember that coastline edits take _days_ to go through the renderer...
Most likely some other coastline reviewer will fix this in a few days... if you don't...

Hallo Jochen, bitte "natural=coastline" auf die Linien platzieren und nicht in die Relation.

You are creating bad coastlines over and over again! I meanwhile count that as VANDALISM! STOP THAT! Otherwise I will be forced to send a message to the OSM foundation.

You (again) created overlapping coastlines... And WHY did you delete the island relation for Idö? And WHY did you again placed a "place=island" on the line for "Brunnskär" (it is already in the relation!)? And WHY "area=yes"??? It's useless! Please LEARN! Or stop editing...
