Hallo Svalbard, ja, das tun sie. Ich war beim Bismarckturm. Passt etwas nicht?

Seit wann ist Meinersen eine Stadt?

It seems, that there is in fact a construction area and thus I've now fixed this. Hope, it is okay...
Very sad, that the original author did not react...

Revision...
Corrected way direction...

No, the direction of the way is correct (Land is on left hand side)!
I would currently not remove the coastline tag, because it "might" be correct... Problem is, that it is not visible on aerial images right now!
Thus, I think that only a local can solve this problem...
If the (initial) editor/mapper does not react on this discussion, than it "might" also be legal to remove the coastline tag on the new area, but currently I would prefer to not do this!
It seams, that coastline update process is broken anyway currently... See
https://osmdata.openstreetmap.de/data/coastlines.html

Overlapping coastlines is not valid!
Coastline checkers (like mine) will detect it.
Since I cannot see the construction area on any imagery service (even not on Maxar Premium!) I cannot fix it.
So, it most likely is up to you to fix it...

(If not fixed) You will see the error tomorrow at noon UTC here:

Sorry...
Hat sich geklärt...
Ist ja in der Relation...

Okay, aber warum hast du Namen und Wikidata-Code gelöscht?
Ggf. auch den referenzierten Artikel bei Wikipedia als Attribut angeben...

Yes, I know, but it was not my changeset which destroyed the "heath" relation (#10901513). I just repaired the coastline part and removed a doubled way from that relation...
Since I am not a local I cannot say, how to fix this.
Putting the "heath" to the coastline way is wrong because it is not a closed line...

Hi!
Basically I think, you are right for way #4144152.
The problem is the enclosing way (e.g. way #554743433) which is also tagged as coastline which seems to be wrong.
Can you please also fix this?
Technically coastline may not defined inside coastline...
Greetings, Andre

Hi asibwene,
please, please, LEARN, that coastlines have very special rules!
If you continue to ignore them I will be forced to count your edits as vandalism!

Please learn, that for coastlines land must be always on left hand side.
See Wiki for more details.

Please do not add coastline tag to relations as it is only allowed for ways.
See WIKI: natural=coastline

Please learn, that the coastline tag surrounds dry land! Read WIKI for more info. coastline is defined as the line of HIGH TIDE water. And wetland is flooded sometimes...

Please _never_ leave coastlines uncompleted! And please learn that coastlines are at high tide line! See osm.wiki/Coastline
Because of too much damage I now reverted this changeset. Please be more accurate next time...

Please finish your work as the coastline is now not okay. Each land area should get its own coastline. Also learn that coastline is high tide line! Read this: osm.wiki/Coastline

If this route is really disused than go ahead and mark it as disused... But marking it as coastline was definitely wrong and since the mapper was a newby this very much looked as a bad try.

Please learn that land MUST be on left hand side for coastlines.

Please don't remote the coastline tag unless you define a new one. Coastlines MUST be closed and there may be no gaps...

I did some technical fixes, but...
Are the new coastlines really "high water level"? See wiki: osm.wiki/Coastline
