Hi FF0x, I have found your recent edits on Ilhabela in Brazil where you have changed the name of the island from "Ilha de São Sebastião" to "Ilhabela". Based on my research, the approved name for this island seems to be "Ilha de São Sebastião" and "Ilhabela” seems to be the name of this archipelago. Let me know if you agree, and if so I’d like to add the place=archipalago tag to www.openstreetmap.org/relation/298379 (which is already named Ilhabela) and change the tag on this island (relation/2021025) back to name=Ilha de São Sebastião. Let me know what you think, Happy Mapping!

Hi pasukanoren, Thank you for bringing this to my attention, I reviewed this island again and realize the update I made from GEOnet Names Server is not spelled correctly. I'll change the name back to "Pulau Miangas" as before. Happy Mapping!

Hi mariotomo, thanks for the comment. I reviewed this area again and see that I originally aligned the coastline around some vegetation which is partially underwater. I can update it back to the previous alignment. I understand you are also talking to Andrew on Telegram.

Hi 弥太郎, thanks for contributing to OSM! I wanted to reach out about this changeset which caused the Kuril Islands archipelago to be submerged by water after you added the natural=water tag to relation/7273443. I removed this tag since it flooded the whole chain of islands, if you have any questions or need further guidance you can visit osm.wiki/Beginners%27_guide. Happy mapping!

Japanese translation:
こんにちは弥太郎、OSMに貢献してくれてありがとう！ relation/7273443にnatural = waterタグを追加した後、千島列島が水に沈む原因となったこのチェンジセットについて連絡したいと思いました。 このタグは島のチェーン全体に溢れているため削除しました。質問がある場合やさらにガイダンスが必要な場合は、https：//wiki.openstreetmap.org/wiki/Beginners%27_guideにアクセスしてください。 ハッピーマッピング！

Hi Vinber, thanks for notifying me of this! I agree that this is too large and will try to avoid this kind of changeset upload.

Okay. I have realigned this area to account for more of the beach being represented here. I appreciate you reaching out and providing some local context for this situation.

Thanks for getting back! Since the variation in tide is so drastic do you think it’s more representative to pull the coastline feature down further to a better average tide level between low and high tide?

Hi Pt873, thanks for reaching out. In an effort to create better topology between the beach and coastline I merged the shared boundaries together at the mean high spring water level where the coastline is mapped.

Hi gbragaalves, thanks for reaching out!

Looks like the park and forest feature were accidentally copied and pasted here, I’ve removed them.
