Không nên lạm dụng đổi các đường thành primary!
Bạn hãy xem cách thành phố San Francisco, Mỹ phân loại các đường. Cả khu vực trung tâm thành phố cũng chỉ có vài ba đường được đánh là primary, còn đa số đều là secondary hết.

Construction of this expressway hasn’t even begun yet. What’s the reason for keep setting it to “construction”?

Sửa như vậy là đâu có đúng. Mấy đơn vị hành chính đô thị đều có 2 phần thể hiện trên bản đồ này. Một cái node để thể hiện trung tâm hành chính, và một relation để thể hiện địa giới hành chính.

Cái node trung tâm hành chính chỉ để đúng tên chứ không thêm tiền tố "Thị Xã" hay "Thành Phố" gì hết. Ví dụ node trung tâm của TP Quảng Ngãi chỉ là "Quảng Ngãi", hay của Đà Nẵng chỉ đơn giản là "Đà Nẵng" chứ đâu phải "Thành Phố Đà Nẵng". Mong bạn lưu tâm vấn đề này. Xin cảm ơn!

Hi there! Would you mind explaining what's the point this overlapping relation "Phường Tân Quy" because there has already been one. Your newly created one also has poorer quality so I would suggest that you stop creating such objects again unless there's a really good reason to do that (which I am willing to hear if there is one).

Mấy cái node tên đô thị chỉ để đúng tên của thành phố/thị xã/thị trấn đó thôi. Node "Cần Thơ" đâu có để "Thành phố Cần Thơ" đâu, thì bạn sửa thành "Thành phố Vĩnh Long" làm gì để cho nó cá biệt vậy?

Đề nghị bạn xem xét kỹ lưỡng khi chỉnh sửa.

Vấn đề mấy chữ Đăk/Đắk này tôi nghĩ địa phương họ viết sao thì mình cứ viết vậy. Ở Kon Tum họ không thêm dấu sắc, nên viết là "Đăk", còn Đắk Lắk, Đắk Nông thì có dấu sắc. Thổ ngữ mỗi vùng miền khác nhau, ở Lâm Đồng thì chữ Đăk/Đắk này là Đa/Đạ. Cũng giống như Cư/Chư vậy, Đắk Lắk thì viết là "Cư" còn Gia Lai, Kon Tum thì là "Chư". Hay Ea/Ia nữa.

The Prenn Pass is no longer part of the National Route system, and thus cannot be classified as trunk road anymore. Please don’t make such changes again. Thanks!

Google Maps is not 100% correct about Vietnamese geographical features' names, so please do not rely solely on it. Please also use information from the documents "Thông tư ban hành Danh mục địa danh dân cư, sơn văn, thủy văn, kinh tế - xã hội phục vụ công tác thành lập bản đồ tỉnh XX" by the Ministry of Natural Resources and Environment of Vietnam (Bộ Tài nguyên Môi trường). Thanks!

Only the upstream section of this river is named "Sông Pha", the downstream section to the confluence with Sông Cái is named "Sông Ông". https://thuvienphapluat.vn/van-ban/Tai-nguyen-Moi-truong/Thong-tu-33-2015-TT-BTNMT-Danh-muc-dia-danh-dan-cu-son-van-thuy-van-kinh-te-xa-hoi-Ninh-Thuan-287264.aspx

Please resolve unclosed/broken multipolygons before you commit your edit!

It's completely normal for some maps to be outdated. The Decree 4155/QĐ-BGTVT has been proved to exist, and actually took effect therefore we should base on that.

And when is the date of that Decree 1555/QĐ-TTg? It's 28/6/2016, which is before the date of the Decree 4155/QĐ-BGTVT (26/12/2016). Also, these maps are from the Ministry of Construction (Bộ Xây dựng).

Very simple rule:
If a road is part of a National Route system (quốc lộ), then the Ministry of Transportation (Bộ Giao thông vận tải) is responsible for managing it, so any road upgrade will be done by the ministry. If it is a local road then either the People Committee (Ủy ban nhân dân) or Department of Transportation (Sở GTVT tỉnh) is responsible for its update.

In 2011-2015, the Ministry has upgraded the whole route of Dầu Giây to Dalat (including the Prenn Pass), but the recent upgrade in 2023 was done by the government of Lâm Đồng province. Isn't that clear?

No one is guessing here. Just take a look at this link: https://quochoi.vn/bandannguyen/cutriQH14/Pages/Home.aspx?ItemID=33149

The Vietnam Ministry of Transport has decided to reroute QL.20 to Mimosa Pass in 2016. If it was still part of the National Route, the Ministry would be responsible for its recent upgrade, not the government of Lam Dong Province.

Then simply mapping those “public work” objects and name them is perfectly enough. Drawing them as place nodes is wrong because they no longer exist administratively as place names. Adding those place names as labels of several wards creates a worse mess.

Please stop adding place names that no longer exist. You are creating a very huge mess.

PeakAdvisor grab data from many sources, one of which is OSM. If you look at the peak next to “Anh Na”, it’s named “Pol Li”. Both of these are the results of vandalism by the same one user 4 years ago (and I’m currently suspecting that you are that person too), but no one recognized. PeakAdvisor grabbed that erroneous version.

Can you provide a source that indicate that "Anh Na" is this mountain's name? Otherwise this is very apparent that this is vandalism.

Well! So I don't even have the right to watch out and see if my previous edits have been vandalized. I was drawing it according to the sources by the government, which took me 5 days, while you are applying your "local knowledge". And yes, this will be my LAST WARNING. Either you revert it yourself or I will report this to the admins.

So now you are apply your "personal knowledge"? What do you know about the "de facto control"? I mapped it according to sources by the governments? And now you are completely messing it up.
