这样的对象有什么意思？

Hi, can you tell me what the source is for the proposed expressway you added? Because on the satellite image it is at a different place, but your edits look very detailed too.

I think only this expressway can be there http://news.dayoo.com/guangzhou/201811/20/152263_52366826.htm

商合杭高铁直到2020年在建。保持railway=construction!

好、我会还原 👍

Unfortunately that seemed to be the case in the majority of cases, please check each object on a case by case basis the next time.

Same story here: osm.org/way/543289819#map=15/31.2686/104.4541

Did you add oneway=yes to all motorway links?

Look at this one for example: osm.org/way/466509759#map=18/31.24056/104.43108

It's used for both directions of traffic, it should have oneway=no, oneway=yes breaks the routing.

If you don't know what it is, please try to contact the person who last edited it, instead of tagging it wrong.

Hi, I'm aware of this tag and I try to use it, but sometimes I forget. Actually I thought I was one of the few using it myself as I've never come across any correctly tagged oxbows.

Yes it's new, I traced it from Sentinel-2 but you can verify it's there on Google Maps too.

Why did you delete it? It was closed down?

请用landuse=residential而不是building=yes
osm.wiki/Tag:landuse%3Dresidential
因为building=yes是为了单个大楼

It was part of a changeset deleting many other object, but after discussion it will be changed back.

Why did you delete the lakes without retracing them? They are not incorrect, just crudely drawn.

If you make parallel ways in JOSM, use the parallel ways tool to keep the same distance between both roads even in bends.

This changeset and most of your other changesets in China also wrongly change motorways into trunk or primary roads. Did you visually check your edits? The difference between a primary road and a motorway should be very clear on imagery, and if you took the time to read the wiki page carefully, or look at the names (even where the name:en tag clearly said expressway, you changed some into other types), you wouldn't have made these mistakes.

I will try to revert the wrong changes. I hope you didn't make the same errors in other countries, because it can take some effort to clean it up.

I get that you are also trying to improve the map, but changing stuff without checking carefully can easily result in errors.

Did you add the name here? osm.org/way/576429094

高速公路 means expressway, so it must be an error

Alright. Next time, you can translate the name, it would translate to XXX Expressway, and then it would be clear :)

Why did you change a motorway to a primary road?
