Hi, don't forget to delete the drawing aid ways when you finished the railway.

I think the airport wasn't adjusted when i updated the golf course, instead of the other way around. The difference between what land belongs to the airport and what belongs to the gold course is not 100% clear since it serves as a military base with recreational facilities too. The angle at 21.03484,105.89483 should probably be glued to the golf course though.

Hi, I would recommend to draw a line (or preferably even 2 parallel lines [SHIFT+P tool]) and tag them with highway=construction + construction=motorway. This allows it to be easily upgraded once the road is completed.

I'm not really sure to be honest.

All I could find now is that they are planning to construct S204 between Wuchuan and Zhennan (See #1287 http://www.guizhou.gov.cn/zwgk/zdlyxx/zdxmjs/zdxmmd_31707/201811/t20181107_1896006.html; osm.org/directions?engine=fossgis_osrm_car&route=28.5663%2C107.8957%3B28.7015%2C107.8715#map=12/28.5746/107.9427) which is to the west. They do change up the highway refs a fair bit recently due to the 2013 New Highway Plan where a lot of new G roads supersede the S roads. If you have any better clue, feel free to change it.

Hello,
I only removed 'name=' tags in this changeset, the tertiary designation was done by someone else.

兰新铁路有什么问题？

I had some PM contact with the user, i will forward it to you

in osm.org/changeset/63592417 someone deleted lots of reservoirs that were added by you and other from SWBD or other lower resolution sourced. I have attempted to revert that changeset in this changeset. Is there anything still wrong with it?

And load in JOSM, select all and change tags

It should be fixed in this changeset osm.org/changeset/77490578

Yes you are right, I think they were under construction at the time so I guessed it was wind based on the high locations, I will correct it.

谢谢 我修正了

Thanks for the notice, I've just corrected it. 2 years ago we didn't have any high-res coverage in this area. But yes, you can't really tell the difference:
https://apps.sentinel-hub.com/sentinel-playground/?source=S2&lat=23.060937774355214&lng=103.15316677093506&zoom=15&preset=1-NATURAL-COLOR&layers=B01,B02,B03&maxcc=20&gain=1.0&gamma=1.0&time=2019-04-01%7C2019-10-31&atmFilter=&showDates=false

I've come to be more cautious with tagging based solely on Sentinel-2.

Alright I will let you handle it then!

Ok seems like the recent changesets are actually legit, so I will revert just the bad changesets

I will notify DWG because there are many similar incorrect changesets by this user.

啊你对的。谢你修了。
