all imagery I saw, also after your edit date hint that UOB is still a bank, not a cafe. Can't be certain that I saw all imagery, as Mapillary is very crowded that area. But even our competition imagery has no hint of cafe. Please double-check

these mapped trees do not match up with aerial imagery. Please give details on how you derived the position of trees

great. These water features had been created 12 years ago, based on Landsat imagery, which at that point was also a bit older already. Water line might have changed over the years and Maxar imagery provides much higher resolution. Cross-check alignment of imagery against GPS tracks before doing large-scale changes to avoid the need of another round of corrections later.

I fixed a lot of spelling mistakes. It is Soi, not Choi. ซอย

Certainly no clinic. Maybe a doctor's office? please confirm what this is supposed to be.

Thank you for double-checking this edit.
I also checked this relation and it looks technically OK. Somewhere in the database update process this change triggered osm2pgsql to delete the relation from the database. My initial guess was that the geometry was no longer valid and this triggered it to be deleted on update. But I found no obvious mistake. There are no gaps, the way direction is all in the same direction and outer roles are set. I sent a mails to the developer list, maybe there are some ideas. Probably this will lead to a debugging session of the involved software stack.

I am uncertain what exactly happened, but after your edit the boundary relation disappeared from my extract database. Rendering shows a gap at the ways you added in relation/2067731:
https://thaimap.osm-tools.org/?zoom=14&lat=20.36553&lon=99.47434&layers=BT

Can you spot something wrong?

Could you please give details where exactly your business is? What kind of business is it?

what do you mean with fixme comment on Pa Phai Nuea Soi 3? ป่าไผ่ เหนือซอย 3 (77658212, v7)

Shouldn't it be Soi? ซอย?

Thanks for confirming the ground survey. I worried the detail was somehow deducted from aerial imagery. There are still macadam roads around which are just compacted gravel. So well possible.

I meanwhile found the related mapillary imagery. Looks like compacted gravel, macadam surface

Can you please give a source why this small section of road supposed to be unpaved in the middle of all paved roads? way/700017741

had you been there on survey? Road surface looks more like concrete. Please confirm unpaved surface added in this area

I understand the classification. But what was your source of these roughly 100 places you added or modified? Did you copy them from some database? In OSM we care very much that the license permits us to do so. This is one fundamental pillar.

what is your source to tag Cheong Doi as Town? Or others?

I understand that you like the way your parking lots are rendered. But comparing them with different imagery sources hints, that they are not nearly as accurate as they appear now. Better avoid "mapping for the renderer", just to have something look nice on the "default" map.

Sorry, just noticed the source tag was not touched by you. I leave it to the local community to decide what to do with them: https://forum.openstreetmap.org/viewtopic.php?id=72291

so not exist, like others. Do you think this is funny?

I fixed it. One way had a wrong direction and the ways had been on wrong position in both relations, so they did not form a closed loop.
