The alignment change of the expressway introduced in this edit was generally bad, and has had to be reverted.

Please don't make clearly incorrect additions like connecting a driveway to an elevated expressway.

This was a bad edit which added streets that clearly did not exist. Reverted.

Hi. The addition of barrier=city_wall to the entire street was not the correct way to address this. If you want to add a barrier tag, place it on a node where the barrier is, and use a more appropriate tag such as barrier=block. In this case, though, the entire street is being redeveloped, so it should just have been deleted and the area tagged as landuse=construction.

This edit, along with changeset/93155272, messed up the geometry of the entire area, and has been reverted.

Like changeset/90897318, most of the changes in this edit introduced bad misalignment; I have reverted most of them in changeset/93339636.

I have determined that this edit hardly contained any good changes, and have reverted most of it (except for a few street additions) in changeset/93339636.

The addition of this rectangle way/727084775 appears to be a mistake, so I have deleted it.

I've partially reverted this changeset, as it introduced bad alignment.

It's unnecessary and redundant to add sidewalks as separate ways when the road is already tagged with sidewalk=left, as Chaeng Watthana Road already is.

I've reverted the moving of the expressway in changeset/93333656.

In this edit, you shifted the position of the entire the expressway object, resulting in poor geometry away from the main area you were editing. In addition to relying on misaligned imagery (as mentioned at changeset/91793091 ), you also didn't appear to account for parallax: If you're editing an elevated expressway, you must align the road with the base of the pillars, not the direct appearance of the road in the imagery, which will appear shifted due to the camera angle.

You seem to be relying on Maxar imagery, which is misaligned in the area. Please remember to always check alignment with GPS traces. I suggest revising the edit. Please also make sure not to leave weird kinks as has happened here with Pracha Chuen Road.

This edit also introduced bad offset, as mentioned at changeset/90897318

This edit introduced a LOT of misalignment of features which were previously accurate. You seem to be relying on Maxar imagery, which is misaligned in the area. Please check alignment with GPS traces, and if you're not sure, avoid making such large-scale changes. Please move the streets back to where they were previously.

Let's wait a bit for further input. These appear to be village whose names aren't otherwise mapped, and it would be beneficial to retain the information in some format.

Also, the area around way/845569064 has been fenced off for construction. It's not accessible, and shouldn't have been created.

This edit introduced bad connections to ways 818107475 and others in the Outdoor Parking 5 area. See before (top) / after (bottom): https://imgur.com/a/pkMFjxb . There clearly is a covered walkway going through the parking lot in the more recent Maxar imagery. I have reverted the change, but please be more careful in the future. Thanks.

The highway=residential tagging of the road bridge going into Mega Bangna has been raised at https://github.com/GRABOSM/Grab-Data/issues/51 I've suggested it be changed back to highway=service.

Actually, I was referring to the addition of layer=1 to way/221177327 and way/221177328, which shouldn't have been done. (The ways also had improper bridge=yes tags, which have been removed). Sorry for not having been more specific; I wasn't sure if you were still active.

But your reasoning regarding the split of the viaduct is also incorrect. It is perfectly fine to tag the entire viaduct as layer=2, as doing so won't cause any conflicts with other crossings. Splitting it as you have done was not wrong, but is unnecessary.
