All done ... I think was where I split the road and there were two errors ... anyway fixed now (again, I hope).
Cheers

Apologies, yes it should have just been a note to explain why I changed the main route after riding through it. It was not obvious on the aerial photos then.
I have removed the note, and changed to residential hwy, along with tracing/updating a few more roads in the area now the aerial pic quality is better. Cheers.

Please will you respect local mappers and stop changing U turns between two primary roads, into residential or unclassified.
You have done this all over Chiang Mai, in the interests of Grab ! Why???
It just pisses us off. We change when we find, but hope you will go back and revert where you remember you have done this.

Dear user "leaf_hostel" ... Is there any reason you created an OSM account, just to change your hostel into a park ??
It's a building, and you occupy just one end .... by no stretch of the imagination is this a park.
If you dont revert in a few days, I will.
OSM is not a site for advertising purposes, al;though thsi beats me in what you were trying to achieve.
Russ.

Dear Tim,
Please can you explain why you deleted the roundabout I had created at this junction near Bouamphieng. It took me a long time to plot using my GPS after it was re-constructed in late 2018 as a roundabout. Clearly you have not been there recently.
I presume you looked at the map image, and did not bother to check that it was older than my edit. You did not have the courtesy to write and ask me first either.
Please change it back to the way I had it.
Russ.

Johhny,
I have read the discussion and as I have said many times before, I will continue to tag roads in gated communities as living_streets. While the legal definition may not exist in Thailand, they share the same similarities with their European counterparts, and that's how I tag.
There are many instances in Thailand where we tag on similarities to European roads, even though the legal definition does not exist. For example, take the Eastern outer ring road in BKK.... its a ring road, perhaps an expressway, but not a legal motorway in Thai parlance ... but yet we tag it as one, because of its similarities to a European motorway.
Any changes of my edits without a substantiating note, will be changed back by me, again. I hope I have made my point.

Way: 642032937 - Mr Ram, you have drawn this service road, but to my eyes, it does not connect to the ชม.2025. I can clearly see a fence. In fact, I'm surprised you even saw a road there. Please review and correct.

Way: 643310645 - Dear juvvanapudi_1, why are you taking the time to add bridges over waterways on major highways, when local mappers have already drawn these waterways as passing under the highways in culverts (the tunnel tag) ?
You are wasting your employers time, but also adding bridges where they don't exist!
Please refrain from this incorrect practice. I have now corrected your poor work.

Way: 641453900 - Dear sra_vya ... I'm just wondering why you drew this road through the hotel lobby, across the roof of three houses then right through a wall we have plotted.
I have looked at al the aerials we can see, and can see no evidence of a road. If you were not so lazy and added a source, it might give me a clue where to look for this road.
Or again is it another example of you making up streets to justify your job ?
I would greatly appreciate a reply being as you ignored most other comments I made.

Dear sra_vya,
Im sure you consider your work from Grab very important, but over here we tag U-turns as links. This includes where they also access side streets. Its not a residential road - do you see any houses ??
So why the hell do you think you should just come in and modify them all, completely when Mudmala comes in and changes it back, then you change again. You clowns work for the same company !!... are you just doing this so as you can charge Grab more for Global logic's work?
I have changed it back AGAIN so please leave our frigging Thai map alone. Go back to playing your tennikoit where you do less harm.

Dear renuka1 working for Grab ... this is a tertiary road, with a CM prefix. It takes us local mappers a lot of hard work to find these roads numbers out, then we correctly map as in our Wiki.
You jokers at Global logic come along and just change stuff for the hell of it. Please tell me your reasoning behind changing the tag to an unclassified road, when the damn road has a bloody classification. Are you a damn moron or just want to piss us off over here... either way I cant see how you are helping Grab by reducing the status of good roads, perhaps making taxis take longer routes !
I have changed it back, now don't mess with any more.

Dear renuka1 working for Grab ... why have you changed way/204365638 from its correct status of a primary link road (which how we tag U-turns in Thailand) to a Service road.
Why do think that changing roads helps Grab ?
Its quite possible that routing software will ignore this U-turn and send the taxi to the next Primary U-turn link, which would be both stupid and wrong.
Why cant you just leave the Thai map alone instead of trying to convince Grab you are making useful changes for them.
I have changed it back, now leave it alone !

Way: 641104666 is another way that has been imagined by the Global logic dreamers. Its a bare patch of ground that serves as access to private properties and it is closed off by a fence at the NW end. I pity the poor Grab drivers that rely on this crap mapping. I have changed to a private track to at least stop it getting added again !

Please also confirm its not one way.

Way: 488477944
Bank, you have added this way, but not connecting at the Eastern end so no GPS would use it. I fixed for you now.

Way: 653314857 - There is no track here. If its a proposed road, or one under construction, please tag accordingly.
I have removed it.

Way: 559552127 - Dear Jon from Grand Junction. Ironic as junctions are not your forte, and you have been pretty lazy plotting this junction.
I mean, just look at the poor accuracy of the tertiary ลย.3015 which we did many years ago when all we had was low res aerials. So you come along with your fancy machine learning, plot the residential perfectly, but are just to damn lazy to give us a few minutes of your time to add a few extra nodes to the Tertiary road, and make the junction come a bit closer to looking like it does in real life.
But I suppose with no more edits for three months, my comments fall on stony ground?
Russ.

Wittawat -
Regarding Way: 657317377, you have to stop editing until you learn more about OSM. It look like you deleted a valid road, then added a simple line (way) without adding any tags. This will destroy the map as it wont show up on any map. Please contact me if you don't understand.
I have already written to you separately about adding buildings with just an area tag. These also wont show up.
Russ

Hi Natchaya - its great to see you tracing buildings and adding to the map, but if you don't use the building tag, nothing will get rendered. More details can be read at building=house
Thanks, Russ.

Jeff, Thanks for the reply presumably on behalf of Sam.
The pedestrian connection on the one node is arguable, so I would not add it. But even so, the 7 other points that were connected as roads clearly do not go through.
You may feel that when adding data in the bulk manner in which you did, mistakes are easy to make - well thats my whole point. And quite frankly, you have left us with thousands of these. Can you confirm if your team are still correcting or has your project been wound up ?
Rgds, Russ.
