Hi,
Unfortunately for us, we lost Maxar after Facebook had finished its automated edits of the Country and only have Bing at present. You are right, it was the best.
I do leave note tags when appropriate, but I am not familiar with the comment function you mention. Is this a feature of the editor, given I use Potlatch2 ?
Rgds.

Hello Jay - My tone is one born out of frustration, so apologies if it sounded harsh. Your intent to lead traffic out of the cities, should not cause you to change the status of roads. This can be achieved to a certain degree by adding the correct speed limits and not changing the classification tag.
Examples of incorrect U-turn tags were not as prevalent as I initially thought but in changing the "ring road" to Secondary, you did leave some of the U-turns as Tertiary_links, which is not really correct. They should match the parent roads they link.
I note your analogy to the M25, but that's not the case here. Our wiki at osm.wiki/WikiProject_Thailand asks that you tag according to current road numbering with respect to 3 and 4 digit National Highways getting Primary & Secondary status, while a Provincial prefix warrants Tertiary.
But even then, you chose not to contact me, or search on the Thai user forum, but just make the changes.
I ride this road to Udon on a regular basis, and I can assure you that the "bypass" was built to facilitate access to Government Offices under construction, rather than a way around the centre - the current Highway even with its traffic lights, does that job admirably.
And with regard to satellite images, Thailand has poor and outdated imagery, and if you are moving roads back to suit the image, please don't. We have a number of major roads now completed, that just don't appear on the imagery, the Chiang Rai & Chiang Saen bypasses perhaps being the most notable.
So, I will finish by apologising of my tone was not right, but I expect Im older than you at 60, and ridden/mapped through a damn sight more countries .... my point remains unchanged ... please don't change road status in Thailand just because you think traffic should go another way.
There will always be exceptions, and we are still reeling from the damage done my Kaart and Grab (taxi), changing roads to suit their beliefs. You are welcome to challenge anything but would invite you to join our forum and explain why first.
Rgds, Russ.

And you have changed the unclassified frontage roads to primary_links on one side of the Hwy 210, but not on the other.
Any rationale, or just tradie work ?
Frontage roads are for local traffic to access shops, and not for caars to fly down at exit ramp speeds. That's why we tag them this way !

Furthermore, I see you cud not even be bothered to change the U-turns and links to match the new status. All this does is add to workload when we run error checking programs. May I ask where else you have been arbitrarily changing roads in Thailand ?

Jay - please respect local Thai mapping guidelines for the status of roads. We have a Wiki that explains this.
You have changed the Rural roads around Nong Bua Lam Phu to Primary, while downgrading the main Hwy 201 to secondary. I can only assume this is a misguided attempt to force traffic around the city. I am manually reverting the change today, and would ask that if you disagree with local mapping convention, you have the decency to join the Thai forum and put your case across.
I'm guessing you dont live here ... we do, so please refrain from trashing our work in this manner. Russ.

Dave, I took the road ref 4070 from the DRR roadnet database, and assumed it truncated the 3065 at 18.36867 98.9052.
The 3065 is not on the database so may be due for downgrading. The problem we have is not knowing whether the database is more up to date than the signs on the ground !
I have not been there in person but was adding data from Colin Scullion who went there in Dec 2019. He confirmed the 3065 was paved all the way to the end, but was not explicit enough for me to use that ref to the end. If you want to change to whats actually on the ground now, thats OK with me. Cheers.

Please stop editing our Map - you have deleted the Highway tag from road ฉช.4008. You either don't know what you are doing or you are destroying data on purpose. STOP NOW.

To the mapper that changed this new road (ชร.1063) from construction status to an open highway, thanks for your efforts.
However, I presume you do not have much OSM experience and its simply not good enough to cut through the existing small roads, leaving them all connected. Physically, I checked these areas yesterday, and unless there is a U-turn drawn in, then a concrete ditch and/or Armco barrier prevents through passage on the minor road (or track).
I have fixed this now, but please be aware of this common mistake when mapping.

Dear Mr Baldmaster Caleb @ Kaart : Mapping may give you a feeling of joy as you put it, but over here it brings nothing but despair....
Way: Klong Chonprathan Road (697847756) is one of many you have added where in your pedantic way to chop up the main highways to give them lane and turn information, you have created new segments of road with no relation info carried on through.
So if you look at this segment and the one below it, & if you understand OSM, you will see the road 121 relationship has now been lost for the sections you added.
I urge you to refrain from editing ways such as major highways until you have learned more about OSM. If you concentrate on tracing cornfields closer to Provo, then you won't cause so much despair in Chiang Mai.

Dear Te-Ika /Daniel @Kaart ... way/94054580 carries the road ref ชม.4307. It ;eads to a monastery. There are very few residential houses along it. Please read and respect our local Wiki and mapping conventions and leave as we tagged it ... tertiary. I have changed it back as I have done for much of Kaarts other work in the CM area.

Kaart logic defies me ...

way/203225104 - two sides the same road separated by a grass median. Its access to the University and therefore a service road. You change one side to unclassified and leave the other as service.

way/449472769 - its a layby used for Red taxis to pick up Government employees. On the South side of Hwy 11, you decide it should be a trunk_link, while the identical layby on the North remains as unclassified.

Why do you change roads just for the sake of change - your consistency leaves a lot to be desired ? I'll fix it just as I do all your other blunders.

I see u fixed it ... thanks.

Fixed.

Way: บ้านแม่ย่อย-สันศรี ซอย 2 (700312239) has been added as just a line, with a name.
Is there a Soi here as its hard to tell with the tree cover ?
If so, please tag the way correctly. Or delete if not.

Thats the Changmoi Tudmai Road (way/203681410) to clarify, but is one of many.

Why has this been changed to a residential road ?
This road does not function as access to housing but serves to move traffic through the city. Please read the OSM Wiki on Highway classifications before changing things just for the hell of it.
Along with a lot of your other bad edits, we are slowly fixing them. Please go and play elsewhere.
Russ.

Way History: Sridonchai Road (20409525) - The Kaart logic defies me here ....
You have changed this road to Tertiary ... OK, you could argue its one of the main roads exiting the moat, but then the one-way Charoenprhatet road, that all the same traffic flows into, has been left as unclassified.
But then you also chose to make the Chaing Klang road tertiary, when this is basically the Night market, full of pedestrians, and not suited for volume traffic.
Everything you do seems hit & miss, and devoid of any local knowledge.
I'm changing stuff back the way it was unless you can come up with a valid explanation for your seemingly arbitrary actions.
Russ.

I fear the Chiang Mai map has now just become a battleground for the "highway status changers" ....
This poor little way (way/136605132) was once part of the road that followed the river. Alaska Dave tagged it as unclassified many years ago and added to tag to stipulate it was not one way.

Then 6 months ago, a member of Kaart decided it needed to be a trunk_link.
A week later another Kaart member made it a secondary_link.
Another two days passed when a third Kaart member decided maybe after all it was unclassified.
That lasted a whole 2 weeks, but finally succumbed to another change by yet another Kaart member, and it became tertiary.
But it didn't stop there ... a month later, enter someone from The Grab team, who, not wanting to be outdone, decided it should be secondary ... and to crown it, added a one way tag, which the best of my knowledge, it is not (I'll check later).
Finally Grab had one last parting shot and changed it to a secondary_link, a month later.

Grab/Kaart - please take your indecisiveness elsewhere. Your efforts are becoming the laughing stock of the seasoned OSM community here.
Russ.

Perhaps you jokers in Kaart Utah can explain your rationale about the road that runs along the canal ... for 10 years this way/77848398 has been correctly tagged as an Unclassified road. Its starts at the junction with the 1096 and that's where mile-marker Zero is.
So firstly you decide to reclassify it as a residential road along its length ... good move Mr Otter, a canal on one side, fields the other bar a 7-11. But then Mr Rose comes along and decides it should go all the way up to Tertiary status - something we use here for roads that have a reference number.
But yet for some reason, he decides to just change it from the junction with the Samoeng Old road and not at the start ?? That can stay as residential, which of course, its not.
Could Kaart please explain why changing the status of roads in such a haphazard manner is "improving our map" ? Anyone coming down the 1096 from Pai, and heading for city is likely to be directed along the residential soi on the West bank, given its equal status with Kaarts newly changed road on the right.
I say again, Kaart please explain your logic, and don't fob us off with some excuse about a mistake - you are making mistakes all over Chiang Mai and its really pissing local mappers off to see our hard work being trampled over !

I have sorted the mess out now.
