I don't have any source other than direct usage experience. Regarding the reasoning behind the change you can refer the urban roads section of this wiki osm.wiki/India/Tags/Highway

It says trunk highways are "These corridors usually carry the bulk of freight traffic from one end to the other, like ring roads, or roads connecting the ports."
These roads are neither ring roads or connect to ports.

It says Primary highways are "Roads that carry huge volumes of traffic between arterials, or between the city center and its highways. Can be used to differentiate between arterials that have sufficient grade separation, vs. those that do not."

The roads I changed to primary don't have any form of grade separation and mostly people walk on the road edges along with vehicles. So urban arterial road without grade separation is Primary and urban arterial road with grade separation and a ring road can be Trunk

Hi
This is an arterial road and was never closed for metro work. Won't you even spare a minute to verify before you make a change. This kind of vandalism is very wrong and unacceptable. Seeing a lot of this kind of maniacal edits from Swiggy.

Hi syedk,
Then there must an error in your process. Otherwise perfectly alright roads won't be tagged as under construction in multiple places by your team. Today alone I fixed 3 similar issues created by your team.

Hi syedk. I am regular user of this road and this is a decades old road. Why are you changing a functioning road to Under Construction tag. Swiggy guys are repeatedly doing this and using terms like evidences and ground truth. Either your satellite imagery must be extremely outdated or the GPS traces of your employees must be extremely outdated. Please check the veracity of data before taking it as Ground Truth or Evidences.

Hi madba008. I am regular user of this road and the construction is completed long back. Why are you changing a functioning road to Under Construction tag. Swiggy guys are repeatedly doing this and using terms like evidences and ground truth. ither your satellige imagery must be extremely outdated or the GPS traces of your employees must be extremely outdated. Please check the veracity of data before thinking it as Ground Truth or Evidences.

If you are making edits based on GPS traces of your drivers, then do the basic thing of checking the date of the GPS record. This one-way stretch has been modified many months ago. And please don't put GROUND TRUTH in your edits, it's a joke.

ஆறுடைய அனைத்து பகுதிகளும் ஒரு பகுதியாக இருக்க அவசியம் இல்லை. அதற்கு தான் Relation உள்ளது. புதிதாக வரையப்படும் ஆறுகளை ஒரு பகுதியாக வரையலாம். ஏற்கனவே பல பகுதிகளாக வரையப்பட்டு Relation இல் இருக்கும் ஆறுகளை ஒரு பகுதியாக மாற்றுவது தேவையற்றது.

Hi Navk,

While there is no way now a river basin can be tagged as a natural basin, deleting the entire relation is not the right thing to do. You could've deleted the natural:water and water:basin tags. Deleting entire relation is loss of valuable information.

It can just be a multi-polygon relation as before.
Refer other examples,
Krishna Basin relation/11547113#map=5/16.447/76.113

Kaveri Basin relation/11201998

Kindly refer them and restore the information that you've done away with.

Hi,

This is clearly an internal road within an institution. Why are repeatedly changing the highway type to Motorway. Please refer OSM wiki pages to know about highway classification. You can't change public data wrongfully for your project needs.

Hi,

Why have you made the roads in this entire area as bridges? Kindly can you change this edit. This is not correct, and made without local knowledge.

Thanks,
Ti_Ru

Hi Mk26,

Welcome to OSM community. There is an issue with your recent edit.

ECR is not a motorway. You can go through this wiki as a reference for road classification.
highway=*

Hi Caesar N,

You have changed the classification of NH44 section from Kalligudi to Virudhunagar into Motorway from Trunk Road. A motorway is an access controlled road with specified entry and exit points. But this stretch doesn't have any such features. Trunk classification would be ideal.

highway=motorway

Can you change them back to Trunk classification

Happy Mapping,
Ti_Ru

Well I ain't getting any money for this and doing this in my free time. Unfortunately am not able to complete the canals. But I have marked them while doing a road edit, so that similar minded guys like you can complete it. If you got the time for it, just follow the satellite imagery and complete the canals, they would either join a river or end in a reservoir/lake. Thanks for your concern and happy mapping.

Hi. It was a trace done over dig marks in satellite imagery and had used a few news articles for determining the purpose of the pipelines. Thanks.

Why have you changed Traffic flow tags in Kalavasal Junction. Do you have any new local knowledge? If you do not have local knowledge, kindly don't mess with the traffic flow details. You had done similar changes in Goripalayam too, left a comment there. Please don't!

Why have you removed one way traffic tags in Madurai Roads, esp. Race Course Road and Goripalayam area? You have any new local knowledge?

Thanks for your kind words of appreciation. : D

Yes there is a big reason.

I don't understand this convention. In North African countries Arabic and Tamazight scripts are used. In West Asia, Arabic, Persian and Urdu Scripts are used. In Ethiopia and Eritrea, Ge'ez script is used. In former Soviet countries in Eastern Europe and Central Asia and Russia, Cyrillic script is used. In Greece, Greek script is used. In Nepal, Devanagari script is used. In Bangladesh, Bengali script is used. In Myanmar, Burmese script is used. In Thailand, Thai script is used. In Cambodia, Khmer script is used. In Mongolia, Mongol and Cyrillic is used. In China and Taiwan, Chinese characters is used. In both Koreas, Hangul is used. In Japanese, Kanji is used. In Maldives, Dhivehi is used. In Sri Lanka, both Tamil and Sinhala are used.

So why not in India? When the whole world is following a different convention by taking pride in their scripts , why are Indian OSMappers saying no Romanized script is better.

Just why????

Hi, thanks for your suggestions.
1. I was unaware about the conventions in the mapping of populated areas as places. Just now got familiar of it and I'll make amends in further edits. Regarding this particular changeset your suggestions are correct. But the problem is I'm familiar only with ID and not JOSM. So, can you please revert the changeset.
2. At the time of merging the river segments, I didn't get the concept of relations clearly. I'll make amends in further edits. But I think reverting this change will be pretty difficult as it was done over multiple changesets and reverting those will also modify the other changes in those changesets.
