In English there are spaces between words. Use Thai script in "name" and English/RTGS in "name:en"

Hello and welcome to OSM.
Thank you for your contributions around ซอย 3 หมู่ 9 ตำบล นครปฐม. Please double-check the tags you choose. Here you selected highway=tertiary for residential roads. This will lead to problems when the map is rendered. Also make certain that crossing ways are having a node at the crossing point. Without this a routing engine can not understand that it is possible to get from one way to the other. So it would not allow you to turn there. I fixed the issues for you already. You still might to go back to the area to add street names. Use the "name" for names in Thai script. "name:en" for English/RTGS.

Please do not use abbreviations for names. It is impossible for an algorithm to expand these in all conditions while it is simple to shorten them by software. So write "Road" instead of "Rd."

Please also avoid using the tag highway=unclassified. This does not mean that you don't know the classification. It is actually a way to mark roads which for example connect villages to the main highway network but have not yet received a classification (from DRR, like the 4 digit numbers)

As mentioned in another comment, please make sure to use correct tags. Otherwise data consumers can't make sense of your contributions. Worst case it won't be considered at all. I fixed residential roads tagged as highway=road instead of highway=residential. Also parking isles also have their own tagging.

Welcome to OSM.
The way you added is a typical residential way. So please tag it as highway=residential. It is important that we use the correct tags in OSM as the data will be used for many purposes extending the simple display of a map. osm.org/way/559992740

Please feel free to check out the forum in case you have questions regarding how to best tag things in OSM.

way 555897421:
is tagged as footway. But has additional tags to allow cars/motorbikes. Could it be simply a very narrow road? Maybe highway=service together with service=alley. Or is it a one-lane residential just wide enough people can get their car in&out? would be lanes=1. There is a note mentioning a free public parking. Is this still there? Would then be worth tagging and marking the note as resolved. Note 810618

what are you doing? First you deleted hundreds of way, and now adding them from scratch?

A nice first edit. Check out the different imagery layers you can use. You will notice that some offer details others don't. Also take note that sometimes the roads look shifted on different layers. Best is to compare the imagery position with GPS traces available and choose the best fitting one. Just as a hint: don't re-align existing roads unless you are absolutely certain about the better alignment. (don't worry, you didn't do).

With your mapping I have a question: You added a highway=residential with an angle. There is another road continuing to the east. I added this now. Could it be, that the north-south section is a different soi? Maybe it even has a name? You could re-visit your addition and add a name to it. We tag the name in Thai script in "name". The RTGS with Latin characters would be in "name:en".

Hello,
welcome to OSM.
You added a short way leading to administrative buildings (way 556677629). The road classification in OSM is quite important. unfortunately "secondary" is the wrong type for such a way. I changed it to "service" which matches much better the function of it. I recommend to reach out to other mappers to get some support in case questions come up about how to exactly add something to OSM. You can send me a message via OSM if you need support.

what happened here? node 4990576441

a huge gap in a major highway. I have re-connected the ways based on aerial imagery to have a routable network again...

Hello and welcome to OSM Thailand.

way 555900975: Please explain what you mean with oneway=reversible. I know that sometimes entry to a road from one side gets blocked, eg during busy hours. But infrequently reversind the one-way? With this being in Bangkok nothing is impossible, but please clarify. Same for way 402310959
and way 555900974

way 555900976: In Thailand we don't have the legal concept of a living_street. It's a highway=residential. Also adding all those special sub-tags like horse, etc is not necessary and is typically only added if it differs from the norm. Same for way 555900977.

In general, please make sure that your ways are connected to each other, otherwise routing is not possible. Also keep roads with are not needed to be separated for mapping reasons connected together. Gap at node 3585868101.

It sounded like an import, so I wondered what source was used and whether it would also contain data for Thailand. Rendering of all those unnamed peaks is a bit weird, but this is a different story.

Can you document on how to get the AMS maps on the main page of Laos together with other data sources? osm.wiki/WikiProject_Laos

Where can these maps be obtained from? is this complete? Are there instructions somewhere on how to adjust projection and alignment and how to use as an imagery layer? I probably also ask directly Adrian for How-To details.
http://legacy.lib.utexas.edu/maps/ams/thailand/

For the large number of peaks, probably only document where they are from and what the source was in case others wonder about it as well.

I notice that your added POI line up very well with the few POI listed on google maps. Might be coincidence. But please be aware, that it is NOT allowed to copy details from google maps to OSM. We want to have the features verified on the ground. This is what makes OSM better than google. The features are actually verified (location and existence) and not automatically placed by some algorithm.

For Wat Ban Chot I added religion=buddhist, as this helps to later render the right symbol on the map.

node 5346112262
a health center is also no place of worship. Please take extra care to select the right tagging, as this is the way in OSM data is described.

way 553888009
Residential roads (the roads in areas where people typically live) are tagged as highway=residential

node 5346112258:
This was placed at the exact same location than the mistagged school above. Please check the location, as imagery does not show any building there or nearby looking like a health center

for node 5346112257:
a mini mart is most likely a shop=convenience, not supermarket

For node 5346112259:
I don't want to discourage teachers around, but โรงเรียนบ้านโนนเพชร is *not* a place of worthip. amenity=school is much more appropriate for schools.
