You have added a very nice coastline in this changeset to replace the original PGS coastline. I want to do this for a great many other islands in Alaska. However, I cannot find the exact URL to obtain these coastlines. Can you be more specific about the source URL you have provided?

Thank you

The building you added should be orthogonalized, that is, its corners made to meet at 90 deg angles. Right-click on a building outline in the iD Editor and select the "Square" setting from the flyout menu.

Okay, Carlo. Thanks for the information. I suggested JOSM because of its power but unless you want to become a regular contributor it might not be worth the time it takes to learn how to use it.

No problem about the extra work. I'm glad you want to contribute time to worthwhile projects and I'm happy you are willing to work on improving your technique.

Returning to the duplicate buildings - yep, it was probably some sort of error in the HOT task manager. Sometimes there are synchronization issues between two users working in the same area or even two versions of editing by the same user, that cause "conflicts" upon uploading. These are very difficult to resolve and most OSMers dread them. It looks like that's what happened here.

You requested a review of this work. It looks like the junction of 294 and ศก.5089 has some serious problems. One segment of 294 (way id:844947605) has 16 redundant U-turn restrictions.

The rest of the junction looks okay but if I were being asked to fix it,my first step would be to delete all of the existing U-Turn restrictions and start over.

It's hard for me to tell which of those restrictions you're responsible for but clearly it needs to be fixed.

You requested a review of this changeset. Actually my original comment belongs on a different changeset. I didn't see anything wrong with the oneway situation here so I'll give you a "pass" on that.

These buildings are okay but are not drawn very well IMO. I commented on another of your recent changesets (90482117) and made some suggestions there.

Dave

Hi again,

There are no duplicate buildings in this changeset but the accuracy of your building outlines is still pretty poor. You're using the iD Editor and it has built-in tools to make a building square, rotate it, move it, etc. After selecting the outline you right-click to open a special menu.

My advice, if you intend to become a regular mapper, is to start using JOSM as soon as possible. I don't like iD and don't see how people can use it. But that's just my opinion.

Dave

According to my Thai wife, those two names are probably the same man using two different forms of his name. Can't be sure.

I agree with you that something is wrong with a system — I have never been able to add a building over the top of another one. One way that could happen is if you are working from some sort of a "task manager" that allocates work spaces for different mappers and it didn't work as intended. A good task manager will make sure to not allocate the same area to two different mappers. Are you using a task manager?

I have a couple more questions:
What is the full name of the project you're working for? Are you getting paid for your work?

Thanks for your willingness to work together.

You requested a review of this changeset. I already removed many duplicate buildings while I was reviewing another of your changesets (#90438627) so I won't repeat my comments here.

You requested a review of this changeset. Everything you added looks good.

At your request, I reviewed this addition. It looks fine as is but because we're mapping in Thailand the English description you added really should be tagged as description:en. Assuming you are a Thai, you might consider adding a description in Thai language.

Also, according to English custom, the name Doi Tao Lake would be spelled with capital letters as I have done here. It's not a big deal as most searches would still find it but to be fully correct, that is the best way to do it.

Ive reviewed most of this changeset and the data you added/edited looks good. It's of much higher quality than your previous mapping. You're making progress. I still see buildings included in natural=wood areas, same for orchards. Maybe you could spend a little more time to outline them more thoroughly?

Sorry to be so direct but I have really never seen such poor technique. The buildings were present for a year before you added yours. It is inexplicable how you could have done what you did. And then, even if the buildings were somehow invisible to you, your "buildings" sometimes included shapes from several closely spaced but clearly _individual_ buildings. That's why I asked what were you thinking.

Using Bing imagery is not the problem. All imagery must be adjusted by downloading GPS traces and then moving the imagery until highways line up with those traces. After doing that, you can add objects with some confidence that they are positioned properly.

Whether you use Bing, ESRI or Maxar imagery, it still needs to be aligned properly and the only way to do that is by using GPS traces.

Start by reading this:
osm.wiki/Using_Imagery

There are many other places to learn about this process but that should help.

I said พิชัย บุญทัน is your colleague because he uses the exact same hashtags as you. Even if you don't know him or her personally, I consider him your colleague.

You are a new mapper and ordinarily I am very polite to new folks but we have seen so many come along lately who do weird stuff and use bad techniques that my patience has worn thin.

Thank you for asking that your work be checked. I'm sorry I couldn't be more accommodating.

This is a real mess. There are buildings placed on top of existing buildings, there are multiple buildings drawn as if they were a single building. Terrible. Why did you draw your buildings right on top of the existing ones? I see that you have done this dozens of times in this same area. What were you thinking?

All of thse of buildings were contributed by mappers who are working to help eliminate malaria. Great. But this sort of mapping will not help your cause.

I'm going through and deleting your additions but it's a big job. The Bing imagery you used is badly out of alignment so even the buildings added by your colleague (พิชัย บุญทัน) are poorly positioned. Wow, what a mess!

Please try to understand what you did and why. And please do not add any more data until you fully understand my comments.

Also, it is good practice to tell OSM how you obtained the information. Something like "source=2020-09-07 survey" or "personal_knowledge" would work. I assume that much of the info you provided looks as though it came from the restaurant's FB page. You could say that to clarify the situation.

Does the name of this restaurant appear in all capital letters on its sign or menus? If so, your work is perfect. The name in OSM should look just the way it would if you were there in person.

Hello,

You have added many wilderness_huts in this area. I think you are using that tag incorrectly. A wilderness_hut is located in wild country, usually accessible only on foot, is free and has sleeping facilities and sometimes even a fireplace or stove. Please read the description in the Wiki.

tourism=wilderness_hut

The huts you mapped are in towns. Why did you choose to map them that way? Are these places actually home stay guesthouses?

Thanks for the feedback.

I suspected that was your reason but I don't know if it's a valid one. Ideally, rendering issues shouldn't influence our tagging choices and yet, in this case, the layer tag may be appropriate. It's an interesting situation.

I'm not going to change anything or make any recommendations. I was just curious.

Dave

Hello,
I noted that you enhanced the tagging for this usually dry lake in China but I'm wondering why you tagged it with layer=-1

Can you tell me more about that tagging choice?

Cheers,
Dave
