Please do not remove name:ko tags!!

Hi there. You didn't really fix this. I am a local mapper and this building was already properly mapped. You extended the building outline to another building that is in front of it. It's hard to see from the aerials. Please be careful with armchair mapping.

Why did you move ABC Bakery? I moved it back. It was in the right place.

I disagree. What is the purpose of using a node for the hotel? The building is the hotel, with some other things inside it. The other things can be nodes inside the building area.

Ok. Well, I think the building should be named for the hotel, and nodes inside for the mall, and Paris Baguette and KFC.

Why did you remove the name of the building?

Hi there,

The roads I looked at in South Korea are badly misaligned. Aerial photos are often poorly aligned and must be adjusted. Please use GPS traces and realign the aerial photos before using them.

I found images on Korean street-view software, so I repositioned the end-points on the correct buildings.

Ok. The top and bottom stations and pylons are (just) visible on Bing aerial photos, but the top station has been erased on Korean aerial photos, probably because it is next to a communication tower.

Ok thanks. I might be able to go there. If I do, I'll check it out for sure.

Are you sure there is a cable car here? I can't see it on any Korean maps.

Thanks.

Hi there. Your recent edits in this area have many mistakes. Please change your edits to the previous state.

The old road is not connected. It is still present and may be re-used for local traffic. The area is still under construction. Please check with local mappers before editing.

Hi there!

This road is not connected, which is why I didn't connect it.

Please do not blindly follow some software's idea of what is an error in OSM. There is no substitute for local knowledge (I live locally). If you are not sure, move on to another area, or ask the original mapper.

Thank you.

I undeleted parts of the old highway 88. It should not be deleted. It still exists!

Hello again. This road was correctly classified, and checked with gps. Bing imagery is not accurately aligned, and you can not determine the road classification from the imagery. Please revert this edit.

Hi there. There are two problems with your edits. Firstly, Bing aerial imagery is not accurately aligned. You must move the image layer before editing, or your features will be in the wrong place.

Secondly, Bing aerial imagery is quite old in places. The motorway exit you have mapped was demolished 3 months ago and has been deleted. Please revert your edit.

Hi there,

Have you been moving the roads to match the aerial photographs? Please don't do that. The aerial photographs are not accurate.

You must use GPS tracks and aerial photographs together.

Step one: Move the aerial photograph to match the GPS tracks.
Step two: Draw the roads and other features you can see.
Step three: Adjust the position of the aerial photographs when you move to different areas of the map.

In JOSM the menu option is this:
Imagery | Imagery Offset | New Offset

I will fix highway 12 (88 Olympic Expressway). Construction is almost finished.

A lot of your edits are wrong. Please do not change things for the sake of it. Please do not rely on aerial photos- a lot of them are out of date. I have to correct your mistakes. If something I have mapped does not look right I would prefer you asked me.
