<div><div>At the time, Korea was pretty sparse in terms of road coverage and POIs. But there was a problem when the import was done. Roads were duplicated and overlaid, and, obviously, didn't join up with existing roads. Often, chunks of road from the new data were missing too, so it didn't all join up with itself.<br></div>
<div><br></div>
<div>The NTIC data was not quite up-to-date either. For the last decade or so Korea has been building roads at an astonishing pace. New major roads have been constructed. Existing roads have been upgraded, and even minor roads have been realigned or generally improved. So the NTIC data was useful, but old, and still a lot of work was required to map Korea.<br></div>
<div><br></div>
<div>It's quite possible that some roads tagged 'NTIC' have just been extended from that import, and the tag has been retained.<br></div>

<div>On this page of the NTIC website there is a small legal section. <a href="https://intl.its.go.kr/en/01_01">https://intl.its.go.kr/en/01_01</a><br></div>
<div><br></div>
<div><div>National Transport System Efficiency ActArticle 89 (Encouragement of Private Participation and Advancement into Overseas Markets)<br></div>
<div>④ The Minister of Land, Infrastructure and Transport may designate and run an agency dedicated to support work under Article 89.3 above according to the Presidential Decree <b>to support international cooperation and overseas market entry of industry related to intelligent transport systems.</b><br></div>
</div>
<div><b></b><br></div>
<div>I am not legal expert but to me this implies that it can be used by international organisations. However, it doesn't say anything about the procedure or how it can be used. I suggest contacting the NTIC about this.<br></div>
<div>But as Martijn said earlier, you have to be sure the source is actually the National Transport Information Center. Therefore, first contacting the users who used that source would be best.<br></div>

<div>Apparently there is an API there for use. But being "national" I suspect the law against transferring Korean geospatial data to places outside Korean control is still the governing factor.<br></div>
<div>You can use the API to look at the data, but I would expect they would frown on the practice of tracing the data into the OSM database.<br></div>

<div>Are you positive this "National Transport Information Center" is the source referred to here?<br></div>
<div>Since there are already more than 40,000 ways (I didn't count nodes) with source=NTIC, I guess people have already done so at some scale. Is there any way to trace back who / what group did this and what permissions, if any, they sought? <br></div>
<div>The best I can do is list the top 5 users who most recently edited ways with source=NTIC:<br></div>
