Critical problems about administrative boundary level of South Korea

GPIOIPG · 2019-05-18T12:39:52.000Z

South Korea has unique administrative unit, Dong(동) and Li(리). Li is similar to Dong. So I explain about Dong only.

There are two type of Dong, Administrative Dong(행정동) and Legal-status Dong(법정동).

Administrative Dong is used as administrative service area of Local Autonomous Entity. And Legal-status Dong is used for address system and trading land. Boundary of these two type of dong is differ each other. (more information : https://en.wikipedia.org/wiki/Dong_(administrative_division))

Problem is that these two of dong is SAME ADMINISTRATIVE LEVEL. So boundary of Dong is conflicted.

How can I solve this problem? OSM community in South Korea couldn’t get conclusion.

Don’t use boundary=administrative for both: reserve that for the actual administrative entity. For the other one use a different boundary=* tag. We have the same issue in the UK (although I think using admin_level=6 for one of those was not the best policy).

An alternative is to add a designation tag to delineate which type of legal entity it is (again we have this in the UK because we have a myriad of confusing administrative entities with different names in different part of the UK).

You should probably ask Wambacher here : https://forum.openstreetmap.org/viewtopic.php?id=65676
He’s the guy in charge of controlling borders consistency in the entire world.

¿And how those boundaries should be mapped so apps doing reverse geocoding can get the right address?

@muralito: this is a widespread & common problem where postal towns & cities do not accord with administrative ones. It certainly exists in the US and UK as well.
