CRS Search Coverage
Search CRS definitions, areas of use, and proj4 strings by EPSG code or coordinate-system name. Coverage includes the Korean 1985 family EPSG:5173–5178 and KGD2002 family EPSG:5179–5188.
Send a selected CRS to the Coordinate Converter. Details also show whether a code is current, deprecated, or replaced.
Frequently asked questions
What if the CRS I find is marked withdrawn?
A withdrawn code like EPSG:5181 shows its replacement in the detail view. Use the replacement for new data, but keep the original code when interpreting existing datasets that declare it.
How complete is the Korean CRS coverage?
It includes both the legacy Bessel 1841 family (5173–5178) and the GRS80/Korea 2000 family (5179–5188), each definition sourced directly from the EPSG registry.
