The West Belt of the 2010 series

EPSG:5185 is KGD2002 / West Belt 2010, a Transverse Mercator projection in metres on the GRS80 ellipsoid. Its central meridian is 125° E, the latitude of origin is 38° N, the scale factor is 1, the false easting is 200,000 m and the false northing is 600,000 m. The bundled definition covers 124.53° to 126° E and 33.99° to 38.04° N, the westernmost of the four 2010 belts.

For example, the point at 125.5° E, 37.7° N is about x = 244,095 m and y = 566,820 m.

Four belts with the same false values

EPSG:5185, EPSG:5186, EPSG:5187 and EPSG:5188 share the latitude of origin, the scale factor and the false easting and northing. Only the central meridian changes, by 2° from one belt to the next. Because the numbers look alike, data assigned to a neighbouring belt lands roughly 180 km east or west of where it belongs.

How mapverter handles EPSG:5185

  • A .prj is matched by its EPSG code or by its projection parameters.
  • Without a .prj, mapverter shows up to six candidates, and EPSG:5185 is among them in both interfaces when the data fits the West Belt. At 125.5° E, 37.7° N, for example, the Korean interface lists EPSG:5186, 5174, 5181, 5185, 5187 and 5188, and the English one EPSG:3857, 5186, 5181, 5174, 5185 and 5187. Check on the map that the data lands in place.
  • This page presets EPSG:5185 as the target for SHP and CSV output. KML, KMZ, GeoJSON and GPX always use WGS 84.

Frequently asked questions

How can I tell whether my data is in EPSG:5185 or EPSG:5186?
The numbers alone can look the same. Check the .prj or the data documentation, or preview EPSG:5185 and EPSG:5186 on the map in mapverter, searching by code if one is not listed, and keep the one that puts the data in the right place.
Can I convert West Belt data to the Central Belt?
Yes. Open the EPSG:5186 page, which presets that target, then add the file with its .prj and download SHP or CSV.
Are EPSG:5185 coordinates in metres?
Yes. The x and y values are metres from a false origin 200,000 m west and 600,000 m south of the point where 125° E meets 38° N.
