The East Belt of the 2010 series

EPSG:5187 is KGD2002 / East Belt 2010, a Transverse Mercator projection in metres on the GRS80 ellipsoid. Its central meridian is 129° 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 128° to 129.65° E and 34.49° to 38.64° N.

On the central meridian x is exactly 200,000 m: the point at 129° E, 35.2° N, for example, is x = 200,000 m and y = 289,283 m.

Do not confuse it with the Central Belt

EPSG:5186 uses the same latitude of origin and false values, but its central meridian is 127° E. Data in EPSG:5187 that is read as EPSG:5186 lands about 180 km west of its true position, and the reverse mistake moves it east. EPSG:5185 and EPSG:5188 complete the set of 2010 belts.

How mapverter handles EPSG:5187

  • A .prj is matched by its EPSG code or by its projection parameters.
  • Without a .prj, East Belt numbers also fit the other belts and the Korean 1985 systems, so mapverter shows up to six candidates, and EPSG:5187 is among them. Data at 129° E, 37.5° N, for example, gets EPSG:5186, 5174, 5181, 5185, 5187 and 5188 in the Korean interface and EPSG:3857, 5186, 5181, 5174, 5185 and 5187 in the English one. Preview EPSG:5187 on the map before you confirm.
  • This page presets EPSG:5187 as the target for SHP and CSV output. KML, KMZ, GeoJSON and GPX always use WGS 84.

Frequently asked questions

My data appears about 180 km away from where it should be. Why?
The 2010 belts share the same false easting and northing, so a file assigned to a neighbouring belt moves by 2° of longitude. Check whether the data belongs to EPSG:5187 or a neighbouring belt and assign the correct one.
Can I convert EPSG:5187 data to EPSG:5186 or EPSG:5179?
Yes. Open the EPSG:5186 or EPSG:5179 page, which presets that target, add the file with its .prj and download SHP or CSV.
Can I keep EPSG:5187 in KML?
No. KML is always WGS 84 longitude and latitude. Choose SHP or CSV to keep EPSG:5187 coordinates.
