Korean 1985 / East Belt

Republic of Korea (South Korea) - onshore. , accuracy 1.0 m, code 5191 (default) [7]

Selected transformation

Method: Molodensky-Badekas (CF geog2D domain)

Remarks: Parameter values from Korean 1985 to KGD2002 (1) (code 5189). Assumes KGD2002 and WGS 84 can be considered the same to within the accuracy of the transformation.

Information source: OGP

Revision date: 2023-07-17

Attributes

Unit: metre

Geodetic CRS: Korean 1985

Datum: Korean Datum 1985

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: National Geographic Information Institute (NGII).

Revision date: 2010-06-30

Scope: Engineering survey, topographic mapping.

Remarks: Replaces Tokyo 1892 / Korea East Belt (CRS code 5171). Although it was intended that the grids were for most practical purposes coincident, a 10.405" (250m) longitude offset was introduced. Replaced by Korean 1985 / Modified East Belt (CRS code 5176).

Area of use: Republic of Korea (South Korea) - onshore between 128°E and 130°E.

Coordinate system: Cartesian 2D CS. Axes: northing, easting (X,Y). Orientations: north, east. UoM: m.
