Geodetic CRS: Korean 1985
Datum: Korean Datum 1985
Ellipsoid: Bessel 1841
Prime meridian: Greenwich
Data source: EPSG
Information source: OGP
Revision date: 2023-07-17
Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
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.
Method: Molodensky-Badekas (CF geog2D domain)
Area of use: Republic of Korea (South Korea) - onshore.
