EPSG:4162 - Korean 1985

  • Republic of Korea (South Korea) - onshore. code 5134 (default)

Selected transformation

Method: Longitude rotation

Remarks: Caused by redetermination of longitude of Tokyo datum origin in 1918. Korean 1985 is based on the 1918 determination.

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: Tokyo 1892

Datum: Tokyo 1892

Ellipsoid: Bessel 1841
