EPSG:6666

JGD2024

Attributes

Unit: metre

Geodetic CRS: JGD2024

Datum: Japanese Geodetic Datum 2024

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Geodetic Department, Geospatial Information Authority of Japan (GSI).

Revision date: 2026-04-21

Scope: Geodesy.

Remarks: Replaces JGD2000 (CRS code 4946) with effect from 21st October 2011. On adoption of JGD2024 (vertical) with effect from 1st April 2025, the name of this geodetic CRS was changed from JGD2011 to JGD2024; there is no change of definition or of coordinate values.

Area of use: Japan - onshore and offshore.

Coordinate system: Cartesian 3D CS (geocentric). Axes: geocentric X Y Z. Orientations: X and Y in equatorial plane, X positive through intersection with prime meridian, Y through 0°N 90°E. Z axis parallel to mean earth rotation axis and positive towards North Pole. UoM: m.
