JGD2024

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: JGD2024

Datum: Japanese Geodetic Datum 2024

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: EPSG. See 3D CRS for original information source.

Revision date: 2026-04-21

Scope: Horizontal component of 3D system.

Remarks: Replaces JGD2000 (CRS code 4612) 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: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
