EPSG:9696

REDGEOMIN

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: REDGEOMIN

Datum: Red Geodesica Para Mineria en Chile

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

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

Revision date: 2026-04-21

Scope: Horizontal component of 3D system.

Remarks: REDGEOMIN coordinates are updated on a biannual basis identified using syntax "REDGEOMIN([frame]@[epoch]", e.g. REDGEOMIN(IGS20@2024.0), REDGEOMIN(IGS20@2024.5), etc. This EPSG record references any of these updates without distinction. Users should include the update used in the metadata of their spatial data metadata. Data should be reduced to this epoch using the ADELA deformation model.

Area of use: Chile - onshore and offshore. Includes Easter Island, Juan Fernandez Islands, San Felix, and Sala y Gomez.

Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
