REDGEOMIN

Attributes

Unit: metre

Geodetic CRS: REDGEOMIN

Datum: Red Geodesica Para Mineria en Chile

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: "Guía Técnica para uso de SIRGAS y GNSS en la minería de Chile: REDGEOMIN y épocas de referencia", Centro de Procesamiento y Análisis Geodésico, University of Santiago, July 2025.

Revision date: 2026-04-21

Scope: Geodesy, onshore minerals management.

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: 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.
