SIRGAS-Chile 2010

Attributes

Unit: metre

Geodetic CRS: SIRGAS-Chile 2010

Datum: SIRGAS-Chile realization 2 epoch 2010

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: "Geodesia en Chile, teoría y aplicación del Sistema de Referencia Geocéntrico para las Américas (SIRGAS)", Grupo de Geodesia del Sistema Nacional de Coordinación de Información Territorial (SNIT), 2018.

Revision date: 2019-06-14

Scope: Geodesy.

Remarks: Densification of SIRGAS-CON within Chile at epoch 2010.00. Replaces SIRGAS-Chile 2002 (CRS code 5358), replaced by SIRGAS-Chile 2013 (CRS code 9146) due to significant tectonic deformation.

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.
