Attributes

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Instituto Geografico Agustin Codazzi (IGAC) resolution 715/2018 and SIRGAS2017 symposium presentation "Implementación de la Actualización del Marco Geocéntrico de Referencia MAGNA-SIRGAS" by Diego Cortés et al.

Revision date: 2023-02-02

Scope: Geodesy.

Remarks: Active network referenced to ITRF2008@2011.76 and passive network referenced to ITRF94@1995.4 updated to ITRF2014 using IERS transformations EPSG:7790 and EPSG:8075 respectively then VEMOS2009 velocity model applied to bring coordinates to epoch 2018.0.

Area of use: Colombia - onshore and offshore. Includes San Andres y Providencia, Malpelo Islands, Roncador Bank, Serrana Bank and Serranilla Bank.
