Bogota 1975 to MAGNA-SIRGAS (9)

Attributes

Geodetic CRS: Bogota 1975

Datum: Bogota 1975

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: EPSG

Information source: Instituto Geografico Agustin Codazzi (IGAC) publication "Aspectos prácticos de la adopción del Marco Geocéntrico Nacional de Referencia MAGNA-SIRGAS como datum oficial de Colombia". http://www.igac.gov.co/MAGNAWEB/DocumentosMAGNA.htm
