EPSG:15720

Bogota 1975 to MAGNA-SIRGAS (4)

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

Revision date: 2007-07-02

Scope: Transformation of coordinates at accuracy of about 1 part in 10^5 of distance between points, depending on relative tectonic motion.

Remarks: May be taken as transformation to WGS 84 - see tfm code 15721. See Bogota 1975 to MAGNA-SIRGAS (10), tfm code 15733, for an equivalent transformation using the Molodenski-Badekas 10-parameter method. OGP recommends this alternative.

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Colombia - region IV - between 5°N and 9°24'N and between 74°24'W and 72°W.
