Transformation of coordinates at accuracy of about 1 part in 10^5 of distance between points, depending on relative tectonic motion.
May be taken as transformation to WGS 84 - see tfm code 15729. See Bogota 1975 to MAGNA-SIRGAS (10), tfm code 15737, for an equivalent transformation using the Molodenski-Badekas 10-parameter method. OGP recommends this alternative.
