Bogota 1975 / Colombia West zone

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Parameter values taken from Bogota 1975 to MAGNA-SIRGAS (4) (tfm code 15720). Approximation assumes that MAGNA-SIRGAS is equivalent to WGS 84. Accuracy about 1 part in 10^5 of distance between points, depending on relative tectonic motion.
