Selected transformation

Name: NAD83(CSRS) to WGS 84 (2)

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84 can be considered the same within the accuracy of the transformation.

Information source: "Realization and Unification of NAD83 in Canada and the U.S. via the ITRF" by Cramer et al, IAG Proceedings, Section II, Munich, October 5-9, 1998; revised 11 March 1999.
