(null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Parameter values taken from Katanga 1955 to RGRDC 2005 (2) (code 4067) assuming that RGRDC 2005 is equivalent to WGS 84 within the accuracy of the transformation.
Molodensky-Badekas (CF geog2D domain)
