(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 Timbalai 1948 to GDBD2009 (1) (code 5878) assuming that GDBD2009 is equivalent to WGS 84 within the accuracy of the transformation.
Coordinate Frame rotation (geog2D domain)
