(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 TM75 to ETRS89 (1) (code 1041) assuming that ETRS89 is coincident with WGS 84 within the accuracy of the transformation. Use iteration for reverse transformation WGS 84 to TM75. May be emulated by NTv2 alternative code 6947.
