“To compute Ferro values to Greenwich the German
Geodetic Survey used the value Ferro-Greenwich =
17° 39′ 59.411′′” (Heinz W. Kloos – personal communication,
26 July 1982).
According to TR 8350.2, the mean solution for the
transformation from European Datum 1950 (ED50) to
WGS84 is: ΔX = –87 m ±3 m, ΔY = –98 m ±8 m, ΔZ = –121
m ±5 m. Because of the myriad coordinate systems in the
Federal Republic of Germany listed above, the error envelope
listed with the transformation parameters for WGS84 is
probably realistic. Localized transformations can offer better
accuracies when only individual networks or chains are
involved, but transformation accuracies are still dependent
on the accuracies of determination of the original positions.
Some of the positions given above were determined over 200
years ago.
