Transformare WGS 84 Stereo 70

Alexandru Muresan
As dori sa va intreb in legatura cu datumul necesar in transformarea
WGS84 - Stereo70, pentru ca altitudinile afisate de GPS sa coincida cu
cele de pe hartile topo 1:25000. Daca utilizez datumul Dealul Piscului
70, altitudinile nu sunt corecte. Trebuie sa utilizez datumul Pulkovo
42? Mai concret, care sunt parametrii corecti de transformare
geocentrica WGS84-Stereo70?
Pentru transformarea geocentrica WGS84-Dealul Piscului 70
am gasit:dx 28, dy -121, dz -77;
Pentru transformarea WGS84-Pulkovo 42 am gasit mai multe variante,
unele identice cu transformarea  de mai sus.
Ma puteti ajuta sa ies din ceata?
Multumesc anticipat!
