<DIV><FONT face=Arial size=2>Hi all</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm not a very expert in datums shift and
projections so, eventually, I'm sorry for my basic question.
</FONT></DIV>
<DIV><FONT face=Arial size=2>I have a map where are drawed the grids in two
different datums Gauss Boaga (Rome 40 datum) and UTM (eur50 datum). I'm not sure
that parameters (dx dy dz) for the datum shift indicated in the internal datum
tables or epsg or NIMA tables are very good for my little area of
work so I would like know if is it possible desume (and in which way)
my user defined dx dy dz for the molodensky datum shift R40 --> ED50
directly from the two grids drawed onto map or if I need of other
parameters?</FONT></DIV>
<DIV><FONT face=Arial size=2>Many thanks in advance.</FONT></DIV>
<DIV><FONT face=Arial size=2>Giorgio. </FONT></DIV></BODY></HTML>
