<font face="Arial">Hi Manie,</font><br>
<font face="Arial">Thanks for the idea.<br>
</font><br>
<font face="Arial">The current system in use is QND95 - the one you
are suggesting (I see) is from 1976, and its origin is "too
close".</font><br>
<font face="Arial">(Yes, I still tried it)<br>
</font><br>
<font face="Arial">Looking at the numeric values of the coords, I am
expecting something with an origin some 500Km West of Doha, and on
the Equator.</font><font face="Arial"><br>
</font><br>
<font face="Arial">And then of course I also need to consider the
possibility that the coords in the shapefile are non-sensical, so
