PROJECTION and DATUM
'All Russian topographic maps currently use the Gauss-Krasovskii (GK or
sometimes Gauss-Kruger) grid projection
system based on Pulkovo 1942 datum Krasovskii spheroid. Conversion to Western
map projections can easily be
accomplished. '
If this information above is correct then the following choices below from the
mapinfow.prj file snippet ought to work.
The URL at bottom of message has even more current information for a Pulkovo
1995 datum.

Subject: MI Siberian Projection
I am looking for any information on the projection,datum and ellipsoid of
Russian 100,000 and 50,000 topo maps and if anyone has successfully used
this projection in MapInfo. I believe the ellipsoid is Krassovsky. The area
of interest is eastern Siberia.
Any assistance is appreciated.
Regards
George M Smith
