Paul,

The problem here is that without any coordinate system information for
your MrSIDs you are left playing the "guess the coordinate system" game.
And I would suggest that the rest of us out here in internet land have even
less to go on than you.

If you can't get information from the original MrSID producers, then you
will basically have to mess around with a variety of guesses.  The coordinates
for your raster are enormous.  If they are in meters then 11 million meters
is roughly 1/4 of the way around the world from the projection origin.

The ratio of x to y coordinates is quite different between the vector and
raster data, so if they are near each other in the real world, it is unlikely
this is just a units issue.

I hate playing guess the coordinate system.

Best regards,
