Bjørn,

First, it does not appear the problem is related to GDAL or C# since
people get the same results with cs2cs which is a much more direct
connection to the proj libraries.  So I think you can focus here on
why you get the wrong results from cs2cs.

You have posted the issue here, and clearly at least a couple people
have looked at it quickly with no obvious solution.

I can see two further steps:

  o You can dig up papers on the coordinate system in question and try to
    understand the parameters better and see if you can come up with a
    better PROJ.4 string to represent the parameters.  Possibly this would
    invole comparing how this projections works in other systems.

  o You could attempt to commercially engage someone to help you with the
    problem.  Possibly you could interest Gerald in the issue with some
    inducement.  I might be willing to take a crack at it on a
    no-risk-if-I-fail basis.

Best regards,
