Re: the commented-out 7-parameter transform
I originally put this in and the source is now at
http://www.asprs.org/resources/grids/08-2001-swiss.pdf
As far as I can remember the two reasons I left it commented were:
1) The parameters given are for CH1903+ which is apparently different from
CH1903 - I have no idea how much or if the differences are big enough to
be relevant.
2) I didn't have any test points to verify the parameters - in particular
we always need to check the sign of the 3 rotation parameters (the 4th,
5th and 6th numbers out of the 7) as the American/European conventions are
different.
If somebody can verify these two points then we can uncomment the
parameters.
