I was not able to create the transformations by adding the parameters
"src_semi_major", "dst_semi_major", however, I was able to create the
transformation when I added in the parameters "tgt_semi_major",
"tgt_semi_minor".
It is possible that "src_semi_major" and "src_semi_minor" are required
as well. But if it works without them it is worth to try.
Could you take a look at the attached file and let me know if the
modifications I have made to the WKTs are correct?
It seems close. But in the following parameters:
PARAMETER["tgt_semi_major",6378137.0],
PARAMETER["tgt_semi_minor",298.257223563]
the 298.257… value is the inverse flattening factor. Value for
semi-minor axis should rather be 6356752.314245179 (computed from
semi-major and inverse flattening factor).
