Description
In netcdfdataset.cpp, line 1993/1994, I believe that the inverse flattening calculation is wrong:
dfInverseFlattening =
1.0 / ( dfSemiMajorAxis - dfSemiMinorAxis ) / dfSemiMajorAxis;
should be:
dfInverseFlattening =
1.0 / (( dfSemiMajorAxis - dfSemiMinorAxis ) / dfSemiMajorAxis);
The first formula yields values below 1.0, the second (corrected) formula yields values around 300 for WGS 84.
