Hello

I am almost 100% sure that the problem is wrong central
meridian, since the resulting picture shows increasing
error to the north and south. Goode projection does just
that if the central meridian (lon_0) is wrong.

The data is on Americas and that uses usually lon_0=-90.
If the inverse uses lon_0=0, the distortion is evident.

Do some experimenting with lon_0 (central meridian).
