[Proj] Winkel II corrections, etc.

[Paul B. Anderson]

- Gerald,

Even though John Snyder originally thought that Winkel was refering to the
Equal-area Mollweide (1977) and later realizing that is was a Equidistant
variation (1993) that Winkel was talking about, John's formulas are still a
valid map projection. I believe that the earlier proposed 'Winkel II
(Snyder)' would be OK, or even Winkel II (Snyder's Variation). But, Map
projection naming conventions usually end up with the Originator's name
first, a hyphen, then the Modifier's name second (as in 'Winkel-Snyder
projection'). This sometimes results in confusion as to what the
Originator's projection was, but then a future version of John Snyder will
have something to write about.
Take Care,
- Paul
