Thu Apr 01, 2021 14 Projections for 2021 (Part 4)
If you wonder what this is about at all, you probably didn’t read the intro.

| Remarks | A Wanger IX variant, derived by Umbeziffern from the equatorial azimuthal equidistant projection, minimized distortion by application of the Airy-Kavrayskiy criterion. For more information, refer to my blogpost The Frančula Projections or Frančula’s original paper Die vorteilhaftesten Abbildungen in der Atlaskartographie (German). |
This months’ projection is the Frančula XIII.
I introduced it recently in a blogpost (see link in the table above)
and all that I can add is: Meanwhile I know that it has favourable
distortion characteristics not only by the Airy-Kavrayskiy criterion,
but also by Goldberg & Gott’s metric.
And that I still think it’s a great projection for world maps
that don’t need a property like equivalence or conformality.
’nuff said.
Next month, we’ll have … well, let’s say a cousin of the Frančula XIII.
