[carl voyer]

Thank you to you for asking ESRI.
I'm still looking but still can not find. I do not despair of finding this development.
soon

Any updates on this? Have you gained any information in the past year? Is there anything one might do to help you?

Perhaps the Cahill octahedral would be an interesting alternate?

Or perhaps any of the other platonic solids...

I've been researching this and I had a chat with a friend who is an intellectual property lawyer.
Providing the ability to map to an icosahedron should not be a problem as long as you don't call it a dymaxion projection, and ensure that the default mapping is NOT the protected projection.

Others have mapped to a 20-sided solid before and since; it's the particular projection, not the projection medium, that can be protected.

Thanks for trying to be helpful. The inquiry is specifically about Bertin’s projections. Nobody’s looking for “alternatives”. If you have information about Bertin’s projections, feel free to chime in.
