Yes, and, for maps, I like the term "linear", because of its one-word brevity, and because it directly refers to such maps' big advantage.

For that statement about "linear projection" meaning "pseudocylindrical projection with equally-spaced parallels", to be true, then "pseudocylindrical projections" must include "cylindrical projections". But "pseudo-" means "similar to, but not...". So, if cylindrical projections are considered a subset of pseudocylindrical projections, then surely pseudocylindrical projections need another name. Isn't naming and proposing terminology one of the purposes of your organization?

Yes, and I never meant to imply that my list of "some linear projections" covered all of them. Surely it goes without saying that an infinite number of linear projections could be defined.

As for the mathematical information in your letter, my computer won't display it. The screen just shows spurious characters. To make it worse, the misrepresentation of the characters doesn't even seem to be consistent.

Could the mathematics that you posted by written in ordinary plain text characters?

Surely you aren't just saying that Y varies linearly with latitude and X varies linearly with longitude, because that was my definition. If your posting tells of something interesting or curious about linear projections that I didn't know, then I regrettably miss out on being able to display the information on this computer.
