Yes, I agree. It's still a genuine Mercator. It's just that while the Web Mercator's formulas are for the spherical form of the Mercator, geographical coordinates are required to be in the WGS 84 ellipsoidal datum, which makes it only very slightly not conformal. Which is very hard to notice.

Recently, I added the BSAM projection to my page about the Gall Stereographic projection. I noted that its reduced stretch was less objectionable. It led me to thinking that another way to have less stretch but still have 40 degrees as the standard parallel, would be to start with a projection clos...

Yes, Frye is also associated with a design along these lines.

Yes, and I do like this projection. I think it's one of many ingenious solutions to reducing the distortion. It's also a beautiful map IMO.

Yes, C.B. Fawcett did present that projection. I think John Snyder even mentions it in his "Flattening the Earth".

África only looks small compared to the distorted Northern Hemisphere, because it is exaggerated(say, Alaska, Greenland, Russia, the Arctic Archipelago of Canada.. Canada itself... Great Britain...). And also because the Northern Hemisphere has more landmasses than the Southern.

They should just adopt the Mollweide or Bromley's rescaling of it. Or even Hammer-Aitoff. Or maybe stay out of legislating such things at all. I’m not so opposed to prohibiting Mercator for world maps in a classroom setting, other than for comparative purposes, but requiring this or that projection...

Looks great! Absolutely beautiful!

I don’t know of any others, although Snyder’s GS50 is nearly such. Over the area it's optimized for, or when pathologically extended to the whole globe? It falls apart quickly outside its region of optimality; you don’t have to expand the range literally to the whole globe to see gargantuan inflati...
