Erosion simulation of a full globe

Adams World In A Square 2 is very much unlike what I described, as it requires complex math and has curved parallels at varying distances from the equator (it's also conformal, which is a nice property that makes for pretty maps). What I described is a simple linear transform with absolutely hideous properties from a cartographic perspective. You wouldn't want a map in that projection for any purpose than computer-based usage: humans have reacted badly to the projection that I described.

Oh, I see what you mean. Just squashing it into a square and turning the raster onto one corner? Yes, you wouldn't display that I suppose, but there seem to be plenty out there that look horrid. I guess that if the data points are always more or less equidistant it will support the calculations though.

Sorry I was confused. I've edited above.

Creating a map projection (or anything, really) is difficult because you're always optimizing for some desired set of properties. Equal-area, conformal, equidistant, political agenda, ease of use for navigation, simplicity of computation, novelty, and aesthetics are some of the more common dimensions. The projection that I described is optimized purely for ease of use with digital computers and minimizing memory use while being semi-quick to compute the forward or inverse projection using simple linear transforms. It has terrible aesthetics, which is why I described it rather than showed a map in it. It's similar to one of the aspects of the Collignon projection, but isn't equal-area.
