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.
