It's probably easier to just shift the data for Z and A by half a unit:

	splot 'data' u ($1-0.5):($2-0.5):3

With this shift and corners2colors, it should work.

	set size ratio -1

Is supposed to do that.  I'm not 100% sure it works in 'map' mode, though.

I suggest you drop the 'landscape' out of that line.

That line's broken.  There should be several semicolons in there.
