Double Sided Square To Octasphere!

Back to the rectangle, or double-sided square to octa-sphere. For now, I'm just going with a rectangular grid. You can imagine two squares back to back, which you can blow up into the octa- sphere which I can't seem to shut up about... This is basically two hemispheres side by side; see the 'octasphere' for what it's going to look like. Probably the north and south hemispheres, but you can think of them as the east and west with the poles at the top and bottom of the map. Arable land is land quads bordering sea quads, so, yeah, needs work! 8-P

Target- 82.78%, 22 blobs, 77 sea. 3.14% sea and 6.36% arable

Planet Mass- 0.73 Earths, Gravity- 0.95, Circumference- 35091.2 m. km^2 and there are 70 quads across, each 7.4 pixels wide. The surface area is 391.9 m. km^2, and each of the 2450 quads is about 0.159 m. km^2
