I've been meaing to get back to quads by latitude and chunks... Here I have a pretty standard oval, mostly because I have been on a word wrap to world div kick. In any case, I want to chunk up my world oval by bands of latitude and then subdivide those lattitude quads. I start with a circumference for world size, width and height.
45483 km across, 455px by 228px with a total surface area of 658.48 m. km^2
Top: 56, Bottom: 145, Left: 111 and Right: 163. Area of the quad: 46.28 m.km^2
2871 km south 0.3966102723415912 radians, 17569 km wide at that latitude
v0: 28, h0: 87, h1: 30
v2: 72, h2: 62, h3: 39
