Today's prompt was 'moth'.

Back to drawing the world map as quads, with the polar quads as extreme quads which are actually a triangle fan. Since that polar row is a triangle fan, there must be three of them and in fact the sides of each quad are curved and each row of quads is either a curved strip or a polar circle; we can go into the geometry of a sphere including great circles and lunes or whatever they're called but I'm just trying to fake up some world surface maps and failing miserably! 8-P

We're building the world map down and out from the north pole. Each row is made up of a number of quads side by side and each quad is either above or below sea level, is land or sea. Furthermore, each quad has a central longitude and is a thousand kilometers tall or high, a thousand klicks from north to south so that can average top and bottom quad length and get the (approximate) area. Each quad is actually a 'hex' with three top points, leftmost, middle and rightmost, and three bottom points, leftmost, middle and rightmost.
