Hydrography

Hydrography

Hydrography refers to the distribution and mapping of bodies of water. In this step, you'll determine how much of your world is covered with water.

66-90 - 80%

A tall polygon of water. Shit, I need to actually map things now.

So, I break out Photoshop, and lucky me, I still have a hexagon pattern fill. A quick googling for a unfolded dodecahedron gets me a blank template, and I fill it in. Pattern is too big, scale it back some, and shit, how do you do the area of a pentagon? 1/2*perimeter*apothem. Good thing theres a calculator. Target number is 58, fuck me this is too hard. 20% scale gets me something that looks about right:

Now we look at some chart, which tells us on the (20-sided) polyhedral map, our 80% water world should have 8 water, 6 water/minor island, 4 water/major islands, and 2 water/land regions. So more bad math ((x/20)*12), 12 sides means we get 5 water, 4 water/minor, 2 water/major, and 1 water/land regions. Adds up to 12 holy shit. Lets throw those on the map arbitrarily.

W being water with no appreciable islands, an ocean. W/Mi being minor islands, examples being the Central Pacific or Caribbean. W/Mj being major islands, like Indonesia. W/L being half and half land, like Europe and the Mediterranean.
