1) Determine your terrain types
   e.g. desert, plains, beach, tundra, taiga, forest, boreal... etc.
2) make a 3x3 grid, and create a radial transition between each type
3) slice up the resulting image into tiles
4) create a map using large tiles, say 16x16, you might look at the diamond
square algorithm.  Limit your shades of grey to the number of different biomes

alternatively, you might use a 2d cellular automata: Split the tiles into
categories - center (can only border on it's own type), north edge (can only
connect to a south edge or a center of the border type...
