I apologize if this is something that
A) has been addressed elsewhere
B) is a guarded trade secret
or
C) creates a centipede's dilemma,
but I'm trying to get into programming and I'd love to know how exactly the randomly generated maps are built up.  I mean, I'm assuming it's a bit more complicated than Tile = random.choice([Land, Water].  I'm also assuming it's not in Python, but really, I'm only looking for broadstrokes advice.  Does the generator randomly choose a spot for the ocean and then have water tiles leading to it?  Or do the springs and streams come first?  How interconnected are all the elements?  Anyway, anything you care to share on the subject would be much appreciated.

If you want a response from Toady, your best bet is to ask here: http://www.bay12forums.com/smf/index.php?topic=159164.0

Put your question in lime green.
It probably takes into account the drainage, rainfall, and elevation maps (which you can see by exporting from legends mode.) These maps are generated via fractal terrain functions, which you can find tutorials for on the internet.

Oh! Okay, thanks.

There's a high-level overview of the world generator about halfway through this article:
