I do some storytelling. Sometimes with words, sometimes with maps :-).

Apparently the trick with channeling prolific worldbuilding into writing is to not try to use all you construct. While the length and definition of your world's distance measure may matter to a story, and can be part of many plot-necessary things, it doesn't have to be detailed to the reader. Too much of that, and the writing becomes encyclopadiac instead of tightly plotted. Nothing wrong with creating the encyclopedia yourself, so you know where your characters have to go to get across the countryside, how they dress for the occasion, and just what the spy from A noticed in the courtesan from B's demeanor that made him suspect she had been born in C and her loyalties really lay with D. Now, if you're clever, you could create that chain of logic backwards, from desired result back to plausible causes, with intriguing twists along the way. But you could also let it arise going forward, letting your plot twist according to the details of your constructed world. <shrug> ... whichever floats your boat.

For me, much of the story comes straight from the geography.
