The other day, I was thinking about about the geographic orientation of Major League ballparks — my hometown Giants' park faces due east, but did they all face the same direction? I looked up a few, but then decided to put a quick page together that shows satellite images for each (using Closure and the Google Static Maps API) during commercials during the NLCS game 2. Source is here. North is up.
Turns out, they range from north-northeast, rotatating clockwise to south-southwest. Note that the Twins' Twins Stadium and the Rays' Tropicana field are omitted for lack of satellite imagery. This is from the 2010 season.
