As someone with too many jobs. two small boys, and not enough sleep, I rarely get to just create maps or do analysis that is just for the fun of it. Thank goodness other people have plenty of time on their hands and creative minds that need stimulation. Cory of Cory's weblog has created a map showing the center of gravity for all Starbucks in Manhattan. For the uninitiated, the center of gravity, or center of minimum distance as it is know in some circles, is the location that is closest to a series of points or locations. This method is commonly used in geographic profiling of crime series as a proxy for a home base of an offender. While I am not sure too many people are going to run out and book a room at the exact center of gravity, it is a fun and interesting map that takes advantage of a good spatial analysis technique.
