Trees, cabs and crime in San Francisco
(Check out the big version!)
I've had this idea to use subtractive blending so that you can see where these three data sets overlap for a while, and decided to scratch the itch this weekend. I'm still not sure if it's significant or even interesting, but here it is. This is a slightly improved version of
the original with a more useful (and attractive!) legend and no base map. The colors have also changed: Trees are cyan and crimes magenta because I felt that the latter should stand out more. And yellow combines with magenta to produce red, which seems to me a more crime-y color.
Urban tree locations come courtesy of Friends of the Urban Forest, one day's worth of taxi cab locations from Yellow Cab (via Cabspotting), and a week's worth of reported crime incidents from Crime Reports.
Best, obviously, viewed at original size.
