There are a kajillion taxi rides happening in New York at any given moment. Thankfully, the NYC open data site shares the data for those rides, including pickup/drop-off locations, fare, tip, cash/credit, duration. I was interested in the terrain of generosity. Based on where you were picked up or dropped off, how likely were you … Continue reading Taxis | Tips | Cash | Rich | Poor
I realized last week that I never really shared out a map I made last year as for-giggles eye candy poster for an Oceans GIS Forum. Anyway, what better way to promote the adventure and mystery of the oceans then to piece together, plastic brick by plastic brick, a Science of Where Undersea Adventure bathymetry … Continue reading Lego Oceans

Many thanks to Dylan Moriarty who helped me navigate the tantalizing, but somewhat intimidating, world of OpenStreetMap extracts. And thanks to Ken Field and Wes Jones for their graphical advice. I am surprised at the remarkable variation in scale (Hong Kong??) … Continue reading Airdrome

The tornado season is like a wave that forms in the gulf, crashes over middle America, then rolls back to the sea. There are a million ways to show movement (here are some … Continue reading Animated Tornado Tree Rings

This map uses a variant, where instead of scaling the rings chronologically, like a tree, they are scaled by local aggregated tornado intensity, while the colors indicate … Continue reading Tree Ring Symbology
Here is a map of the seasonal migration that tornadoes take. Tornado migrations can be mapped like birds or wildebeests or commuters. Like just about everything else on this amazing planet of ours, they have a seasonal circuit and an ebb and flow. I live in Michigan, where I’m coming out of another winter.
