Treepedia by Carlo Ratti, Newsha Ghaeli, Wonyoung So, Xiaojiang Li, & Ian Seiferling

Treepedia measures the canopy cover in cities. Rather than count the individual number of trees, we’ve developed a scaleable and universally applicable method by analyzing the amount of green perceived while walking down the street. The visualization maps street-level perception only, so your favorite parks aren't included! Presented here is preliminary selection of global cities.
