Researchers at the MIT Senseable City Lab have developed a new way of measuring how “green” a city is using Google Street View. The project, called Treepedia, presents an index of cities by measuring their “Green Canopy,” the aboveground portion of trees and vegetation you can see as you walk around.
The maps reflect the data collected by the team and the city’s corresponding Green View Index (GVI), the measurement of the percentage of canopy coverage in a certain area according to human perception. By using Google Street View instead of satellite imagery, the team measured the cities through the eyes of the everyday pedestrian.
The MIT research team worked with the World Economic Forum and its Global Shapers Community initiative to put together Treepedia and they continue to collect information to add cities to their list of indexes available for comparison.
By providing quantifiable data about tree coverage, the Treepedia team hopes cities and their citizens will take the initiative to advocate for more trees in their communities. They also hope to add features to the site down the road that will help citizens tag trees in their area and alert their local authorities about areas in need of greater tree coverage.
Although the planting of trees may seem inconsequential in the grand scheme of urban development, Treepedia reiterates the benefits of tree-lined streets for city living. “As many cities experience warming temperatures, increased storm frequency, and continued air pollution, the well-being of our urban trees has never been more important,” said Carlo Ratti, director of the Senseable City Lab, in a press release. “We present here an index by which to compare cities against one another, encouraging local authorities and communities to take action to protect and promote the green canopy cover.”
