Mapping the Treetops

Treepedia is a growing resource on city trees. The website maps tree information onto visuals from Google Maps. "Rating a huge number of street corners for the relative greenery of their appearance, Treepedia also allows browsers to click on a series of dots that reveal street view images of the location in question," writes Feargus O'Sullivan for CityLab.

While the site currently only maps around ten cities, it's a growing resource that could someday contain information about streets all over the world. The tool should allow residents to compare neighborhoods within their cities and cities to each other. Giving a visual, quantifiable testament to tree cover may make it easier to examine the issue in terms that are concrete and compelling.
