As policymakers aim to plant more trees to increase shade on warming city streets globally, Google has launched Tree Canopy Lab that combines Artificial Intelligence (AI) and aerial imagery. The platform will help cities see their current tree canopy coverage and plan future tree planting projects, starting with Los Angeles.
"Trees are increasingly seen as a solution to both lowering street-level temperatures while improving quality of life. Yet many cities may not have the budget or resources to locate where every tree in town is, or where new tree-planting efforts are most needed," Google said in a statement.
Tree Canopy lab is part of the Environmental Insights Explorer platform, a tool that makes it easier for cities to measure, plan, and reduce carbon emissions and pollution.
"With aerial imagery collected from planes during the spring, summer, and fall seasons, as well as Google AI and Google Earth Engine's data analysis capabilities, we can now pinpoint all the trees in a city and measure their density," Google said.

Google uses a specialized tree-detection AI that automatically scans the images, detects the presence of trees, and then produces a map that shows the density of tree cover, also known as "tree canopy."
The lab can help anyone identify residential blocks with high tree planting potential and locate sidewalks that are vulnerable to higher temperatures due to low canopy coverage.
"With Tree Canopy Lab we've found that more than 50 percent of Angelenos live in areas with less than 10 percent tree canopy coverage and 44 percent of Angelenos live in areas with extreme heat risk," Google said. The Tree Canopy Lab will be available to hundreds of more cities in the year to come, the company said. (IANS)
