Phys .org: Los Angeles and Google partner on ‘Tree Canopy’ project. “Los Angeles and Google have struck a partnership to track canopy density in the huge metropolis to determine which neighborhoods need more trees as a means of fighting extreme temperatures. Vegetation, notably tree canopy coverage, plays a key role in offering the kind of relief that Los Angeles needs: The city is the state’s biggest urban heat island thanks in no small part to thousands of miles of roads and parking spaces.”
