How to measure tree canopy coveragePARTNER FEATURE
The urban forest and tree canopy coverage is critical in mitigating the ongoing effects of climate change, providing thermal and shading benefits that increase safety and livability for residents. The urban environment is developing rapidly, replacing trees and green spaces with hard surfaces and creating urban heat islands.
Developing tree canopy policies supporting broader climate change mitigation strategies requires quality base data and ongoing measurement. Spatial tech company Aerometrex tested multiple methods for mass-measuring tree canopies and found how different solutions suit different objectives.
