LiDAR based urban tree inventory permits a better evaluation of tree services: an example from Montréal Canada
Current trees inventories are often based primarily on public trees while private trees are not captured. LiDAR technology permits a complete evaluation of all trees in a city; quickly quantifying tree position, tree height and crown volume and area. Our work showed that simple rules of thumb such as the number of private trees is equivalent to the number of public trees is not a valid generalization as the ratio varies greatly by neighborhood. We also showed a stronger relationship between noise levels in the city of Montreal and tree characteristics than with canopy cover or NDVi. LiDAR offers great potential for evaluating many tree related services in the urban forest.
