Walking with green scenery: Exploring street-level greenery in terms of visual perception

A potential application of LiDAR data in street-level greenery assessment has been explored in this study. Taking full advantage of the fine-scale tree structure modeling of LiDAR data, we propose a new green view index calculation method to assess street greenery visualization. Results indicate that LiDAR data is capable of differentiating the amount of greenness being perceived from different sites and the calculation method gives an objective measure of street-level greenery.
