O'Neil-Dunne of UVM demonstrates use of LiDAR in tree canopy assessment

Urban Tree Canopy - LiDAR News:
It may sound like an oxymoron, but it turns out that there is a growing (no pun intended – really) interest in accurately measuring urban tree canopy. A leader in the field, Jarlath O’Neill Dunn uses LiDAR and context-based analysis to develop dependable estimates. This article helps to demonstrates the importance of doing this right the first time.
During a visit to his Spatial Analysis Lab at the University of Vermont last week he gave my son and I some insight to the challenges of trying to automate the identification of trees in an urban setting, especially with leaf off LiDAR. Automating the process of detecting tree canopies is just not that easy.
