Cornell AAP’s Design Across Scales lab has developed a Tree Folio for New York City. Tree Folio is the development of a high fidelity understanding and modeling of each individual street tree in New York City. This includes the trees physical dimensions, species information, and its interactions with surrounding environments and infrastructures. Folio is comprised of a new database that draws from the NYC 2015 tree census survey and the 2017 NYC LIDAR survey. These datasets are combined and processed to produce a 3-D model that can be used to represent the highly localized impacts of street trees and develop strategies for more effective tree placement and maintenance.
