i-Tree

There are seven different i-Tree applications which can enhance an individual's or organization's understanding of the benefits which trees provide in modern society. Over the course of many years the U.S. Forest Service has developed and refined these different applications: i-Tree Eco, i-Tree Landscape, i-Tree Hydro, i-Tree Design, i-Tree Canopy, i-Tree Species, i-Tree MyTree, i-Tree Streets, and i-Tree Vue. i-Tree began in 2002 as survey of a sample of urban forest to simulate taking a tree inventory of an entire urban forest. It then added hand held devices for efficient inventory of street trees. The current version of i-Tree includes different tools which allow for several sources of data to be used, such as National Land Cover Data, Google Maps, and tree inventories. Some tools use continuous data on air pollution and meteorology for more accurate results.
