CITYgreen from American Forests is GIS software that is an extension to Esri ArcGIS. There are two versions of CITYgreen. One works with ArcView 3.x and the other with ArcGIS 8.x and higher; these are not interchangeable. The most recent version works with ArcGIS 9.2 and requires the Spatial Analyst extension from Esri.
CITYgreen analyzes the ecological and economic benefits of tree canopy and other green space. The analysis is based on a land-cover dataset provided by the user. The source of the land-cover dataset can be derived from a variety of sources such as aerial photography or satellite imagery. The imagery should be leaf-on, color, with a four-meter or better resolution so individual trees can be identified. The dataset must be classified into various land-cover features, such as tree canopy, open space, impervious surfaces, and water, before CITYgreen can analyze the data.
