Trees provide environmental, economic, and social advantages in urban areas. Knowing the extent and location of tree canopy in a municipality is an important step in quantifying these benefits. Spatial and temporal tree canopy analysis was performed for the city of Columbus, Georgia, by categorizing the National Agriculture Imagery Program (NAIP) aerial imagery for 2005, 2010 and 2015 into tree versus non-tree land cover type using unsupervised classification procedures. Air pollution removal rates from the i-Tree program were applied to this evaluation providing an estimate of the city’s tree air quality benefits. The city’s canopy overall has remained steady at …
