Impervious Surface Growth in Cookeville and Algood (2008-2012)

Imperious surfaces (IS) are characterized as those which water cannot permeate. Pavements like roads, sidewalks, driveways, and parking lots are examples, as are rooftops, bricks, stone, and concrete. IS can be classified from aerial imagery and shown on a map revealing where urban areas have developed and are developing.
