Sprawling of Atlanta Visualizing Metropolitan Area Change, 1940s to PresentThe Sprawling of Atlanta digital project invites the public to visualize the extensive built environment and demographic changes that have occurred throughout the metropolitan region from 1940 to the present. The project offers georeferenced and stitched together aerial imagery overlays of the five core metropolitan counties (Fulton, DeKalb, Cobb, Gwinnett, and Clayton) with one aerial mosaic layer for each decade beginning with 1940. Additionally, our project incorporates census tract-level data from Atlanta Regional Commission’s annual Population and Housing estimates and from the Census Bureau’s Decennial Census and American Community Survey.
