The 1949 Aerial Mosaic and Photographs in the Planning Atlanta collection consist of 124 individual aerial photographs of Atlanta and a unified mosaic composite of each aerial. Each aerial photograph and the mosaic composite can be viewed as overlays in both Google Maps and Google Earth and can also be downloaded as a GeoTiff image file. The mosaic overlay serves as a detailed record of Atlanta at its most densely populated point in time. It also provides a portrait of the city as a compact urban environment in which the central business district is the clear economic nucleus and where the urban fringes only hint toward the suburbanization that would later turn Atlanta’s urban form inside out.
The 1949 aerial photographs were originally digitized and made available online in 2001. With funding from the University Library Innovation Fund, this early digitization project was updated by georeferencing each photograph and then stitching all 124 photographs together into a single mosaic overlay. The overlays were created using ArcMap and MapTiler.
