Thanks to funding by the Gaylord and Dorothy Donnlley Foundation, USC SCFloods, and other generous private and public donors, USC’s Government Information Department is able to make their historic aerial photography collection, spanning the 1930s to the 1980s, available online as georectified images. This site is user-friendly on laptops, tablets and phones. There is a transparency bar for viewing old and new images simultaneously . So far seventeen counties, including Charleston and Richland, have been added to the map. Start with the search icon, choose your county and then a year. We will be adding counties as they are finished.
