Historical aerial photographs are very useful data to many researchers. Countries have used aerial photographs to capture geographical space since the late 1920s. They can provide an excellent visual picture of an area to understand the changing environment of a landscape. Aerial photographs are used by different government agencies, academic researchers, non-profit organizations, and commercial companies to create and update maps, and to study the environment, climate change, etc.
This talk covers a recent collaboration between the speaker, Wangyal Shawa, GIS librarian, with a history professor at Princeton University to process over 1,000 contact prints of historical aerial photographs of Northern Namibia taken in 1943 and the 1970s. The presentation includes a description of the workflow of scanning and creating an orthorectified mosaic image from historical aerial photographs and the type of tools we hope to develop to extract data from the aerial photographs. This program was held at Fine Visualization Lab in the Engineering Library.
