About this event
The Aerial History Project is an international effort to restore, digitize, stitch, and study a massive collection of aerial photography collected by the United Kingdom beginning in 1946 across 65 countries in the then British Empire. This mega-archive represents a unique source of high-resolution historical information in an otherwise data-scarce context. We develop novel systems of robot-assisted scanning and large-scale image-stitching used to recently complete a reconstruction of the African and Caribbean record, resulting in a historical digital resource of unprecedented scale. We apply machine learning to transform this image-based record into structured geographic information that we study to gain new insights into urbanization, economic development, and environmental change during the 20th century.
