"The term aerial archaeology is used to describe the various processes relating to the discovery and recording of archaeological sites from the air. These activities include both the actual taking of photographs and the mapping and interpretation of archaeological sites visible on aerial photos. Aerial survey is one of the most important tools for the discovery of archaeological sites in this country [UK]. Each year hundreds of previously unknown sites are discovered and photographed through aerial reconnaissance." Source: Historic Cornwall (PDF).
