On December 6, 1906, aerial photographs of Stonehenge were shown at the Society of Antiquaries of London, England. A member of the Royal Engineers took the photographs from a hydrogen balloon a few months earlier. These aerial photographs were among of the first to be used in studying archaeological sites.
The technology used in aerial photography, already 50 years old, was slowly improving. Balloons with hot air or other gases, kites, rockets, and even pigeons were used to carry cameras.
Once airplanes were widely available, though, aerial photography took off! Aerial photographs are often used in weather forecasting, where meteorologists examine cloud formations to predict temperature or precipitation patterns., Aerial photographs are also used for measuring glaciers’ winter growth and summer melt, identifying spots where forest trees are missing, and planning a city’s growth.
