Remote sensing deals with the art and science of observing and measuring items on the Earth's surface from a distance. By this definition remote sensing encompasses the field of aerial photography. The term, "remote sensing," was first introduced in 1960 by Evelyn L. Pruitt of the U.S. Office of Naval Research. However, the first aerial photograph was taken in 1858, 102 years before the term "remote sensing" came into existence. Long before satellites and microcomputers started dominating the field of remote sensing, people were taking pictures of the Earth's surface from afar. Taking these pictures was not an easy task and people risked their lives to bring about the development of the field.
In 1903, Julius Neubranner, photography enthusiast, designed and patented a breast-mounted aerial camera for carrier pigeons (Figure 10). Weighing only 70 grams the camera took automatic exposures at 30-second intervals along the flight line flown by a pigeon. Although faster than balloons they were not always reliable in following their flight paths. The birds were introduced at the 1909 Dresden International Photographic Exhibition. Picture postcards of aerial photographs taken over the exhibition were very popular. They were used at other fairs and for military surveillance. Two sample pictures are provided below. One can see in the one picture the tips of the bird's wings as it flew across a palace.
