aerial and satellite photography
aerial and satellite photography technology and science of taking still or moving-picture photographs from a camera mounted on a balloon, airplane, satellite, rocket, or spacecraft. In the 19th cent., photographers such as Thaddeus Lowe and George R. Lawrence took impressive pictures with cameras suspended in hot-air balloons or hung from kites, demonstrating both the scenic and military value of aerial photography. With the development of aviation, photogrammetry (the science of making measurements and maps from photographs) became an important tool. During World War I and subsequent conflicts, aerial photographs provided vital intelligence. Military aerial photography has now advanced to the point that the rank of a foot soldier can be determined from photographs taken from high-flying planes and satellites. Because of its military importance, much of the most sophisticated surveillance technology remains classified.

aerial photography
aerial photography The taking of aerial photographs of rock exposures and of the ground surface for purposes of geologic interpretation. The photographs may be taken vertically, or at a high-oblique or low-oblique angle, and may be assembled like a mosaic to provide a picture of a large area. Stereoscopic cameras (two cameras within a single body) may be used to produce pairs of pictures that provide three-dimensional pictures when observed through a stereoscopic viewer. See PHOTOGEOLOGY.
