Aerial photography is the method of taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken by a photographer, triggered remotely or triggered automatically. Platforms for aerial photography include fixed-wing aircraft, helicopters, balloons, blimps, kites and other airborne systems. Tradionaly they are produced in photogrammetric surveys, which are often the basis for topographic maps, land-use planning, archaeology, environmental studies, surveillance, commercial advertising, and other such projects.
