High resolution photographs taken from aircraft which are used to assess features in a study area, which are also used to produce topographic base maps of varying scales for alignment studies, engineering, and final design work.
The method of taking photographs from an aerial platform (aircraft). 1) Vertical photography, sometimes called orthophotography is used for photogrammetric mapping and requires a high degree of accuracy. 2) Oblique photography is used for general information, sometimes to verify certain attributes, but does not provide accurate measurements for photogrammetric mapping.
Aerial photography is any photography taken from the air. Typically, aerial photographs are taken with specialized, high-quality, large format cameras that point down vertically from the aircraft to the ground below. Orthophotography is derived from overlapping vertical aerial photography.
The process of taking photographs from a camera mounted in an airplane or balloon. The resulting photographs may be classified as vertical or oblique depending on the angle of the camera with respect to the Earth's surface at the time of exposure. Aerial photographs are used extensively in cartography to provide detailed geographical information in the production of base maps.
Photographs of a part of the earth's surface taken by a camera mounted in an aircraft for mapping purposes. This usually consists of a series of overlapping vertical photos taken in strips which can form the basis for mapping.
Aerial photography is the taking of photographs from the air with a camera mounted, or hand held, on an aircraft, helicopter, balloon, rocket, kite, skydiver or similar vehicle. It was first practiced by the French photographer and balloonist Nadar in 1858. The use of aerial photography for military purposes was expanded during World War I by aviators such as Fred Zinn.
