The use of aerial photographs and images from remote sensing to measure terrestrial features. See J. Photogrammetry & Remote Sensing. Photogrammetry employs high-speed imaging and the accurate methods of remote sensing in order to detect, measure, and record complex 2-D and 3-D motion fields; it is ‘the art, science, and technology of obtaining reliable information from noncontact imaging and other sensor systems about the Earth and its environment, and other physical objects and processes through recording, measuring, analyzing and representation’ (International Society for Photogrammetry and Remote Sensing).
