The Problem of Orientation in Photogrammetry from the Phototheodolite to Earth Resources Satellites
The term photogrammetry has been in use for about 100 years, its two constituents, “image” and “measurement”, representing the two essential components which characterize the discipline. Until recently these concepts were restricted to photographic images and to purely geometrical measurements. Photogrammetry is in principle an indirect measuring method as it refers to the image as a basic tool. The image is used in two ways: First, it is the source of information for the interpretation process, i.e. for recognition and identification of objects, and secondly is the basis for measuring and deriving geometrical properties of objects, including their horizontal and vertical positioning.
