Definition

The numerous application areas for photogrammetry can be categorized into two major groups: topographic applications based on aerial and satellite imagery, and close-range applications.

Historical Background

Photogrammetry was invented between 1850 and 1860 independently by the French Laussedat and the German Meydenbauer. Aerial photogrammetry became a focus with the development of aircraft and fast film material. It was further developed by the coming of color film and, in the second half of the twentieth century, by satellite imaging systems. The photogrammetric industry developed analog optical and mechanical stereo plotting devices and image rectifiers to meet the practical demands. Since the 1960s, computer-based analytical processing methods have been used intensively. Consequently, digital photogrammetry became state of the art in the 1990s, when digital imagery and digital...
