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 imaging devices came into use. In close-range photogrammetry, the main fields of application were addressing architecture and cultural heritage, accompanied by a variety of very specialist applications and solutions. With the development of self-calibrating bundle adjustment programs around 1980, industrial photogrammetry was strongly used mainly for large scale metrology, e. g., for antennae or in the aerospace industry. Again, the development of high-resolution digital cameras pushed the technique further ahead. Nowadays, photogrammetry is an accepted and widely used tool in many industrial, medical, and engineering tasks.

Aerial Applications Applications in aerial photogrammetry can be characterized by often similar imaging configurations, i. e., equal or similar cameras, nadir imagery, large imaging distances (flying height) and image scales usually between 1:2,000 and 1:30,000. The most important products of aerial photogrammetry are orthophotos, 3-D terrain and city models, and vector data usually used as input for geographic information systems (GIS). The following examples show a small spectrum of the applications in aerial photogrammetry.

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

GIS Data Acquisition Photogrammetric data generation for GIS purposes is the most important application of aerial photogrammetry. An example of photogrammetr
