The revolution promised by digital photogrammetry is dependent on extensive, successful automation at many stages of the production process. The progress of automation is uneven. Digital cameras are not in widespread use. Scanners are available which include roll film transports and automated orientation, but set up for optimum tonal transfer remains interactive. Extensive automation of several operations on digital photogrammetric workstations, such as generation of digital terrain models, orthophotographs, mosaics and perspective scenes, contrasts with feature extraction, where robust products lag behind success in research. Progress towards practical automation to assist, but not replace, the human operator is significant, however, and examples are given from the Leica‐Helava systems.
